Precision Twist Drill 6000457 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000457 is a taper length, straight-shank drill bit designed for general-purpose drilling across a wide range of materials. Manufactured from high speed steel with a bright/uncoated finish, it features a 118-degree standard point angle and a right-hand spiral flute for efficient chip evacuation. The bit measures 0.2720 inches in diameter (Letter size I) with an overall length of 6.25 inches and a flute length of 3.875 inches. The tapered web configuration and web-thinned point reduce entry resistance and improve centering accuracy. Licensed HVAC technicians, machinists, and general tradespeople reach for this bit when drilling through ferrous and non-ferrous metals in both shop and field conditions.

This drill bit fits standard drilling applications in residential and commercial maintenance, fabrication, and repair environments. Its 6xD flute-length-to-diameter ratio makes it well suited for holes requiring greater depth than a jobber-length bit provides, without moving to a full extra-length design. The straight shank seats directly into standard drill chucks without adapters. It is part of the PRECISION TWIST DRILL Series R55 line built to ANSI standards.

Installation Notes

This bit is installed and removed by a licensed machinist, maintenance technician, or qualified tradesperson using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and verify chuck tightness to prevent slippage. Always power down and de-energize the drill or press before changing bits. Follow applicable shop safety practices and use appropriate cutting fluid for hard or abrasive materials to extend tool life.
