Precision Twist Drill 6000273 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000273 is a taper length drill bit designed for general-purpose drilling across a wide range of materials. Built from high speed steel with a bright/uncoated finish, this bit features a standard 118-degree split point and a right-hand spiral flute. The straight shank measures 0.1160 inches in diameter, and the overall length is 5.125 inches with a flute length of 2.75 inches. The web-thinned, tapered web configuration reduces thrust and improves chip evacuation. This bit is intended for use by machinists, maintenance technicians, pipefitters, and other trade professionals working with drill presses, lathes, or hand-held equipment.

The 6000273 Series R52 taper length drill bit is suited for production and maintenance drilling in metals, alloys, and select non-metallic materials. Its longer flute length relative to standard jobber bits makes it appropriate for applications requiring deeper hole penetration without a drill extension. It is commonly used in HVAC fabrication, plumbing rough-in, and general mechanical work where a jobber-length bit falls short.

Key Features

• High speed steel construction rated for general-purpose use in ferrous and non-ferrous materials
• 118-degree standard point angle with web thinning to reduce entry thrust
• Spiral flute, right-hand cut with a 6xD flute-to-diameter ratio for deeper reach
• Bright/uncoated finish compatible with cutting fluids and dry drilling
• Straight shank at 0.1160 inches diameter fits standard drill chucks without an adapter
• ANSI-standard geometry for consistent, repeatable hole quality

Compatibility

Designed for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, cermet, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel. Series R52 follows ANSI standards for taper length drill bits.

Installation Notes

Install in a properly sized drill chuck rated for straight-shank bits; confirm chuck jaws are clean and fully tightened before operation. Secure the workpiece firmly to prevent rotation or movement during drilling. Apply appropriate cutting fluid for ferrous materials to extend tool life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
