Getting More From Your Angle Grinder




About: Just a fellow who want's to learn new tricks and skills.


I have used angle grinder over twenty years.

I had allready forgot how difficult it was to use at the beginning.

Then i heard people saying that its too difficult to cut with it..

That started me to think about how to improve its handling, also i wanted to get more from it.

As it think, it can be used as a bench grinder too, and with suitable blade, it works as a circular saw, or with the right attachment its a great tool for cutting even big pipes, straight and easily.

Easy version starts from the step 1, improvements from the step 8. Attcahments for grinding and pipe cutting from the step 10

This is my simple and easy prototype for that problem, improvements makes it little more difficult.

Video tutorials shows the process.

Used tools:

Angle grinder




3mm steel plate

40 x 40 x 5mm square tubing

Piece of 30 x 30 x 3 L-profile

80mm long M12 screw and M12 nut

Two M10 screws, spring washers, and one M10 nut

Step 1: Cut the Parts..

Cut the parts to the desired size.

Sand edges smooth, and round the corners.

Step 2: Easy Mount for the Angle Grinder..

My angle grinder, as usual had threads for the handle in both sides.

Also, its very usual that those threads are little tilted, instead of pointing directly up and down.

So, when you bolt plates to them, Plates make kind of V-shape. That shape makes this simple structure firm enough, no need for extra connections.

Just line those plates and the M12 screw with the angle grinder, before welding. Keep cutting disc on its place and use right angle for lining.

Step 3: Make Extra Position for Handle..

Made a hole, big enough that thread of the handle fits through it. (10mm)

Cut it to shape, and weld nut behind the hole. ( M10 )

Tack weld it. Place and shape it so that you still manage to push "disc lock"- button. So, you can change new disc without need to remove your attachment.

Step 4: Bottom Plate..

I made a little bend for the front of the bottom plate, it helps it to slide easier.

Then made 8mm holes for the "back stop", that's the piece of 30 x 30 x 3mm L- profile, mentioned earlier.

Connected it with butt welds. That way bottom plate stays straight, and the result looks nicer.

Step 5: Connecting to the Bottom..

To connect these two parts together.

I made a simple "hinge" from a piece of 40 x 40 x 5mm square tubing.

Drilled 12mm hole to the center of the side. Made it through both sides. ( M12 screw goes trough it )

After drilling i cut it to desired length. ( 35mm )

Then i weld it to the bottom plate.

Step 6: Finishing..

Finally i grinded away some material from the " back stop ", so that angle grinder fits to move lower.

Cleaned welds with steelbrush and finally painted it black.

Step 7: How It Works??

It works as a little chop saw..

Its easier to handle when cutting freehanded..

Its more easier to use, when cutting using guide..

And of course, its easy to mount, just clamp it to the table..

And.. when you remove bottom plate, you can use extra position for the handle, to get firm grip for heavier working.

Thanks for watching!

Stay tuned...

Step 8: Improvements...

Some improvements. I'll update this section until its finally "done".

1. Another option for the handle.

2. Screw that locks the angle grinder to the stand so that it doesn't move sideways when tightening screw is loose. Good when using as a chop saw. It also secures straight cuts if tightening screw opens itself.

3. Quick tightening action with simple thump screw, made from M12 nut and piece of flat bar.

Down its loose. Up, its tightened.

4. Bigger guard for safer use.

Step 9: Improvements Continued..

1. add supports that guides angle grinder to the same line with the base, faster and easier assembly.

2. Optional support wheel, helps with wood carving and grinding.

I use Graff speedcutter discs wich are made to wood cutting and shaping with angle grinder, max rpm is 12.000.

Step 10: Attacments...

Simple grinding rest from 2mm steel.

And pipe cutting attachment. This is a prototype wich can be used with pipes between 50-125mm diameter.

Its intented to be used in jobsite works, when you need to have accurate joints. For example: When you weld pipes trough from the one side, you need precise cap to get acceptable root.

Actual final version will be for pipes over 200mm diameter.

Video shows the process:

Step 11: Woodworking..

Last video is from woodworking with it.

Works nicely with dados, grooves, and of course with a simple attachment..

Its a biscuit jointer too..

Step 12: Invention...


The actual "invention" is very simple. All those attachments shown, could be much easier to install..

If tool manufactures would add this simple lug to their angle grinders.

Picture is bad, shape and size just something.. But i think that would be best location for the extra lug.

Thanks for watching..

And vote if you liked the idea..

What a fantastic idea, the development of the various accessories is truly inspired . . . in response to your "Step 12: Invention . . ." I have created a 3D printed part that effectively provides a ready made "Easy Mount" for those without the welding skills and/or tools to replicate your approach.

The 3D printed Easy Mount ( ) is fitted to the angle grinder with two M10x25mm bolts inserted into the two existing threaded holes (usually used for the handle). The Mount then provides a forward facing mount point perpendicular to the disk in the form of two M10 captive nuts vertically spaced 25mm apart. These two M10 captive nuts provide the means for attaching accessories to the front of the angle grinder with short or long M10 bolts as required.

Full access is provided to the spindle lock and the guard adjuster when the bracket is in place.

This is awesome! I don't have the capabilities to do the welding though — would you sell one of these?

i want to make it but the dimension for the base plate please.

thanks for your project.

215mm x 105mm x 3mm

Bend at the front end, 20mm distance from the front end. Square tubing that works as a hinge is placed to 22mm distance from the front edge.

I have scaled this plate in another video and looks like 220x100 x3mm ,please clarify..

This is great :)
Can easily cost lot of money and space on a chop saw.

Following closely I intend to try to follow the way you have shown. The problem is the Bosch grinder 'MAKITA grinder 9500N' there are no handle holes in it. I do hope you can come up a way so I could do it. Thanks.

Hi Tuomas, thanks for your project, I find it very interesting. I have a couple of question for you:

I see you use a drill press with a speed controller attached to it. Could you please provide details on its brand/model etc?

Also, you use a sheet bender to bend metal. It is probably home made. I'd like details on such bender, any link to project files?

And last, since I'm in the process of replacing my angle grinder, any suggestions on a decent one for hobbyist use? Bosch may be? ;-)

Thank you - regards!

Drill is Evolution Evomag50 magnetic drill.

You can find my bending brake from here:

I have liked blue Bosch grinders. Those are slim and nice to use. Dewalt has also slim models, but the price is higher. I have been happy with Bosch pro- line models.
