Import -22400-J Jobber Drill Bit Letter J Hss Oxide

Product Description

The IMPORT -22400-J is a jobber-length drill bit sized to letter J (0.2770 inch decimal equivalent), designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with an oxide coating, this bit delivers adequate wear resistance for production and maintenance drilling applications. The 118-degree standard point angle suits a wide range of common materials, and the web-thinned tip reduces thrust and improves center-starting accuracy. Right-hand spiral flutes clear chips efficiently during through-hole drilling. Licensed tradespeople and maintenance technicians working in fabrication, mechanical, or construction settings will find this a reliable stock bit for everyday use.

This drill bit is suited for general-purpose drilling tasks in residential and commercial maintenance, light fabrication, and mechanical service environments. The jobber-length body (4.125 inches overall) provides the reach needed for most standard through-hole applications without sacrificing rigidity. The straight-cylindrical shank seats directly in standard keyed or keyless drill chucks. It is appropriate for use in handheld drills, drill presses, and similar equipment where a letter-J diameter hole is required.

Key Features

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard keyed and keyless drill chucks accepting a straight-cylindrical shank in the 0.2500 to 0.3000 inch diameter range.

Installation Notes

Secure the straight shank fully into the drill chuck before operating — ensure the chuck is tightened uniformly. When drilling metal, use appropriate cutting fluid to reduce heat buildup and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed. Follow applicable shop safety practices including eye protection and workpiece clamping.
