Import 27429 Jobber Drill Bit 10 Mm Hss Oxide

Product Description

The IMPORT 27429 is a general-purpose jobber-length drill bit designed for drilling in metal, wood, and plastics. It features a 10.00 mm (0.3937 inch) diameter, a standard 118-degree point angle, and is manufactured from high speed steel with an oxide coating to reduce friction and extend tool life. The spiral flute geometry promotes efficient chip evacuation, and the web-thinned, tapered web configuration reduces thrust required at the point. Right-hand cutting direction suits the vast majority of standard drilling operations. This bit is a reliable shop staple for machinists, maintenance technicians, and fabricators.

This drill bit is suited for general-purpose drilling in light industrial, maintenance, and fabrication environments. The straight-cylindrical shank fits standard three-jaw drill chucks found on bench drills, drill presses, and hand drills. With an overall length of 5-1/8 inches and a flute length of 3-47/64 inches, it offers the reach and chip clearance typical of jobber-length tooling used in everyday production and repair work.

Key Features

• 10.00 mm (0.3937 inch) diameter for precise, consistent hole sizing
• 118-degree standard point angle for versatile material compatibility
• High speed steel construction for durability in general-purpose applications
• Oxide coating reduces friction and helps resist corrosion
• Web-thinned tapered web reduces drill thrust and improves point penetration
• Spiral flute with right-hand cutting direction for standard chuck compatibility

Compatibility

Designed as a general-purpose jobber drill bit compatible with any standard three-jaw drill chuck accepting a 0.3937 inch straight-cylindrical shank, suitable for bench drills, drill presses, and handheld power drills.

Installation Notes

Install and remove drill bits only with the drill fully powered off and, on drill presses, the spindle at rest. Secure the straight-cylindrical shank firmly in a properly sized chuck and tighten with a chuck key before operation. Use appropriate cutting fluid or coolant when drilling metal to preserve edge life. Always wear eye protection and secure the workpiece before drilling.
