Professional Replacement Pocket Hole Twist Step Drill Bit (71933)
Zero-Splinter Axial Boring for High-Precision Joinery
The POWERTEC 71933 is a professional-grade 1/4" Hex Shank Pocket Hole Drill Bit, specifically precision-engineered to eliminate the entry-burrs and "depth-drift" common in standard drilling. This specialized step bit is the definitive choice for woodworkers who need to execute 100% efficient axial boring for hidden screw joinery. Featuring premium High-Speed Steel (HSS) construction, the 71933 series provides the structural hardness and thermal stability required to bore through hardwoods and softwoods with surgical accuracy.
Constructed with a two-tier architectural logic, this bit facilitate a Laminar Cutting Path. The 3/8" main body creates the pocket for the screw head, while the pilot tip prepares the axial path for the screw shank. The included depth stop collar ensures a stable mechanical center of gravity axial to the jig, providing the mechanical security required for high-stakes professional production. Whether you are building face frames or custom furniture, this bit delivers the mechanical durability and mathematically precise depth required for showroom-quality results.
- Elite Step-Bit Logic: Integrated pilot and pocket geometry ensures a 100% efficient axial seat for all standard pocket screws.
- Quick-Change Hex Shank: 1/4" hex architecture provides a stable mechanical bond with impact drivers and standard drill chucks.
- Surgical Depth Control: Heavy-duty stop collar prevents "over-boring" axial to the material, protecting your workpieces from blowouts.
- Industrial HSS Build: Hardened high-speed steel resists heat-buildup axial to the flutes and survives the abrasive nature of wood resins.
- Clog-Resistant Flutes: Engineered for 100% efficient chip ejection, preventing the "bit-burn" failure mode during high-speed production.
