Import 27527 Jobber Drill Bit Wire Size 27 Hss 118 Deg

Product Description

The IMPORT 27527 is a wire-gauge jobber-length drill bit sized to wire size 27, equivalent to 0.1440 inches in decimal. Built from high-speed steel (HSS) with an oxide coating for improved wear resistance and heat reduction during cutting, this bit features a standard 118-degree point angle suited for general-purpose drilling into steel, cast iron, and similar ferrous materials. The straight cylindrical shank seats securely in standard three-jaw chucks. At 3.0 inches overall length with a 1.875-inch flute, this is a compact, everyday jobber-length format. It is sold individually but requires a minimum order of 12 units per purchase.

This bit is designed for general-purpose metalworking applications in maintenance, fabrication, and trade service environments. The right-hand spiral flute with a tapered web and web-thinned point reduces thrust and helps evacuate chips efficiently when drilling ferrous metals such as mild steel and cast iron. It is appropriate for use with handheld drills, drill presses, and milling machines in both shop and field settings. HVAC, plumbing, and electrical professionals will find this size useful for wire-clearance holes and small fastener pilot applications.

Key Features

• Wire size 27 (0.1440 inches) decimal diameter for consistent, repeatable hole sizing
• 118-degree standard point angle for general-purpose drilling into steel and cast iron
• High-speed steel construction provides toughness and heat resistance across a wide range of drilling speeds
• Oxide coating reduces friction and extends cutting edge life
• Web-thinned tapered web reduces drilling thrust and improves chip clearance
• Right-hand regular spiral flute for reliable chip evacuation in through-hole and blind-hole drilling

Compatibility

Designed as a general-purpose jobber drill bit for use in any standard drill chuck accepting a 0.1440-inch straight cylindrical shank, compatible with handheld drills, drill presses, and similar rotary drilling equipment.

Installation Notes

This bit should be installed by securing the straight shank firmly in a properly sized drill chuck before operation. Ensure the workpiece is clamped or secured before drilling to prevent rotation. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain hole quality. Inspect the cutting edges before each use and replace worn bits promptly to avoid work hardening or oversized holes.
