Precision Twist Drill 6000304 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000304 is a taper length twist drill bit designed for general-purpose drilling across a wide range of materials. It measures 0.2950 inches in diameter (Letter Size M) with a 4-inch flute length and an overall length of 6-3/8 inches. The bit is manufactured from high speed steel with a bright, uncoated finish. It features a 118-degree standard point angle, a right-hand spiral flute, a straight shank, and a web-thinned tapered web configuration. This drill bit is sold individually and suited for use by machinists, maintenance technicians, fabricators, and trade professionals who need reliable general-purpose performance in metal and non-metal materials.

This drill bit is appropriate for drilling in residential, commercial, and industrial settings where a taper length bit provides extra reach beyond a jobber-length tool. The 6xD flute-to-diameter ratio gives added clearance in deeper holes. It conforms to ANSI standards and carries a Series R55 designation from PRECISION TWIST DRILL. Compatible material applications include 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.

Installation Notes

Install the straight shank securely in a compatible drill chuck rated for the intended speed and feed for the workpiece material.
