Cutting Metal is Easy With a Hacksaw and the Right Blade
Metal isn’t hard to cut, and a hacksaw isn’t difficult to use. That’s not our opinion, that’s a fact. But with all the power tool options available today that cut metal, such as jig saws, reciprocating saws, circular saws, and abrasive wheel chop saws, you might ask whether you should bother with this old-school metalworking tool. There are several good reasons to learn how to use one: Hacksaws are simple devices that cut metal quickly, accurately, and quietly. They don’t have batteries that need to be charged. A small selection of blades will take you through an incredible range of work. Furthermore, hacksaws also cut ceramic tile and plastics.
Below we show a few great hacksaws and blades, and explain the fundamentals of using this great tool.
Hacksaw Basics
The immutable law of hacksaw knowledge boils down to this: Thick materials require a blade with fewer teeth per inch, while thin materials require a blade with more teeth per inch. Simple, right?
The goal is two have a minimum of two hacksaw teeth in contact with the material, while not increasing the tooth contact to the point where the blade clogs with the waste particles that it is producing. That is, if you cut thick material (say a half inch thick) with a blade that has a large number of teeth per inch (say 24 or 32 teeth), you’ll find it tough going. The fine teeth become clogged with metal particles. It’s much easier to cut such a thick piece of metal using a blade with 14 or 18 teeth per inch. Teeth per inch is abbreviated as TPI.
The same holds true for cutting something thin, like sheet metal. If you try cutting that with a 14-tpi blade, you’ll find that the teeth will snag on it. The cut goes much more easily when you switch to a 32-tpi blade.
Common hacksaw blades are available with 14, 18, 24, and 32 teeth per inch. For metal that is in the vicinity of 1/16-inch thick and thicker, use a blade with 14 to 18 teeth per inch. For metal that is thinner, use a blade with 24 or 32 teeth per inch.
Hacksaw Hacks
Every hacksaw owner should take these hacks to heart. They’re few in number, but they’re important and will help you master the art and craft of cutting metal by hand.
Three typical bi-metal blades will see you through virtually every cut you will need to make. If you intend to cut ceramic tile, buy a hacksaw blade with a tungsten-carbide grit cutting edge.
Three typical bi-metal hacksaw blades (top) and a carbide grit blade (bottom). The top three blades can be used in either a standard-tension hacksaw or in a high-tension hacksaw. So long as you don’t overtighten the carbide grit blade in a high-tension frame, it will work in a high-tension saw frame without snapping. The tooth counts on the three top blades are the three common types that you should own: 18, 24 and 32 tpi (teeth per inch). If you expect to saw very thick sections of metal or thick sections of soft materials (brass, copper, plastic) then add a 14-tpi blade.
Use Oil
Metal workers argue about this incessantly, with people forming two camps—“oil” and “don’t oil.” I’m an oiler. People say that oil causes metal particles to stick to the blade. My response is that the metal particles will stick to the blade whether you oil or not. The issue is whether the particles will slide around more freely and whether the teeth themselves can slide more freely over the metal.
Apply a little oil to the hacksaw blade before beginning, and reapply as needed for thick cuts. Hold the oil over the blade and apply a few drops. Use a shop cloth below the blade to catch what drips off.
People worry about what oil they should use to lubricate their metal cutting. My response, as an oiler, is that almost any oil is better than no oil. The same motor oil that you use in your lawn mower (10W-30) will work. So will the bar and chain oil that you use in your chainsaw. If you use a thinner oil, such as spraying the cut with WD-40, you’ll find it will work, but it will be messy and you’ll need a lot of it.
If you’re cutting thick material, pause occasionally and add more oil to the cut surface and the blade. Use a disposable piece of shop towel to catch the runoff.
And if you really want to lubricate the cut properly, use a dedicated metal-cutting lubricant like Tap Magic.
Just remember to use a part cleaner or solvent to remove any trace of oil if you want to weld or paint the metal after cutting. Lubricant residue will prevent paint and weld metal from sticking, so scrupulously clean the cut metal with solvent such as a spray-on parts cleaner or degreaser.
Clean the Blade
Whether you lubricate the cut or not, metal particles stick to the blade, as does paint from the cut part, rust, accumulated carbon, and good old-fashioned dirt that somehow found its way onto the surface. Don’t put the hacksaw away until you flush the blade clean with spray lubricant.
