Teeth Sharpening

[tcalvin48]

Has anyone had their stump grinder teeth sharpen? There seems to be a question of sharpening vs recapping.
Any thoughts?

Not sure if that is hardened metal, which it probably is, the only way you would be able to sharpen is with a cutting torch, and then you would lose your metal temper. I attempted to sharpen a trencher teeth and that just destroyed the grinding blades, hardened metal is impressive.

I am sure they can be re-sharpened with an appropriate grinder but it may be easier and more cost/time effective to simply replace them.

Matters on the type of teeth, there are quite a few.
Also some are carbide tipped, if there is enough of the carbide left a good saw shop or machine shop can sharpen them.
In some cases it's much cheaper to just replace them than it is to have them sharpened.

This place seems to have a good price. All my teeth are still like new. So I have never tried this place but it might be worth a shot...

Send them to Sidecar Flip. He does that kind work.

I had some stumps ground and the guy asked if the teeth could be sharpened in my tool & die shop. They were carbide tipped and were worn to the point that sharpening would be impossible to get them right. I told him to just buy new rather than have low performance resharpened teeth.

Not really, even re-tipping is half the price of a new tooth.

Jeff's is one of the places I'm thinking about for re-sharpening. My concern is from a conversation with Scott at Wit-son/Gabdon (who makes teeth). He said the heat of re-sharpening would destroy the bond the carbide tooth has with the steel part of the tooth, that is, better to re-tip than re-sharpen. But re-tipping is about twice the price of sharpening.

I find that "heat will destroy the bond" idea hard to swallow. Regrinding bonded carbide tipped cutting tools is standard practice in the metal cutting world. There are plenty of ways to control the heat if need be. I would have a few of your teeth sharpened and test that theory out before accepting it at face value.

Thanks Dan, that's sorta what I thought. I'll call Jeff's sometime this week and talk to him.

Also all the carbide tools I have ever used the carbide is brazed to the steel. No way grinding is going to get the steel hot enough to melt the brazed tip.

Exactly. The teeth on my Woodland Mills grinder appear to have conventional brazed carbide tips.
