RE: [gingery_machines] new article available: Drill, Tap, and Counterbore

 

Steve,

Interesting modification to a drill but IMHO, beyond what a person new to
the hobby can handle. However, it would make for an interesting new article
:-))

Hi guys!

Nice info you got there...perhaps Ron is correct not to use mill
cutters on the spindle chuck. My approach is different, I learnt this
trick from my training school long ago. I would grind my drill bit
almost flat. With a 0.5mm normal drill bits slightly bigger, I drill a
shallow step as a guide and use this flat drill to counterbore and
c'sink or debur with a hand-drill.

If the c'sunk hole is deep, I would use the ratchet brace like the pdf file.
