ZeroMark Countersink Bits

The Most Advanced System For Drilling Countersinks and Plug Holes

Unique Features Provide Unequaled Level of Drilling Accuracy and Fine Finish

Countersink Sleeve and Drill Bit are independently adjustable

• The laser enscribed scale on the Countersink Sleeve, in both metric and English, allows countersink depth to be set in minute measurements.
• The depth of the drilled hole is adjustable by changing the exposed length of the Drill Bit.  A flat on the drill bit shank allows the allen screw to seat against a solid foundation preventing any slippage of the bit during tightening or drilling.
• Non-metal Countersink Sleeve stops spinning upon touching the work piece, preventing any marring of the work piece surface

Drill Bit has elongated “starter” point facilitating a more accurate entry of each hole drilled.  Bits work effectively at up to 1400 rpms.
