KEENTECH Carbide Tipped 82° Countersink Bit with Depth Stop – 3/8" Dia x 1/8" Drill, 1/4" Shank

Overview

Meet the KEENTECH Carbide Tipped 82° Countersink Bit with Depth Stop, built for woodworkers who value a precise, professional finish. The carbide-tipped blades deliver steady control, while an M2 steel center drill core with a warm gold coating enhances wear resistance. A low-friction depth stop and a secure 1/4" quick-release hex shank enable smooth work flows from start to finish.

The countersink is sized for common screw sizes #6 through #10, making it suitable for a wide range of joinery tasks. Whether you are prepping cabinetry, assembling furniture, or building outdoor structures, this bit is designed to help you achieve consistent results without overdriving or wobble.

Key Benefits

• Carbide-tipped blades offer long life and dependable cutting performance in softwood and hardwood.
• Adjustable depth stop supports both shallow, flush screw seating and deeper countersinks for hiding screws.
• Ball bearing on the depth stop minimizes friction and protects the work surface from scratches.
• Free-spinning, low-friction design helps maintain accuracy and reduces heat buildup during drilling.
• Anti-slip 1/4" quick-release hex shank allows quick, secure bit changes with compatible tools.
• Center drill core made from M2 steel with a gold coating provides improved wear resistance and a longer tool life.

Real-World Applications

• Ideal for cabinets, pet houses, porch swings, bed frames, and other wood projects where precise screw seating matters.
• Pre-drills holes in softwood, hardwood, plywood, MDF, and even certain plastics and aluminum for secure screw placement.
• Depth control helps you maintain uniform countersink depths across multiple holes, reducing post-work polishing.

Usage Tips

1. Set the desired drilling depth with the adjustable stop before starting.
2. Use a steady feed and moderate RPM (around 3,500 for best results).
3. Toggle between shallow and deeper settings as needed without removing the depth stop.
4. Inspect the finish for uniformity; the ball bearing helps minimize surface marks.
