Precision Twist Drill 6000272 9/16 Inch Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000272 is a taper length, high speed steel (HSS) drill bit designed for general-purpose drilling across a wide range of metallic and non-metallic materials. It measures 9/16 inch (0.5625 inches) in diameter with a 118-degree standard point angle and a bright, uncoated finish. The spiral flute geometry runs 4-7/8 inches in length, yielding a 6xD flute-to-diameter ratio that supports chip evacuation in deeper holes. Web thinning reduces cutting resistance at the point, making starts more controlled. The straight shank seats directly into standard drill chucks without adapters. At 8-1/4 inches overall length, this bit is suited for applications requiring reach beyond what a jobber-length bit provides. Weight is 0.5 pounds.

This bit is built for trade professionals drilling in fabrication shops, mechanical rooms, HVAC installations, plumbing rough-ins, and general industrial settings. The R51 series targets general-purpose metalworking where a longer reach is needed without stepping up to an extra-length bit. Compatible materials include alloy steel, carbon steel, stainless steel, cast iron, malleable iron, hardened steel, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, nickel, nickel alloy, magnesium, magnesium alloy, cermet, graphite, and reinforced plastic materials. Right-hand cut only.

Key Features

• 9/16 inch diameter with 118-degree standard point for clean entry in a broad range of materials
• High speed steel construction provides heat and wear resistance during extended drilling cycles
• Taper length body (8-1/4 inches overall) offers added reach compared to standard jobber bits
• Web-thinned, tapered web configuration reduces thrust and improves centering
• Bright/uncoated finish suits general-purpose use where coating is not required
• Meets ANSI standards for dimensional accuracy and performance

Compatibility

Designed as a general-purpose taper length drill bit for use in any standard drill chuck or drill press that accepts a 9/16 inch straight shank. Suitable for hand-held power drills, drill presses, and magnetic base drills configured for straight shank tooling.

Installation Notes

Installation and use should be performed by a qualified machinist, maintenance technician, or trade professional familiar with rotary cutting tools. Secure the shank fully in the chuck and verify runout before drilling. Always wear appropriate eye and hand protection, and ensure the workpiece is properly clamped before beginning a cut. Do not exceed the rated speed for the material being drilled, and allow adequate chip clearance by withdrawing the bit periodically during deep-hole operations.
