Import 22431 Jobber Length Drill Bit 5/32 Inch Hss

Product Description

The IMPORT 22431 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. The bit is manufactured from high speed steel with a gold oxide coating that reduces friction and provides moderate heat resistance during use. It measures 5/32 inch (0.1562 inch decimal) in diameter with an overall length of 3.125 inches and a flute length of 2 inches. The 118-degree split point starts on contact without a center punch, reducing walking on flat surfaces. This bit is a standard item for electricians, plumbers, HVAC technicians, and general trade use wherever a fractional HSS jobber bit is called for.

The 22431 fits standard 3-jaw drill chucks via its straight cylindrical shank. The 5/32 inch shank diameter matches the cutting diameter, so it seats securely in any chuck accepting fractional bits in this size range. Its right-hand spiral flute geometry clears chips efficiently during through-hole and blind-hole drilling. The general-purpose grade makes it appropriate for light to moderate production use, maintenance tasks, and field service work across residential and light commercial applications.

Key Features

• 118-degree split point for self-starting entry without a center punch
• Gold oxide coating reduces friction and extends service life in general-purpose drilling
• High speed steel construction handles heat generated in metal drilling
• Web-thinned tapered web reduces thrust force needed during drilling
• Regular spiral flute with right-hand cut for standard chuck use
• Straight cylindrical shank fits all standard 3-jaw drill chucks

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill press, handheld drill, or right-angle drill equipped with a chuck accepting 5/32 inch straight-shank bits.

Installation Notes

Secure the shank fully in the chuck jaws before drilling and verify the chuck key is removed before powering the tool. Use appropriate cutting fluid or lubricant when drilling ferrous metals to reduce heat buildup and prolong bit life. Reduce feed pressure as the bit breaks through the exit side of the workpiece to prevent grabbing and bit breakage. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