Use a spray lubricant or spray parts cleaner to clean the blade after you’re done. Hold a piece of paper towel or a shop rag under the blade to catch the materials that drip off of it. Wipe the blade clean and then store the hacksaw.
Begin With an Angle, Finish Horizontally
When cutting square and rectangular bar stock (or square tubing) start with the saw held at an angle.
Use an awl or a carbide-tip scribe to score a cut line across the stock. Tip the hacksaw at an angle. With light pressure and short strokes establish the cut.
Once the angled starting cut is well established, move to a horizontal cut. If you start the cut by sawing horizontally, the saw will slide off the cut line.
Once the cut is 1/16 inch deep or deeper, begin sloping the saw back until the cut line is horizontal to the top surface. Use medium pressure and take full strokes, using the entire length of the blade. Pause occasionally to relubricate the saw and the material you’re cutting.
Standard Versus High-tension Saws
A standard hacksaw holds the blade with relatively low tension. The blade is placed in the frame and tightened by turning a small wingnut at the rear of the frame.
The standard hacksaw is a low-tension cutting tool. You place the saw in the frame and tighten its wing nut. With these saws, you can use either a carbon steel blade (shown) or a bi-metal blade (shown everywhere else in this article. These inexpensive saws are perfectly fine for cutting small pieces of mild steel (such as small-diameter rod, up to 3/8 inch) and small pieces of tubing (up to 3/4 inch). However, because their blades are not held under much tension, they don’t work particularly well in cutting thick or large pieces of metal.
Many hacksaws today are high-tension types. These saws are equipped with a blade-tensioning mechanism that exerts thousands of pounds of tensile force on the blade to hold it tightly in position. This enables the blade to last longer and make a straighter cut, particularly in tough or thick materials.
A high-tension hacksaw has a blade tighening mechanism that applies thousands of pounds of tensile force to tighten the blade, holding it rigidly in place. These saws require a bi-metal blade which has high-speed-steel teeth electron beam welded to a back strip of flexible steel. These blades can withstand the high tensile force that the frame applies to the blade. Installing an ordinary high carbon steel blade in these saws is to risk snapping the blade and sending a piece of steel flying through the air.
Installing a hacksaw blade is simple. Standard hacksaws use a simple mechanism (fit the blade in place and tighten the wingnut). High-tension hacksaws differ as to the tightening mechanism they use.
What Is a Hacksaw? | Parts of Power Hacksaw | Driving Mechanism of Power Hacksaw | Working of Power Hacksaw
Hacksaw is hand-operated, used for cutting small toothed metal pipes, rods, brackets, etc. Huxos can also cut through the plastic. The hacksaw has a U-shaped frame a handle at one end. Hacksaws have smalls pins at each end of the frame that receives a blade.
A tensioner nut or knobs is then used to extend the length of the frame, which puts tension on the blade locks it in place. The blade can be installed for cutting on push or pull strokes; Cutting is more common on push strokes.
When a hacksaw is operated using machines, it is known as a power hacksaw. It is a type of rotating saw machine. Power hacksaw is used when materials cannot be cut to hack by hand.
When the cutting diameters of the material to be cut are large, it is very difficult to cut with a hand-cut hacksaw, in which case power hacksaws are used. Power hacks can cut large diameter or workpiece workpieces that require a large amount of time hard work to cut.
This machine can be used to cut any type of material in workshops as the hacksaw blade used is made of HSS (high-speed). Some cutting fluids are provided in this machine to cut hard materials.
Parts of Power Hacksaw:
#1. Base
The base of the power hacksaws is made using cast products. All the other parts of the power hacksaws are carried by this base.
#2. Column
The first part of the powers hacksaw is the columns. This column is a housing for the drivings mechanism of the power hacksaws, the electrical cables are also present inside this column.
#3. ON/OFF Switch
These switches are used on and off. These devices are connected to an electrical connection can be switched on and off using these switches.
#4. Support
In front of the column, there is two support, one is horizontals support, and another one is verticals support. The vertical supports the horizontals frame or support.
#5. Machine Vice
Machine Vice is present above the horizontals support. This machine’s vice is used to clamp the workpiece, i.e., hold the workpieces tightly. These vices are adjustable so that various sizes shapes of metals can be held.
