Quick question: What is the best way to do rest machining after using a twist drill.
Example:
I create a hole .475" in diameter, .5 deep.
I first drill it with a 7/16 drill bit and then I want to go in with a say a 1/4 end mill to helical down to clear out the bottom (twist drill tip) and then spiral out to the hole finish size.
I end up with a flat bottom hole at the correct size.
Thanks,
Richard
