Import 22448 Jobber Length Drill Bit 27/64 Inch Hss

Product Description

The IMPORT 22448 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. It measures 27/64 inch (0.4219 inch decimal) in diameter with a 118-degree split point and a 5-3/8 inch overall length. The bit is manufactured from high speed steel with an oxide/gold coating that helps reduce friction and extend service life. A straight-cylindrical shank at 3/8 inch diameter seats securely in standard drill chucks. The right-hand spiral flute and web-thinned, tapered web construction improve chip evacuation and reduce walking at the start of a cut.

This bit is suited for use in hand drills, drill presses, and CNC drilling applications where a standard jobber-length reach is appropriate. The 118-degree split point allows self-centering on flat or curved surfaces without a center punch in many applications. General-purpose grade construction makes it a practical choice for maintenance, fabrication, and service work across HVAC, plumbing, electrical, and mechanical trades. The 3-15/16 inch flute length provides adequate chip clearance for through-hole drilling in typical stock thicknesses.

Key Features

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw drill chuck accepting a 3/8 inch straight shank, including hand drills, drill presses, and CNC spindles.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify the chuck key is removed before starting the drill. Use appropriate cutting fluid or lubricant when drilling ferrous metals to preserve edge life. Always wear eye protection and secure the workpiece to prevent rotation. Dispose of worn or chipped bits promptly, as a damaged cutting edge increases heat and reduces hole accuracy.
