Precision Twist Drill 6000840 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000840 is a taper length high speed steel drill bit designed for general-purpose drilling across a wide range of metallic and non-metallic materials. It measures 0.8268 inches in diameter with a 118-degree standard point angle and a spiral flute configuration. The bit features a straight shank with a web-thinned, tapered web design that reduces cutting resistance and improves chip evacuation. Overall length is 10-9/32 inches, and flute length is 6-23/32 inches, giving this bit the extended reach needed for through-hole work in thicker stock. This tool is intended for use by machinists, maintenance technicians, and trade professionals working on fabrication or field drilling applications.

The 6000840 is suited for drilling in alloy steel, carbon steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, nickel, nickel alloy, magnesium, magnesium alloy, cermet, graphite, and reinforced plastic materials. Its general-purpose grade and regular spiral type make it a practical choice for production shops and job-site work where a single bit must handle diverse material types. The bright uncoated finish is standard for HSS tooling used across varied materials without the need for a specialized coating.

Material compatibility includes alloy steel, aluminum, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, magnesium, nickel alloys, stainless steel, and reinforced plastic materials.

Installation Notes

This bit is installed by machinists and maintenance technicians using standard chuck or collet systems rated for the 0.8268-inch straight shank diameter. Ensure the drilling machine is fully powered down and secured before changing tooling. Use appropriate cutting fluid or lubricant for the material being drilled to extend bit life and maintain hole quality. Always verify chuck grip and runout before beginning a drilling operation.
