Important Product Questions
Which countersinks and pilot sizes are included?
The set contains #6 with a 9/64 in bit, #8 with an 11/64 in bit, and #10 with a 3/16 in bit.
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.
