Import 27406 Jobber Drill Bit 3.00 Mm Hss Oxide

Product Description

The IMPORT 27406 is a general-purpose jobber-length drill bit designed for metal, wood, and plastic drilling applications in light fabrication and maintenance work. Built from high speed steel with an oxide finish, it offers basic heat and corrosion resistance suited for intermittent production use. The bit features an 118-degree standard point angle, a right-hand spiral flute with regular helix, and a straight-cylindrical shank for use in standard drill chucks and drill presses. Overall length is 2-3/4 inches with a flute length of 1-39/64 inches. The web is thinned and tapered to reduce entry resistance and improve chip evacuation on breakthrough.

This drill bit is used in general shop, field maintenance, HVAC, plumbing rough-in, and light electrical work where a small-diameter pilot or clearance hole is needed. With a diameter of 3.00 mm (0.1181 inches), it falls in the 0.1000 to 0.1500 inch size range and is appropriate wherever metric-sized holes are called out on fabrication drawings or installation specs. Sold individually, it is sized for use in portable drills, drill presses, and bench-mounted equipment. Trade professionals typically keep this size on hand for anchor pilot holes, wire clearance bores, and sheet metal work.

Key Features

• 3.00 mm (0.1181 inch) diameter for metric hole sizing in fabrication and installation work
• High speed steel construction with oxide coating for basic heat resistance
• 118-degree standard point angle for general-purpose entry on common materials
• Right-hand spiral flute with regular helix for consistent chip removal
• Web-thinned, tapered web design reduces cutting resistance at breakthrough
• Straight-cylindrical shank fits standard 3-jaw chucks without adapters

Compatibility

Designed as a general-purpose replacement jobber drill bit fitting standard 3-jaw chucks and drill press collets that accept straight-cylindrical shanks in the 0.1181 inch diameter range.

Installation Notes

Install in a properly sized drill chuck and tighten securely before use. Always wear appropriate eye protection when drilling. Use cutting fluid on ferrous metals to extend bit life and reduce heat buildup. Inspect the bit for chipping or wear before each use and discard bits that show visible damage to the cutting edge.
