Import 27434 Jobber Length Drill Bit 12.5 Mm Hss

Product Description

The IMPORT 27434 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel with an oxide coating, this bit handles everyday production and maintenance drilling where consistent performance matters. The 118-degree standard point geometry suits a wide range of common materials. At 12.5 mm (0.4921 inches) in diameter with an overall length of 5-63/64 inches (152 mm), it fits standard drill chucks and magnetic drill press setups used in fabrication and mechanical trade work. The straight-cylindrical shank seats securely in three-jaw chucks without slipping under load.

This bit is suited for trade professionals and maintenance technicians working in HVAC, plumbing, electrical, and general mechanical service. Typical applications include drilling clearance holes, pilot holes, and through-holes in mild steel brackets, sheet metal, conduit hangers, and similar structural components. The regular spiral flute promotes chip evacuation during through-drilling, and the web-thinned, tapered web construction reduces feed pressure needed to start the cut. Each package contains one bit. Minimum order quantity is 6 units.

Key Features

• Right-hand cut compatible with all standard drill presses, hand drills, and magnetic base drills

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw chuck accepting a 0.4921-inch straight-cylindrical shank, including benchtop drill presses, hand drills, and magnetic base drills commonly used in trade and maintenance applications.

Installation Notes

A licensed or qualified trade technician should secure the bit firmly in the chuck before operation and verify chuck key removal prior to starting the drill. Always wear appropriate eye protection when drilling metal or composite materials. Secure the workpiece with a clamp or vise — never hold it freehand. For drilling into harder steels, use cutting fluid to extend bit life and reduce heat buildup at the cutting edge.
