Import 22452 Jobber Length Drill Bit 31/64 Inch Hss

Product Description

The IMPORT 22452 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. It features a 31/64 inch (0.4844 inch) diameter and is manufactured from high speed steel with an oxide/gold coating that improves surface hardness and lubricity. The 118-degree split point reduces walking on entry and lowers the thrust needed to start a hole. The right-hand spiral flute evacuates chips efficiently during through-drilling. This bit is a standard stock item used by machinists, pipefitters, electricians, and HVAC technicians for drilling pilot and through-holes in sheet metal, structural steel, and pipe.

This jobber-length drill bit suits a wide range of trade and light industrial applications. The straight cylindrical shank accepts standard three-jaw chucks on drill presses, hand drills, and magnetic base drills. The 5-7/8 inch overall length gives adequate reach for most panel, sheet, and structural work without sacrificing rigidity. The web-thinned, tapered web geometry reduces cutting torque on larger-diameter work, making this bit appropriate for repeated use in production or service environments where a 31/64 inch hole size is required.

Key Features

• 31/64 inch diameter (0.4844 inch decimal) for precise hole sizing
• 118-degree split point reduces bit walking and lowers entry thrust
• High speed steel construction with oxide/gold coating for improved wear resistance
• Right-hand regular spiral flute for efficient chip evacuation
• Web-thinned tapered web reduces cutting torque
• Straight cylindrical shank fits standard three-jaw drill chucks

Compatibility

Designed as a general-purpose replacement or stock drill bit for any application requiring a 31/64 inch diameter jobber-length drill bit with a straight cylindrical shank in the 0.4000 to 0.5000 inch decimal size range.

Installation Notes

Install the shank fully into a properly sized three-jaw chuck and tighten securely before drilling. Always power down and lock out the drill press or tool before changing bits. Use appropriate cutting fluid when drilling hardened steel or stainless to extend bit life and reduce heat buildup. Wear eye protection and secure the workpiece to prevent rotation during drilling.
