Precision Twist Drill 6000264 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000264 is a taper length high speed steel drill bit designed for precision drilling in a wide range of materials. It measures 0.0260 inches in diameter, corresponding to wire gauge size 71, with an overall length of 2 inches and a 118-degree standard point angle. The bright, uncoated finish is standard for general-purpose HSS tooling. The spiral flute geometry and web-thinned, tapered web configuration improve chip evacuation and reduce walking at entry. This bit is suited for machinists, tool and die workers, and maintenance technicians working with small-diameter, close-tolerance hole requirements.

The 6000264 is a general-purpose taper length bit from the Series R52 line. The 0.75-inch flute length with a 6xD ratio supports controlled chip removal in deeper passes relative to diameter. The straight, non-threaded shank seats directly in standard drill chucks. It is appropriate for use in bench drill presses, drill-press mills, and hand-held electric drills wherever a wire-size bit in the 71 range is called out. Typical applications include light fabrication, instrument manufacturing, and maintenance drilling in metal and non-metallic materials.

Key Features

• Wire size 71 designation, 0.0260-inch diameter for close-tolerance small-hole work
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry
• High speed steel construction for general-purpose performance across metals and non-metals
• Right-hand spiral flute promotes efficient chip evacuation in taper-length drilling
• Bright, uncoated finish; compatible with cutting fluids and coolants applied externally
• Straight shank fits standard drill chucks without adapters; non-threaded for quick changes

Compatibility

Designed for use in standard drill chucks accepting straight-shank bits at 0.0260-inch diameter. Rated for drilling in 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. Conforms to ANSI standards for taper length drill geometry.

Installation Notes

Install the shank fully into the drill chuck and tighten securely before operation. At this diameter, bit deflection and breakage risk increase significantly if the workpiece or bit is not adequately supported; use a drill press or guided fixture when possible. Apply a suitable cutting fluid for steel or cast iron applications to extend tool life and improve hole finish. Inspect the cutting edges before each use, as small-diameter HSS bits are susceptible to tip damage from improper storage or handling.
