Important Product Questions
Which pilot drill comes with this countersink?
The #8 countersink uses a 11/64 in pilot drill. Confirm the screw and workpiece requirements before drilling.
How do I adjust the pilot depth?
Disconnect the drill, use a 1/8 in hex key to adjust the exposed bit length, then secure the adjustment before making a test hole.
Is the quarter-inch shank an impact rating?
No. The 1/4 in quick-change hex describes the connection. This countersink is specified for drill/drivers; do not assume impact-driver compatibility from shank shape.
