Import 22447 Jobber Length Drill Bit 13/32 in Hss

Product Description

The IMPORT 22447 is a jobber-length twist drill bit designed for general-purpose metal drilling in trade and industrial applications. It measures 13/32 inches (0.4062 inches decimal) in diameter with a 5-1/4 inch overall length and a 3-7/8 inch flute length. The bit is manufactured from high speed steel with a gold oxide finish that provides mild lubricity and corrosion resistance during use. A 118-degree split point reduces walking on entry and lowers the thrust needed to start the hole. The straight cylindrical shank measures 3/8 inch in diameter, fitting standard three-jaw drill chucks found on corded drills, drill presses, and magnetic base drills.

This bit is suited for drilling mild steel, aluminum, copper, brass, cast iron, and similar materials encountered in HVAC, plumbing, and electrical rough-in work. The regular spiral flute clears chips efficiently in through-hole applications. Web thinning on the tapered web reduces cutting resistance and heat buildup at the tip, making it practical for hand-held drilling on structural steel, angle iron, electrical enclosures, conduit hangers, and sheet metal assemblies where a fractional jobber-length bit is required.

Key Features

• 118-degree split point for reduced walking and lower entry thrust
• High speed steel construction for durability across ferrous and non-ferrous materials
• Gold oxide finish provides mild lubricity and corrosion resistance
• Web-thinned tapered web reduces cutting resistance and tip heat
• Regular spiral flute promotes efficient chip evacuation in through-hole drilling
• 3/8 inch straight cylindrical shank fits standard three-jaw chuck configurations

Compatibility

Designed as a general-purpose jobber-length drill bit in the 0.4000 to 0.5000 inch decimal size range, compatible with any standard three-jaw drill chuck that accepts a 3/8 inch straight cylindrical shank, including portable drills, drill presses, and magnetic base drills.

Installation Notes

Secure the shank fully in the chuck and verify it is centered before drilling. Power down the drill and disconnect from the power source before changing bits. Use cutting fluid or oil when drilling hardened steel or thick-section metal to extend bit life and manage heat. Wear eye protection in compliance with applicable jobsite safety requirements.
