Precision Twist Drill 6000225 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000225 is a taper length, high speed steel drill bit designed for general-purpose drilling across a wide range of materials. It measures 35/64 inch (0.5469 inches) in diameter with an overall length of 8.25 inches and a flute length of 4.875 inches. The 118-degree standard point angle and web-thinned, tapered web geometry reduce entry force and improve chip clearing. The bright, uncoated finish suits applications where coating is unnecessary or where cost efficiency is the priority. Right-hand spiral fluting and a straight shank make this bit compatible with standard drill chucks. Licensed machinists, pipefitters, plumbers, and HVAC technicians reach for this style of bit when a longer reach than a jobber bit is required without stepping up to an extra-length configuration.

This Series R51 taper length bit is suited for drilling through alloy steel, carbon steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, magnesium, magnesium alloy, nickel, nickel alloy, cermet, graphite, and reinforced plastic materials. The longer flute-to-diameter ratio of 6xD gives it added reach for deeper hole applications common in mechanical, plumbing, and HVAC rough-in work. It is manufactured to ANSI standards, making it a reliable choice for shop and field use where dimensional consistency matters.

Key Features

• 35/64 inch (0.5469 inches) diameter with 8.25-inch overall length for extended reach
• High speed steel construction handles both ferrous and non-ferrous materials
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and clean entry
• Right-hand spiral flute with 6xD flute-to-diameter ratio for efficient chip evacuation in deeper holes
• Bright, uncoated finish — no coating buildup concerns for general-purpose use
• Straight shank fits standard drill chucks without adapters
• Manufactured to ANSI standards for consistent dimensional performance

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill chucks accepting a 0.5469-inch straight shank. Suitable for use in drill presses, hand drills, and magnetic base drills across shop and field applications.

Installation Notes

Installation and use should follow standard machine tool safety practices. Secure the workpiece before drilling and confirm the drill chuck is fully tightened before operation. For deep-hole drilling, periodically retract the bit to clear chips and prevent heat buildup, especially when working in steel or stainless steel. Disconnect or de-energize the drill press or power tool before changing or securing bits.
