Import BDNA-KP65027 Jobber Drill Bit 21/64 in Hss

Product Description

The IMPORT BDNA-KP65027 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. It measures 21/64 inches (0.3281 inches) in diameter with an overall length of 4-5/8 inches and a flute length of 3-5/16 inches. The bit is manufactured from high speed steel with a black oxide coating that reduces friction and provides basic corrosion resistance. The 118-degree standard point angle suits a wide range of common materials. Right-hand spiral flute geometry evacuates chips efficiently during through-hole and blind-hole drilling operations. The straight-cylindrical shank fits standard three-jaw chucks on drill presses and handheld power drills.

This bit is suited for maintenance, fabrication, and light production drilling tasks in trade and industrial environments. HVAC technicians, plumbers, electricians, and general contractors reach for jobber-length bits when drilling sheet metal, conduit knockouts, pipe flanges, mounting holes, and structural members. The regular spiral flute and tapered web with web thinning help the bit start cleanly and reduce walking on flat surfaces. At 21/64 inches, the diameter is commonly used for clearance holes and pilot holes in a variety of fastener and fitting applications.

Installation Notes

Secure the shank fully in the chuck and tighten with a chuck key before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life. Always wear eye protection and follow applicable workplace safety requirements when operating drilling equipment.
