He Machines Drill Bits
 |
He used his lathe to convert two large drill bits with a Morse taper to an R-8 shank. "A lot of today's drill presses don't have enough vertical clearance to use Morse taper adapters with a big drill. For example, I have a Bridgeport mill that doesn't have thrust bearings in it and is made for milling only. As a result, I can't crank the drill press up high enough to put all my adapters on. If I do, the sleeves will hit the table.
"So instead I chucked the drill bit into my lathe and machined it down to fit the R-8 spindle. Do the machining before you saw off the Morse taper flat. You then will have a counter sink hole for the tail stock on your lathe."
