Precision Twist Drill 6000621 Jobber Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000621 is a jobber length drill bit designed for general-purpose drilling in a wide range of materials. Manufactured from high speed steel with a bright uncoated finish, this bit features a 118-degree standard point angle and a right-hand spiral flute configuration. The straight-cylindrical shank measures 0.4134 inches in diameter, matching the cutting diameter for secure chuck retention. At 5.2362 inches overall length with a flute length of 3.4252 inches, it provides the reach and chip-clearing capacity needed for everyday production and maintenance drilling tasks. Installation is performed by licensed machinists, maintenance technicians, and trade professionals working across mechanical, HVAC, plumbing, and electrical applications.

This drill bit is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It conforms to DIN 338 and ANSI standards, making it a reliable choice for shops and field technicians who require consistent, specification-grade tooling. The web-thinned, tapered web design reduces thrust requirements at the point, improving entry in tougher materials. It is sold individually and is appropriate for use in hand drills, drill presses, and CNC equipment where a straight-shank bit is required.

Compatibility

Designed as a general-purpose jobber length drill bit suitable for use in standard three-jaw chucks, keyless chucks, and collet systems that accept a 0.4134-inch straight-cylindrical shank. Compatible with hand drills, drill presses, and CNC machining centers. Fits Series 2A tooling requirements per DIN 338 and ANSI standards.

Installation Notes

This bit is installed by machinists, HVAC technicians, plumbers, electricians, and maintenance professionals using standard drill chucks or collet holders. Ensure the shank is fully seated and the chuck is securely tightened before operation. Power down all equipment before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to extend tool life and maintain dimensional accuracy.
