Import 22358 Jobber Drill Bit 9/64 Inch Hss Oxide

Product Description

The IMPORT 22358 is a general-purpose jobber-length drill bit designed for precision drilling in metal, wood, and plastic. It features a 9/64 inch (0.1406 inch decimal) diameter with a standard 118-degree point angle ground from high speed steel and finished with a black oxide coating for added corrosion resistance and reduced friction. The spiral flute geometry is a regular right-hand configuration, pulling chips out of the hole efficiently during operation. Overall length is 2-7/8 inches with a flute length of 1-3/4 inches. The straight-cylindrical shank seats securely in standard keyed or keyless drill chucks across a wide range of tools.

This bit is suited for general maintenance, fabrication, and light production drilling tasks across HVAC, plumbing, electrical, and mechanical trades. It handles the day-to-day hole-making work found in sheet metal layouts, conduit runs, structural framing, and equipment mounting. The web-thinned tapered web design reduces thrust required at breakthrough, making it practical for hand-held drilling in tight or overhead installations common in field service work.

Key Features

• 9/64 inch diameter with 0.1406 inch decimal equivalent for precision sizing
• 118-degree standard point angle for general-purpose drilling across multiple materials
• High speed steel construction provides durability in repeated use applications
• Black oxide coating reduces friction and provides mild corrosion resistance
• Web-thinned tapered web lowers thrust load and improves chip clearance
• Straight-cylindrical shank compatible with standard drill chucks

Compatibility

Designed as a general-purpose replacement or stock drill bit for use in standard keyed and keyless drill chucks accepting straight-cylindrical shanks in the 9/64 inch size range.

Installation Notes

Installation is performed by machinists, maintenance technicians, and licensed trade professionals using hand drills, drill presses, or magnetic-base drills. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or otherwise restrained. Use appropriate cutting fluid when drilling steel to extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
