Amana Tool Carbide-Tipped 82° Countersink Drill Bit with Straight Pilot Bit, No-Mar Ball-Bearing Depth Stop and 1/4'' Hex Shank, 3/8'' Main x 5/64'' Pilot

Amana's high-performance countersink bits feature a heavy-duty ball-bearing depth-stop that eliminates scratching and burning when it contacts the surface. One plunge drills a pilot hole and corresponding countersink for the screw head. The user-friendly design enables full adjustment of the pilot bit length and depth of the countersink, without the need for disassembly. Each bit has a generous open space to allow for chip evacuation.

Features:

• Quick release 1/4'' hex shank for easy bit changes
• Includes fully-ground straight pilot bit (slow-spiral M2 HSS), which many prefer since hole depth is not as critical as it is with tapered bits
• Excellent for drilling hardwoods, softwoods, plywood, particleboard, MDF and composites
