Bench grinder wheel for brad point sharpening
Im finally going to try and learn elanjacob's method of sharpening brad points and looking at a new grinder + wheel.
I managed to find this 6mm wide wheel but the arbor size is huge
Norton Grinding Wheel Med/Fine Toolroom 150 x 6 x 31.75mm
Is there a way to adapt this to a standard bench grinder? (I believe most grinders are M12)

What size bits are you sharpening, a 6mm wide bit means you cant sharpen anything bigger then 6mm.
I've never tried it but is there any reason you couldnt use a linisher?

Same method for regular twist drills as Elan said. Just move them across the face.

I actually like to use the side of the wheel for twist bits, I just found it more comfortable and easier to see.

The search function is hit and miss, if you don't use the exact terms it won't find what you want.

Interestingly, where I used to work, we were forbidden to grind using the side of the wheel unless the wheel manufacturer permitted it. Generally special wheels which we never had. The Govt followed Work Safe Australia rules to the letter.

Oh I know you're not supposed to use the side, but it was all fairly small bits and very light pressure. Lots of things happen in small shops (and plenty of large ones too) that aren't exactly "by the book"...

I just noticed that the grinding wheel I linked to is 60 grit - is that too rough?

We used to get 80, but they were discontinued so we had to get 60. There's a visual difference, but doesn't matter functionally
