Bench grinder wheel for brad point sharpening

[qwertyu]

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 (https://www.aimsindustrial.com.au/norton-grinding-wheel-med-fine-toolroom-150-x-6-x)

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?

You just move the bit across the face of the wheel, same way you sharpen a 60mm plane blade on a 25mm wheel. I had no trouble sharpening large bits on it

yep i mis read the title and was thinking of regular twist bits

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.

Is there a link or a thread on that. I did a quick search and can't find any article?

Thanks for that, no idea why the search function did not find it?

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"...:rolleyes:

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

[elanjacobs]

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
