About Counterbores
Create flat-bottomed holes, so your screw heads sit flush, recessed, or slightly raised.
Drill-Point Counterbore Sets
![]() |
Skip a step when installing screws of various thread diameters in metal. With a sharp point on the tip, these counterbores drill a pilot hole topped with a flat recess for the screw head. That's faster and more accurate than switching to a counterbore in between passes with your drill bit.
High-Speed Steel—Durable and wear resistant, these counterbores make accurate cuts in most materials without chipping or cracking.