This machine’s vice has been handled. The vices can be tightened or loosened by turnings the handles. This vice locks the workpiece does not allow it to move during the cutting operation. The size of the power hacksaws is determined by the largest workpiece that can be held in the vice.
#6. Cooling Pipe
Cooling pipe is used to provides coolant while cutting so that too much heat is not produced during cutting the hacksaw blade does not get blunt. These cooling pipes provide a coolant between the hacksaw the workpiece. These cooling pipes provide the coolant by the application of a pump.
#7. Power Hacksaw Frame
The power hacksaw frames are used to support carry the hacksaw blade. The power hacksaw frames are connected to the driving mechanism present inside the columns. These frames are also known as an arm. The hacksaw blade is fixed in this armor frame.
#8. Handwheel
The handwheels are present on the top of the handle are rotated to move the hacksaw frame up and down.
#9. Emergency Foot Switch
Almost every power hacksaw has an emergency footswitch to turn the power hacksaw on and off. This is added mainly to turn off the machine in emergency conditions. This footswitch is located on the front side of the machine.
#10. Hacksaw Blade (Cutting Blade)
The hacksaw blade performs the cuttings operation on the workpiece. The blade does cuttings in the forward stroke removes chip produced while cutting in the backward strokes. The blade of this hacksaws blade is made up of high-speed steel. Blades of power hacksaws are categorized based on the materials from which they are made and the number of teeth in the blades per inch.
The top category blade is made from High-Speed Steel (HH.S.S. But HH.S.S.blades are very expensive, so there are cheaper alternatives like carbon steels blade.
Generally, the number of teeth per inch varied from 14 to 24; as the number of teeth increases, the smoothness of cuttings also increases. The correct blade for a particulars workpiece is determined based on the material to be cut.
#11. Handle
A handle is attached to the column. These handles are used to move the hacksaw frame hence the hacksaw blade up and downs. Hacksaw blades are moved near the workpiece to performs the cutting operations.
Driving Mechanism of Power Hacksaw:
Two pulleys are placed on fronts of each other. One winch is on top of another. These two pulleys are connected by a belt. A link is attached to the pulley at the top. The link is connected to a pulley on one side and an electric hacksaw frame on the other side.
When the power hacksaws are switched on, the bottom pulley starts rotating, and since this lower pulley is connected to the top pulleys by a belt, the top pulley also starts rotating.
When the top pulley rotates, the link connected to the top pulley will also rotate. Since this link is connected to the power hacksaw frame, when the link moves back and forth due to the pulley rotating, the power hacksaw frame will also move forward and backwards. The rotational speed of the pulley will be converted into reciprocating motion in the power hacksaw frame.
So in this way, the driving mechanism of an electric hacksaw works. We can increase or decrease the speed of the pulley, and the feed of the forward and backward strokes can be adjusted into a power hacksaw.
The speed of the pulleys can be changed by changing the belt from one size pulley to another shaped pulley. If the belt is placed on a small pulley, the speed increases, and if the belt is placed on a larger pulley, the cutting speed decreases. Different types of metals can be observed at the proper speed by the change of speed.
Working of Power Hacksaw:
The vice of the machine has two jaws. One jaw is stable, and the other is flammable. There is a threaded row that is attached to the movable jaw on one side and a handle on the other side. When we rotate this handle, the movable jaws of the machine vice move forward and backwards on this threaded rod of the machine vice.
We can easily attach any workpiece in the vice of this machine to use movable. The cooling pipe then supplies the coolant during the cutting process between the hacksaw and the workpiece.
This coolant extends tool life, helps remove chips and removes heat generated during cutting, and keeps equipment and workpiece cool. This coolant acts as a lubricant to smooth the cutting process.
The hacksaw moves along the blade frame using the driving mechanism of the power hacksaw present inside the front and rear columns.
When the hacksaw blade is brought near the workpiece, and the switch is switched on. The driving mechanism begins, and the cutting process or the process of removing material from the workpiece.
A forward stroke of a power hacksaw is a cutting stroke that consists of a material removal process, and a backward stroke is a passive stroke. Cutting only during the forward stroke avoids unnecessary wear on the saw blade.

