Century Drill Tool Co Inc 22315 Hss Drill Bit 15/64 in 3pk

Product Description

The CENTURY DRILL TOOL CO INC 22315 is a 15/64-inch brite-finish high speed steel (HSS) drill bit sold in a 3-piece pack. Designed for general-purpose drilling in wood, metal, and plastic, it features a 135-degree split-point tip that self-centers on contact, eliminating the need for a center punch. The tip penetrates faster and requires less applied pressure than conventional 118-degree points. Ground flats on the shank seat securely in both keyed and keyless chucks, preventing slippage during operation. Weighing 0.12 pounds for the pack, this bit is a compact, everyday shop and field tool used by HVAC techs, plumbers, electricians, and general maintenance professionals.

The 22315 is suited for light to medium drilling tasks across a range of materials encountered in trade work, including metal brackets, wood framing members, and plastic enclosures or junction boxes. The 15/64-inch diameter is a common sizing for pilot holes and clearance holes used when fastening hardware in mechanical and electrical installations. The 3-piece pack provides immediate backup in high-use environments where bit wear or breakage is a routine consideration on the job site.

Installation Notes

Installation and use should follow standard drilling safety practices applicable to the trade. Secure the workpiece before drilling and confirm the chuck is fully tightened onto the ground flats of the shank before applying power. When drilling metal, use an appropriate cutting fluid to extend bit life and reduce heat buildup. Inspect the bit for tip wear or damage before each use and replace when the point shows visible rounding or the cut rate slows significantly.
