Precision Twist Drill 6000164 Taper Length Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 6000164 is a taper length high speed steel drill bit designed for general-purpose drilling across a wide range of materials. It measures 0.0860 inches in diameter with a 118-degree standard point angle and features a bright/uncoated finish. The spiral flute geometry with a 6xD flute-to-diameter ratio promotes efficient chip evacuation. The straight shank allows for straightforward chuck mounting. This bit is suited for use by machinists, maintenance technicians, and fabricators working in shop or field environments.

This Series R52 drill bit is applicable across residential, commercial, and industrial settings where taper length reach is required. The 2.25-inch flute length and 4.25-inch overall length provide additional reach compared to jobber-length bits, making it useful in deeper-hole applications. The right-hand spiral flute cut and web-thinned, tapered web configuration improve penetration and reduce thrust in both manual and machine drilling setups.

Installation Notes

This drill bit is installed into a standard drill chuck sized for a 0.0860-inch straight shank. Secure the shank fully in the chuck before operation and confirm proper alignment to avoid bit wander at entry. Use appropriate cutting fluid or lubricant when drilling ferrous metals or stainless steel to extend tool life and maintain hole quality. Follow applicable shop safety practices and machine guarding requirements during use.
