Import -22380-B Jobber Drill Bit 31/64 Inch Hss

Product Description

The IMPORT -22380-B is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with a bright uncoated finish, it delivers reliable performance in standard production and maintenance applications. The 118-degree standard point angle suits most common materials and allows easy center-starting without a pilot hole. At 5-7/8 inches overall length with a 4-3/8 inch flute length, this bit fits a wide range of handheld and bench-mounted drilling equipment. The straight-cylindrical shank accepts standard drill chucks without adapters. Web thinning reduces thrust and improves chip clearance at the cutting tip.

This drill bit is suited for use by machinists, maintenance technicians, plumbers, electricians, and HVAC installers who need a reliable fractional-size bit for everyday hole-making tasks. The 31/64 inch diameter is commonly used for bolt clearance holes, conduit knockouts, and pre-drilling before tapping or reaming. It is sold individually but requires a minimum order of 6 units per purchase.

Installation Notes

This bit is installed by a machinist, technician, or tradesperson into any standard drill chuck capable of accepting a straight-cylindrical shank. Secure the shank fully in the chuck before operation and verify the chuck key is removed before starting the machine. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and reduce heat. Inspect the cutting edges for wear before each use and replace if chipping or dulling is evident.
