Import 22428 Jobber Length Drill Bit 7/64 Inch Hss

Product Description

The IMPORT 22428 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel (HSS) with a gold oxide coating, this bit delivers adequate heat resistance and lubricity for everyday drilling tasks. The 7/64 inch diameter (0.1094 inch decimal) pairs with a 118-degree split point for self-centering starts without a center punch. The right-hand spiral flute clears chips efficiently, and the straight-cylindrical shank fits standard drill chucks without modification. Machinists, pipefitters, and general trade technicians keep bits like this on hand for light-duty fastener, pilot, and clearance hole work.

This bit suits residential and light commercial applications where frequent, repeatable small-diameter holes are needed. Typical scenarios include pilot holes for self-tapping screws, clearance holes for 8-32 or 10-24 fasteners, sheet metal penetrations, and HVAC or plumbing bracket installations. At 2-5/8 inches overall length with a 1-1/2 inch flute length, it fits standard three-jaw drill chucks on cordless drills, drill presses, and hand braces. The tapered web configuration and web-thinned geometry reduce thrust required at the cutting tip, which is useful when working in confined spaces or with thinner stock.

Key Features

• 7/64 inch diameter (0.1094 inch decimal) for consistent, close-tolerance hole sizing
• 118-degree split point for self-centering entry without a center punch
• High speed steel construction with gold oxide coating for heat resistance and reduced friction
• Right-hand cut spiral flute with regular helix for positive chip evacuation
• Web-thinned, tapered web geometry reduces drilling thrust and minimizes bit walking
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks accepting straight-cylindrical shanks in the 7/64 inch size range.

Installation Notes

Install the bit firmly into a drill chuck and tighten with a chuck key before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain edge geometry. Operate at a spindle speed appropriate for the material and bit diameter — smaller diameters generally require higher RPM with lower feed pressure. Inspect the cutting edges before each use and replace any bit showing chipping, discoloration from overheating, or loss of point geometry.
