Hello friends, does anyone have experience in building (DIY) the trepan tool (drill)? |
| WeldingRod:
I've got a val-cut and I've also ground tools to do it. VERY useful! Do you need photos? Sent from my SM-G892A using Tapatalk |

Here's a few pictures of a carbide trepanning insert , they may help with the cutting geometry. |

Bill, does that tool have a tendency to dive towards the centre of the hole ? Quite aggressive rakes on the tip, something I should really have a play with, what are the tip dimensions hard to judge scale from the pictures. |
