Walter-titex 5060462 Cobalt Jobber Drill Bit Wire 21

Product Description

The WALTER-TITEX 5060462 is a cobalt jobber length drill bit sized to wire gauge 21, equal to 0.1590 inches in diameter. It features a 130-degree split point and a parabolic flute geometry that improves chip evacuation and reduces heat buildup during drilling. The oxide coating adds surface hardness and lubricity, extending tool life in demanding applications. With a right-hand cut and web-thinned, tapered web construction, this bit is built for high-performance use in production and maintenance environments. Licensed HVAC, mechanical, and industrial technicians will find it suited for tight-tolerance drilling where consistent hole quality is required.

This drill bit is designed for use in blind hole drilling and stack drilling operations. Its primary workpiece materials include cast iron, non-ferrous metals, stainless steel, carbon and alloy steel, and superalloys including titanium. The parabolic flute geometry with an 8xD flute-to-diameter ratio supports deeper chip removal without clogging. The straight-cylindrical shank fits standard drill chucks. It is part of the Series A1247 product line, built to ANSI, ISO, BS, and DIN standards, making it appropriate for both domestic and international application requirements.

Compatibility

Designed for use in standard drill chucks accepting a 0.1590-inch straight-cylindrical shank. Rated for cast iron, non-ferrous metal, stainless steel, steel, and superalloys including titanium. Suitable for blind hole and stack drilling applications.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press, hand drill, or CNC spindle operation. Power down and secure the machine before loading or removing the bit from the chuck. Use appropriate cutting fluid or coolant at the workpiece surface when drilling stainless steel, superalloys, or titanium to manage heat, noting this bit does not have through-coolant capability. Inspect the cutting edge and point before each use and replace if chipping or dulling is observed.
