Precision Twist Drill 6000451 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000451 is a taper length drill bit designed for general-purpose drilling across a wide range of materials in industrial and trade applications. Built from high speed steel (HSS) with a bright, uncoated finish, this bit measures 0.2610 inches in diameter — equivalent to letter size G — and features a 118-degree standard point angle with web thinning for improved center penetration. The spiral flute design and tapered web configuration promote efficient chip evacuation during drilling. It is suited for use by machinists, millwrights, maintenance technicians, and fabricators working with metal, plastic, and non-ferrous materials.

This drill bit is appropriate for production and maintenance drilling in shop, field, and facility settings. The 6 times diameter flute length ratio gives it greater reach than a jobber-length bit, making it well-suited for deeper hole applications where a standard-length bit falls short. It is compatible with a broad range of workpiece materials including alloy steel, carbon steel, stainless steel, cast iron, aluminum, aluminum alloy, brass, bronze, copper, magnesium, nickel, reinforced plastics, and hardened steel. Straight shank fitment works with standard drill chucks across benchtop drill presses, magnetic drills, and handheld power tools.

Key Features

• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry
• Spiral flute design promotes chip clearing in deep-hole applications
• Bright uncoated finish — no coating to chip or peel, suitable for general-purpose use
• Straight shank accepts standard drill chucks; right-hand cut, non-threaded shank
• Meets ANSI standards; Series R55 general-purpose drill bit grade

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill chucks in drill presses, magnetic base drills, and handheld power tools. Suitable for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, and fabricators using standard drill chucks — no special toolholder is required for the straight shank. Always secure the workpiece before drilling and confirm the chuck is fully tightened before operation. Use appropriate cutting fluid or coolant when drilling harder ferrous materials to extend tool life, noting this bit does not have through-coolant capability. Inspect the cutting edges before use and replace the bit if chipping or excessive wear is present.
