The PRECISION TWIST DRILL 018031 is a high-speed steel (HSS) jobber-length drill bit in size 31. Jobber-length bits offer a balanced combination of flute length and overall length, making them a standard choice for general-purpose drilling across a wide range of materials. The HSS construction provides the hardness and heat resistance needed to cut through harder surfaces without rapid wear. This bit is suited for machinists, maintenance technicians, and trade professionals who need a reliable, correctly sized drill for precision hole-making tasks in metal, plastic, or composite materials.
Size 31 wire gauge drill bits are commonly used in metalworking, HVAC fabrication, plumbing rough-in, and electrical panel work where precise, smaller-diameter holes are required. The jobber-length design fits standard drill chucks and drill presses, making it practical for both bench and field applications. This bit is sold individually, allowing technicians to replace a single worn or broken size without purchasing a full index set.
Designed as a standard jobber-length replacement or supplemental bit for use in any drill or drill press accepting standard round-shank bits in the wire gauge size 31 diameter range.
HSS drill bits should be installed in a properly tightened chuck before operation. Always power down and disconnect the drill or press before changing bits. Use appropriate cutting fluid when drilling ferrous metals to reduce heat buildup and extend bit life. Eye protection is required during all drilling operations per standard shop safety practice.
