Oops! Blunt a tool the easy way.

 19226 forum posts 749 photos 86 articles | Just spotted this and thought I'd share a pic. This is what happens when you are in a hurry to get rid of some material and forget to change to a carbide tip. It would have helped if I'd made a better job of grinding the top as well... must have been in a REAL hurry! Neil

19226 forum posts 749 photos 86 articles | Hi Andrew, A 180 degree turn would mean extra grinding, because the angling of the toolbit is about 10 degrees, the top needs to be ground at about 20 degrees (that one isn't really ground at enough of an angle). Indeed, I may remake this (version 4...) with 12 degree clearance angles. Neil |
