Import 27424 Jobber Length Drill Bit 8mm Hss

Product Description

The IMPORT 27424 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. It measures 8 mm (0.3150 inch) in diameter and features a 118-degree standard point angle suited to a wide range of common materials. The bit is manufactured from high speed steel with an oxide coating that provides basic lubricity and corrosion resistance during cutting operations. Overall length is 4-31/64 inches with a flute length of 3-3/16 inches. The straight-cylindrical shank accepts standard three-jaw drill chucks without modification.

This bit is appropriate for use in hand-held drills, drill presses, and light CNC drilling fixtures in residential, commercial, and light industrial settings. Typical applications include hole-making in sheet metal, conduit, pipe flanges, structural steel, and wood framing. The right-hand spiral flute and web-thinned point reduce thrust requirements and improve chip evacuation, making this bit practical for repetitive production drilling as well as one-off service tasks. It is sold individually with a minimum order quantity of 6 units.

Installation Notes

Secure the shank firmly in the drill chuck and verify concentricity before beginning a drilling operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Always wear eye protection and secure the workpiece before drilling. Follow applicable shop safety codes and equipment manufacturer guidelines when operating drill presses or power hand tools.
