Bosch Cordless Grinder Review

When it comes to cordless grinders, a consumer has plenty of options to pick from. All most every major and no name power tool manufacturers have a grinder in their lineup. Like anything else in this world, we have brands we love and brands we want to avoid. For me, I have two major brands that I stick to when it comes to grinders, Metabo and Bosch. I have owned both of them over the years and they are the two that always seem to stand up to the abuse. So with that said, let’s jump into the Bosch Cordless Grinder review, model GWS18V-45CN and see if this grinder holds true.

Bosch Cordless Grinder Review Overview

Over the past couple of years, cordless grinders have made huge leaps forward. A couple of years back, a grinder would stall out very easily when a user put any pressure on the tool. With today’s grinders, they are much beefier and can perform a ton more work without cutting down or shutting off.

While you still have to be careful with your grinder purchases, the bigger brands have a better assortment of grinders that can be used in any application a corded grinder can be used.

Bosch Cordless Grinder Review Features

Bosch designed the grinder around a brushless motor. The GWS18V-45CN is a 4-1/2″ grinder which is one of the most common size grinders on the market.

Some of the most important features are features you can’t see such as protection for the user. The grinder has KickBack Control to reduce the hazard if the grinder binds. There is also drop control which shuts off the grinder if you drop it on the floor. The grinder also features restart protection and soft starts.

Here is what’s cool about this grinder. This grinder is designed with the use of the new Bosch Core battery. If you aren’t familiar with the Bosch Core battery, I would suggest checking out our article on the Bosch core. The new battery isn’t a gimmick, this a true breakthrough for the power tool world and the cordless power tool market. If you use the Core Battery, you will get a 110% increase in run time for the battery

The back of the handle has a nice design and is slim, which give this a good feel and makes it more ergonomic for longer periods of use.

The rubber overmold has some texture so even with gloves or dirt on the handle, you shouldn’t have a problem with control or the tool slipping.

The Bosch grinder uses a slide switch instead of a paddle switch. The slide switch can be pushed forward to turn the grinder on. If you want to lock the grinder on, you have to slide forward and then push down. The design still allows the user to quickly turn off the grinder and makes it easy.

The head of the grinder is much smaller than I would expect for a grinder of this size and power. This makes it great for tighter spots.

You can also see the arbor lock located on top of the tool. The arbor lock is easy to access and isn’t too awkward when changing accessories on the grinder.

bosch, grinder

The side handle is fairly comfortable and can be used on either the left or right side. I do like how Bosch designed this will a slight angle for the side handle. Some companies have decided to go with a straight 90-degree side handle, but this feels much more comfortable.

Taking off or adjusting the angle of the guard is easy and doesn’t require a tool. Just push a button and you can spin the guard to the correct location.

As you know when you grinding or cutting, you create small metal particles. Bosch has a screen to protect the air intake for the motor. These can be removed for easy cleaning. I am glad to see the screens included as it helps protect the tool for a longer life.

One cool feature of this grinder is the ability to use it for Bluetooth. Bosch sells a kit (GCY30-4) which is a Bluetooth tool module. We will cover this in the future but for now, you can read more about it on the Bosch Website. If you use this add-on with the Bosch Toolbox app, you will get more control over the grinder.

Bosch Cordless Grinder Review Performance

This grinder is specifically designed to get the most from the Bosch Core Batteries. So since we were testing the batteries, e used this grinder for a wide variety of applications. We tried to get it to bog down and for one thing, this doesn’t bog down like a lot of other grinders we have tested. When we were grinding, you could extremely hard and still not get the tool to cut out. So that’s a huge plus.

We cut through some rebar, metal pipe, and metal stakes. Again, the tool performed as advertised. As is quicker than other grinders we tested, no not necessarily. But the more we used the tool, the more we could see that the runtime has increased. We didn’t test it against other grinders for runtime as that is something we will do in the future.

Bosch Cordless Grinder Review Value

The Grinder will run about 179 as a bare tool on Amazon. If you want the grinder with the Core Batteries, you will have to open up your book a little wider and fork out 250. Now if your grinder is one of your main tools, then it’s worth it.

You can get some grinders for less, but when you couple this grinder with the Bosch battery, you do get a tool that tackles more jobs than a majority of other tools on the market.

Bosch Cordless Grinder Review Final Thoughts

Overall this is a great grinder. While I wish there were fewer vibrations, I love the fact that it doesn’t bog down like other grinders we have tested. Couple this grinder with the Bosch Core battery and you will see improvements in runtime over other 18V grinders on the market.

Over the years, Bosch has made some of my favorite grinders. They are tough and built to last. The addition of the GWS18V-45CN is another well-built tool that has a Brushless motor and the option for Bluetooth.

