PCB pad cutter

<< < (5/5)

Mike K:
Other view of his bit:

 

vtsteam:
That doesn't show any of the angles. An end view would show the radial angle.

vtsteam:
Here's what I'm talking about. The end clearance angle is exaggerated because it recedes in the photo. The honed  flatting of the cutting edge is also normally done to conventional drill bits when drilling copper based metals.

Mike K:
I honed the cutter some more and made a board.  Still getting some tearout and raised burr edges.

 

Couldn't get a good closeup of the cutter.  I'll try again with a small tripod and better lighting.  Am now very impressed with AndyDaviesByTheSea results.
