Carbide Tipped CNC Countersink Bits

Carbide Tipped CNC Countersink Bits

Drilling countersinks with these bits on the CNC machine is a great way to save time and have your pieces look great every time! With the adjustable depth drill bit you can adjust them for whatever size material you’re working with. They are best used with a drilling toolpath, utilizing the peck drill option at .25" per pass with a .125" retract height.

For best results run at 3,000 RPM with a 30 IPM (Inches Per Minute) plunge rate. No feed rate needs to be set with these as they only move up and down with the Z axis, not side to side. If your software doesn’t allow a 0 feed rate, you can enter 1 IPM (Inch Per Minute) in the feed rate as a placeholder.

For countersinks with 1/4" round shank, use 1/4" spring collet.

For countersinks with 5/16" round shank, use 7-8mm spring collet.

For countersinks with 3/8" round shank, use 9-10mm spring collet.
