I bought a set of ten tc engraving cutters from China , and have broken the tips from five so far , I made a simple jig to sharpen and put a relife angle on them , 1/2" Whit tread as it is turned in it puts the relife on , and any cutting angle is easely set , these are 20 degrees I hope these will last longer . |

A very neat idea using a coarse thread to create the relief - I must remember that one :thumbup: |

I'm looking over my copy of the Norman Tinker drawings and would be delighted to see more of it. Perhaps you could oblige? Thank You Norm |

Do not try to use these cutters as is from China they are far too sharp You need to take a single swipe with a diamond slip angled back a couple of degrees and sideways a couple so you have less of a point, more the flat you get with your 12 degree attachment TBH I still prefer HSS for fine work, far more forgiving |

I was reliving the tip John but anything more than 0.2mm cut on brass and the tip went , 20 degrees gives a cleaner cut and the tip is still sharp , I will expriment further but still calling it a sucess . |
