Value Collection KP65119 Drill Bit Letter R 0.3390 in Hss

Product Description

The VALUE COLLECTION KP65119 is a jobber length drill bit sized to Letter R (0.3390 inches) and manufactured from high speed steel with an oxide coating for improved wear resistance. The bit features a 118-degree standard point angle and a spiral flute with a right-hand cutting direction, making it suitable for general-purpose drilling in metal, wood, and plastic. Overall length is 4.75 inches with a flute length of 3.4375 inches. The straight-cylindrical shank seats securely in standard drill chucks. This bit is intended for use by machinists, maintenance technicians, pipefitters, and other trade professionals requiring consistent, accurate hole sizing.

This drill bit is designed for general-purpose jobber length applications across a wide range of materials. The Letter R diameter (0.3390 inches) is a common size for tapping, reaming prep, and clearance holes in structural and fabrication work. The web-thinned, tapered web configuration reduces thrust and improves chip evacuation during drilling. Suitable for use in hand-held drills, drill presses, and CNC setups where a straight-cylindrical shank is appropriate.

Installation Notes

Secure the shank fully in the chuck before operation and verify chuck key is removed prior to powering on the drill. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and improve hole quality. Allow the bit to cool between extended drilling operations to prevent heat-induced softening of the high speed steel. Follow applicable OSHA and shop safety standards for rotating tool use.
