Import 22450 Jobber Length Drill Bit 29/64 in Hss

Product Description

The IMPORT 22450 is a jobber-length twist drill bit engineered for general-purpose metal drilling applications. It measures 29/64 inch (0.4531 inch decimal) in diameter with a 5-5/8 inch overall length and a 4-3/16 inch flute length. The bit is manufactured from high speed steel with a gold oxide coating that provides moderate lubricity and surface hardness. A 118-degree split point reduces walking at startup and requires no center punch on most workpieces. The straight-cylindrical shank measures 1/2 inch in diameter, fitting standard keyed and keyless drill chucks. Ideal for machinists, maintenance technicians, and general tradespeople working in metal fabrication or field repair.

This drill bit suits a wide range of general-purpose drilling tasks in mild steel, aluminum, brass, and similar materials. The regular spiral flute clears chips efficiently during through-hole and blind-hole operations. Its web-thinned, tapered web construction reduces cutting thrust, making it well-suited for hand-held drill applications as well as drill press work in shop or field environments. Series 314 classification places it in a standard jobber-length product family appropriate for everyday production and maintenance drilling.

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard keyed or keyless drill chucks accepting a 1/2 inch straight shank, including bench drill presses and handheld corded or cordless drills.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, or qualified tradespeople familiar with rotary drilling equipment. Secure the 1/2 inch shank firmly in the chuck before operation and confirm the workpiece is properly clamped or fixtured. Use appropriate cutting fluid when drilling ferrous metals to manage heat buildup and extend bit life. Inspect the cutting edges for wear before each use and replace the bit if the point shows chipping or excessive dulling.