A backward stroke is used to extract chips from the workpiece produced during the forward stroke.
Frequently Asked Questions (FAQ)
Power Hacksaws
Power hacksaws are often used to cut large pipes, steel, cast iron and other hard materials. The straight blade is attached to the tool and moves back and forth across the workpiece to make the cut. Power hacksaws have a slower speed and longer stroke length than reciprocating saws, which slows the cutting speed but leaves a finer edge.
Hacksaw Parts
Following are the main two parts of a hacksaw:
What Is a Hacksaw?
A hacksaw is a handheld, small-toothed saw used to cut metal pipes, rods, brackets, etc. Hacksaws can also cut through the plastic. The hacksaw has a U-shaped frame and a handle at one end. There are small pins on each end of the hacksaw’s frame that receive a blade.
Small Hack Saw
Small Hacksaws easily fit in your toolbox or in limited spaces and are great for making fast cuts in small pieces of metal, wood and plastic – such as a metal rod, a block of wood or PVC tubing.
Electric Hack Saw
Power hacksaws offer a range of options for portable cutting of pipe, structural steel, tanks and other materials. The rechargeable electric saw is light and portable, long battery life, and will not damage the bark. This is a professional electric hacksaw tool. Electric hacksaw adopts high-quality tungsten steel material, durable and wear-resistant.

Hacksawing is a great way to cut a wide variety of materials.
Step 1:
Measure and mark the material to be cut.
Step 2:
Choose the right blade for the material you are going to cut. Typically, blades for harder materials such as metal will have smaller teeth than blades for softer materials such as wood and PVC
.It is often possible to cut softer materials with a metal blade, but difficult to cut metal with a wood blade.
Hacksaw blades only cut in one direction. The blade in the image only cuts when moving from right to left. Don’t try to cut in both directions by really bearing down on the blade; you can damage your blade that way.
Step 3:
Step up the material to be cut. If you don’t have a vise, clamp the material to the edge of a table.
Step 4:
Put on your safety glasses.
Cut the material with even strokes and slight pressure against the material (use a reasonable amount of pressure along the direction of the cut).
Step 5:
Smooth any sharp edges or square the ends of the workpiece by sanding, deburring, or other processes.
Step 6:
Vacuum or sweep up any chips and put away all tools.

Just so you know, your vice has a pipe holder built in. Pivot the arm 360 🙂 Of course you already know this, but I like to pretend to be observant.
Erm. Doesn’t pivoting 360 degrees bring you back to where you started? 180 degrees perhaps? ;]
You’re right! I was being lazy, and wasn’t worried about scratching up the PVC.
As a machinist, I was taught that the proper way to select a saw blade, whether it be hacksaw or whatever, is that a minimum of 3 teeth should be engaged into the workpeice when cutting. Thin materials need a finer toothed blade than a thick workpeice. If you are sawing something extremely thin, like a piece of tin, angle the blade to the workpeice so that at least 3 teeth are in contact with the workpeice and the results will be smoother and straighter. As you pointed out, there should be no downward pressure on the back stroke of the blade.
I just mentioned on my new instructable the importance of a good blades and Hacksaw, Life is better with a good constant tension style as described in my new post:
And A photo of my hacksaw and choice of blades.
Hacksaw Blade tool tips #shorts
And old salt once told me if you don’t like a hacksaw, its either lousy or do not know how to use it.
the instructor omitted to warn first time users of a hacksaw that the saw will suddenly go through the material on the final cut and most first time users will cut them selves on the projecting sharp edge. So be warned.
But is basic to know how to use tools this is a good one, more people should teach us how to improve techniques in how we must use tools and safety tips thanks
Always hold clamp work as close to the cut as possible to avoid vibration. remember that screeching noise is wasted energy. stand to the side of the saw, using a stance like the classic Weaver shooting position, hold the saw with BOTH hands one at the front for control and let the saw do the work. there is no replacment for good quality bimetalic blades for general work i use 24t.p.i.
Thank you for posting this valuable information. I’ve seen hacksaws used, but it is good to have an actual set of instructions with all the safety info.
“Instructables is a venue for showing what you make and how others can make it.” What next, a demo on how to open a door or maby how to use a fork. Haz
There’s people that don’t know basics as this one, but really want to start working on projects, so they have to learn these things.
