Grinding discs to sharpen stumpgrinder teeth, i usually take mine out and bench grind them this would be quicker.

I was thinking of getting one, just for touching up on site and keeping an edge, if it were touched up every so often it would be a quick job.

 

I tend to end up taking them off and spending ages grinding them because I've left them too long and they are really rounded off.

To sharpen grinder teeth properly they should only be ground on the flat front face, not round the sides.

 

I know this isn't always possible because sometimes they are left a long time, get too rounded and you'd have togrind half the tungsten away to get a sharp edge.

 

But if you have one of these discs you could just keep touching them up so they don't get rounded and keep sharp.

 

I was grinding the other week and it flew through the first stump, then must have hit a stone which took the edge off, it was then painful doing the rest with slightly dulled teeth.

You sure about that? I always thought (think I read somewhere) that you should only sharpen the sides. I usually sharpen the flat face and then touch the sides up to get a nice edge.

It's common practice to sharpen the sides and round the top but it's not right.

 

If you have them retipped (which we don't anymore, we throw them,) you will have ground away part of the steel seat which holds the new carbide tip.

 

On wood working saw blades, only the face is ground