Bosch X-Lock Angle Grinder Mount GWX18V-50PC GWX18V-50PCN Honest Review

In this article we will be reviewing the completely new X-Lock angle grinder mount and also the new Bosch GWX18V-50PC GWX18V-50PCN 18V Brushless angle grinder featuring the new X-Lock mount. As a full disclosure, Bosch was kind enough to send me a product sample of the Bosch GWX18V-50PC angle grinder with new X-Lock Mount and several X-Lock mount wheels at no cost to me and as always I will provide my honest unbiased feedback. I am not paid or swayed in any way to give a positive review.

Why X-Lock?

  • X-LOCK wheel change – features snap-on mounting and grinder lever wheel release for change-out that’s up to five times faster
  • Tool-free disc swap – the wheel mounts properly without the need for a spanner wrench or flange nuts for no losable parts

So what makes the X-Lock mount so great? If you look at other types of tools like reciprocating saws, jigsaws and even oscillating multitools, in their beginnings their blade interface started off requiring tools to install. Then eventually they offered a way to replace blades without the need of tools. We call this progress and moving forward to simplify something that has to be done often. Going back to the angle grinder mount we have today, changing wheels still requires the use of a tool, namely a spanner wrench to install and a remove by tightening and untightening a locknut to replace wheels. You also need to press a locking button on top of the angle grinder to lock the wheel as it’s being replaced. The X-Lock mount does away with all of this and doesn’t require a spanner wrench for a completely tool-less wheel change but they also simplify the entire process. You also don’t need to tighten a locknut, you don’t have to press the lock button atop the grinder, actually you don’t have to tighten anything at all. They oversimplified the entire wheel changing process to the point that all you have to do to install a new wheel is to snap it into place, literally. And to remove the wheel, you pull on the lever on top of the grinder head and the wheel pops off. It doesn’t get any easier than this folks.

Bosch actually created the X-Lock mount and what’s interesting is that the design they used is very similar to the Starlock mount found on oscillating multitools, which was also co-developed by Bosch along with Fein. In it’s simplest form, the X-Lock mount is the same as the Starlock mount in the way that both have “teeth” in the center of the mount that are closed when no accessory has been mounted and these teeth open up and grip the accessory opening to lock into place. Both mounts also offer a lever to remove the installed accessory. The main difference is the opening of the mount as X-Lock and Starlock mounts have different shapes.

Those that swap angle grinder wheels often are the ones that will benefit the most from the new mount as wheel changes are as easy as snap on and snap off. I’ve even heard of users using two separate grinders on a project simply so they wouldn’t have to swap out wheels and with the X-Lock mount you wouldn’t need to as wheel changes are so darn fast and easy – unless you fancy using two grinders on a project.

I know there are some or many out there that don’t need to use a spanner wrench to remove grinder wheels and they might think the new X-Lock mount is pointless or has little benefit since many can swap out grinder wheels without the use of any tools. That’s because they either have tool-less locknut’s like Milwaukee’s Fixtec Locknut for example which doesn’t require a spanner wrench to remove wheels. Then there are those that change wheels simply by holding onto the wheel and tightening and untightening by hand. Many people do this and it’s an easy tool-free way of removing wheels so for people like this the new X-Lock mount might seem pointless. However even with this hand tightening method, it still takes some time and effort to swap wheels which the X-Lock mount minimizes with it’s snap on and snap off efficiency. Then we have to remember there are a couple of downsides of hand tightening such as you can’t fully tighten a wheel by hand as it will eventually keep turning until you use a spanner wrench to fully tighten – something you don’t have to worry about on the X-Lock as the X-Lock mount doesn’t require tightening. The other issue of hand tightening is actually a safety hazard, for example let’s say you’re installing a cut off wheel and some of these wheels are almost paper thin, when they are being manually hand tightened, there’s not much to hold onto and it’s so easy to bend these as you turn them and bending them runs the risk of fracturing them. A fractured wheel is a huge safety hazard as it can break when in use and fly off and shards can fly anywhere including your face or body and cause serious harm. You don’t run that risk with the X-Lock mount because wheels are inserted and locked into place rather than tightened. Another safety benefit of the X-Lock mount is that you don’t need remove wheels by hand. For example, while regular grinding and cut off wheels cool off quickly after use and can be handled with bare hands and not get burned, a diamond wheel for cutting masonry (tile, stone, etc) can remain hot and burn your hand if you are removing them without a glove. Because the X-Lock mount ejects wheels, you won’t have to worry about handling hot wheels.

So not only is the X-Lock mount faster, easier and tool-less compared to the traditional angle grinder mount, it also offers always fully tight wheel connections and no safety risks of fracturing paper thin cut off wheels as compared to manual hand tightening and also handling hot wheels such as diamond wheels since they are eject with an X-Lock mount grinder.

Another benefit of the X-Lock system is that X-Lock wheels are backwards compatible with regular angle grinders. This means that even if you don’t have an X-Lock grinder right now, you can go out and purchase X-Lock mount wheels and use them on your current grinder(s). This way you can build up your X-Lock collection so you’ll be ready for when you do buy a new grinder with the X-Lock mount.

bosch, grinder

X-Lock Perfect?

