Heavy Duty Single Piece 82 Degree HSS Countersink Bit
✔️ 6 flute HSS tool provides accurate hole prep for standard fasteners

This heavy duty single unit countersink removes material efficiently when you need clean 82 degree seating for screws and bolts. You will typically run this straight shank bit in drill presses or handheld power tools to prepare wood, aluminum, and mild steel for fastener installation.

✅ 1.25 inch face diameter spreads load evenly across recessed screw heads
✅ 82 degree included angle matches most standard fastener manufacturers
✅ 3 3/8 inch overall length keeps cutting edges close to the spindle
✅ 3 4 inch round shank fits common drill chucks securely without wobbling

💡 How do I properly set up a heavy duty 6 flute HSS countersink for tight tolerances?
The trick involves matching your feed pressure to the flute count while keeping your drill press steady.
This handy routine stops wandering bits and extends cutter life on aluminum and steel alike.
- Clamp the 3/4 inch shank firmly into your chuck to eliminate lateral shake during initial passes
- Lower the 82 degree cutting face slowly until it meets the workpiece without forcing the motor
- Maintain a moderate RPM so the round steel shaft transfers torque directly into clean angled recesses
- Withdraw the cutter carefully after each pass to clear swarf and prevent cross threading later on
