Bench grinders spin too fast for most lapidary things. They create excessive heat that will crack the materials or send them flying across the room. You can get diamond or CBN wheels for a bench grinder, but they're not cheap and still not meant for lapidary work. Answer from DickSnurf on reddit.com

Benchmark Abrasives carries one of the widest ranges of abrasive sanding discs around; we’ve got discs for all tools (angle grinders, die grinders, DA sanders) covering sizes from 2” to 9” with grits (16-400 grit) and grains (aluminum oxide, zirconia, ceramic, silicon carbide, surface conditioning, stripping) to master just about every surface you can imagine.

disc sander on a bench grinder? | BladeForums.com
April 18, 2005 - Feel free to suggest a *safe* way to rig it myself Thanks! edit: starting to think it doesnt exist... i've made my way up the chain from ace all the way to "dewitt tool" and nobody has heard of it, or even a disc sander attachment for a regular hand drill... which i know i've seen before. Click to expand... They do make such a device, but it costs more that it would cost to simply go out and buy a combination sander. Here's the link. http://www.trick-tools.com/Bench_Grinder_Attachments_28?view_all

r/Tools on Reddit: Converting bench grinder into sander?
September 9, 2020 -
I want a bench sander and have a bench grinder with standard discs I have used like once? I have looked for but not found sanding disc conversions. Can you simply remove the grinding disk and attach a sanding disk to the machine and use that? Has anyone done this? I have a no-name bench grinder: https://i.imgur.com/vV3gmyj.jpg
I am pretty handy but it this a no-go? I know I would have to remove the guard and stuff.
Thanks.

November 2, 2022 -
I was starting to get into cutting stones and just wanted to practice using cheaper equipment to get into the practice. I just wanted to see what you all would suggest for grinding wheels and polish that’s not too expensive. Also any recommendations for cheaper necessary tools that will help all suggestions and advice are appreciated.

I just got into egg-shaping and use CBN wheels with a slow-speed (1,750 RPM) bench grinder. 80, 180, 600 and 1,000 grit wheels work well for my use case. Agates may require going through all the wheels, but softer ones can be done in 2. I’m also looking into a belt sander, and may tape together my own sanding belts for grits 1,500 and up.

r/woodworking on Reddit: ?Angle grinder for sanding?
May 18, 2021 -
So I've been serious about woodworking for about 2 years now. I've slowly been adding tools and learning to do things with the tools have. I also watch a lot of woodworking videos. There are a ton of videos (sped up) of people building things on Facebook. It finally dawned on me they were sanding their projects using angle grinders. I had bought an angle grinder years ago for a project and then never used it again. So I picked up some sanding discs and tried it on a refinishing project. Worked great! Why do I never hear anyone talk about this way of sanding? I've done a bunch of research in the last 2 years and and never heard it mentioned. How about it Redditors, who uses an angle grinder for sanding?

The rpm's on an angle grinder are very aggressive leaving a user with very little room for error. But it can certainly be used in certain circumstances

Typically angle grinders are more aggressive then palm/orbital sanders. For what a lot of people do it would be too aggressive for their final project or wanted finish. It’s more of an accuracy vs speed. At least imo.

Convert bench grinder into disc sander? | Woodworking Talk
Would have to figure a way to mount a plywood or mdf plate onto the shaft of the grinder. As well as some method of applying the paper to the plate in a way that it can be changed. ... The right and left threads on either side could be a problem. A better idea might be to get a replacement part from a combo sander, like Craftsman, Jet, etc. and just use a motor shaft, no threads. I made my own that way: http://www.woodworkingtalk.com/f2/homemade-disc-sander-11668/ Grizzly has a 9" cast iron sanding disc: http://cdn4.grizzly.com/manuals/g1014z_m.pdf Part no.

February 12, 2012 - Id get the bench grinder just because its low cost and I'd say almost anything you can get replacement wheels for will work suitably. Basic requirement for Tig tungstens and lathe tool bits and drill bits IMHO. Then you can spend your time kicking over stones looking for a belt and/or disc sander.