So is the new X-Lock mount perfect? Like most things, it is not perfect. While the X-Lock wheels are backwards compatible, the X-Lock mount itself is not backwards compatible meaning your regular angle grinder wheels won’t work. That’s because of the special shape of the X-Lock mount is larger than the opening of regular grinder wheel arbor holes. This means you will have to buy a new set of X-Lock wheels to replace each wheel you have over to the new mount which means more money to start.

I also noticed that the special mount shape for the X-Lock is one sided, meaning that only one side of each wheel will fit. Most wheels have the label side facing up which makes finding the correct side to install on very easy however some wheels have the label side facing down which can confuse you into figuring out which side to install on.

X-Lock Availability

At the time of writing in the USA there are only 5 X-Lock angle grinders you can purchase and all are from Bosch. They offer one cordless 18V and 4 corded models ranging from 99 all the way to 199. Currently, Bosch is the only brand in the USA that offers X-Lock grinders, however Makita also offers an X-Lock mount angle grinder but it’s not available here in the states at the time of writing.

As far as X-Lock wheels and accessories are concerned, Bosch offers a huge assortment of X-Lock wheels and the good news is that they are priced about the same as non-X-Lock grinder wheels so you won’t have to spend more to get X-Lock. Diablo also offers X-Lock wheels although not a wide variety like that of Bosch and also Makita makes X-Lock mount wheels as well with what seems like a wide assortment, however Makita’s X-Lock wheels aren’t sold in the USA at the time of writing. At the time of writing, unfortunately you can’t walk into a brick and mortar store to purchase anything X-Lock related, either grinder or accessories as you still have to order them online but Amazon and Acme Tools have a nice selection of X-Lock grinders and wheels.

Bosch GWX18V-50PCN cordless 18V brushless 4-1/2 – 5″ angle grinder Review

Since I was provided a Bosch X-Lock grinder to test out the mount, I might as well provide a review for it as well. The model I was provided for review is the Bosch GWX18V-50PC cordless 18V Brushless 4-1/2 – 5″ angle grinder. Besides having the brand spanking new X-Lock mount that offers super fast and easy wheel changes that snap in and snap off, this grinder offers a nice assortment of features for a cordless model. Features include a powerful brushless motor for more power and runtime than brushed motor grinders, a slim profile handle that’s easy to grip and wont tire you out as much with long uses. It comes with a single grinding wheel guard and it’s tool-less to rotate which is nice. Something strange and interesting was the lever to rotate the wheel guard is on the body and not the guard. Nothing bad just different. This grinder is also a braking grinder meaning that it’s equipped with an electric brake that stops the wheel in a second or two after the trigger is released. This specific model uses a paddle trigger with safety latch.

This new Bosch 18V grinder is also a bluetooth connectivity READY model, which means that out of the box doesn’t have any slick bluetooth functions or connectivity but has a slot on the side of the tool, which makes it look like a brushed motor grinder, but is actually a slot to install the bluetooth module if you want to add bluetooth. This means that you have to fork out more cash if you want bluetooth. Other brands that offer bluetooth have it built in so I find this strange as to why Bosch makes their “bluetooth” tools “ready” instead of offering it outright as built into the tool. But in the Bosch world this is normal for them as they rather have you buy Bluetooth as a separate purchase.

It only comes as a baretool at the time of writing and includes only the grinder, grinding wheel guard, vibration reduction side handle and cardboard box and paperwork and is priced at 199 which is pricey for a baretool cordless grinder. For example, Makita offers several 18V cordless angle grinders and they have a brushless model as low as 119 baretool which is almost half the price of the Bosch. This Bosch does have the spiffy new X-Lock mount but still priced much higher. Though this Bosch grinder offers additional features like an electric brake and tool-less to rotate wheel guard.

Performance

As far as performance is concerned, I’ve tried out Milwaukee’s and Makita’s cordless brushless models in the past and those were very good performers with lots of power under pressure and don’t bog down easily. The reason I mention those is because I have something to compare this new Bosch model to and after testing it out, I can say that it’s just as strong as the Makita and Milwaukee competition. Under side by side tests with the same cut using the same wheel and material, the Bosch performed just as well as it’s competition meaning strong power to be able to push hard during cuts and grinding without having to worry about the tool bogging down. Just like other brushless cordless grinders, it too offers corded like performance similar to a low power 4-1/2″ corded grinder. I was able to cut small pipe and even a metal stake which was a thick piece of metal and the Bosch GWX18V-50PC handled it like a champ. I also noticed that while it has the same kind of cutting performance power and speed of cut as the Milwaukee M18 Fuel model I tested side by side, I found the Bosch to cut noticeably smoother which made it a more refined tool to work with. Otherwise had the same kind of power as similar brands.

Overall the Bosch GWX18V-50PC cordless 18V brushless grinder is a solid 4-1/2-5″ cordless angle grinder with solid performance and features and not to mention that spiffy new X-Lock mount with crazy fast and easy wheel changes although priced a bit higher than it’s competition in the 4-1/2-5″ cordless brushless angle grinder segment.
