Import 22440 Jobber Length Drill Bit 19/64 Inch Hss

Product Description

The IMPORT 22440 is a jobber-length twist drill bit designed for general-purpose hole-making in metal, wood, and plastic. Built from high speed steel with an oxide/gold coating, it provides improved surface hardness and heat resistance compared to uncoated HSS bits. The bit measures 19/64 inches (0.2969 inches) in diameter with an overall length of 4-3/8 inches and a flute length of 3-1/16 inches. A 118-degree split point reduces walking on entry and lowers the thrust required to start a hole. The straight cylindrical shank fits standard drill chucks without modification. Machinists, pipefitters, and general trades installers use this bit for everyday drilling tasks on the job or at a bench.

This drill bit is suited for light to medium-duty drilling in residential and commercial trade work. Common applications include drilling through sheet metal, conduit knockout areas, structural steel, wood framing members, and plastic pipe or fittings. The jobber-length body balances reach and rigidity for handheld drilling and drill press use. The right-hand spiral flute clears chips efficiently during through-hole drilling. General purpose grade makes it a practical everyday consumable for tool bags and service vans.

Installation Notes

This bit is installed by trade professionals including machinists, electricians, plumbers, and HVAC technicians for general drilling tasks. Secure the straight shank fully in the chuck and tighten with the appropriate chuck key before use. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and retire the bit if chipping or excessive wear is observed.
