Precision Twist Drill 6001444 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6001444 is a taper length drill bit engineered for general-purpose drilling across a wide range of materials. Built from high speed steel with a bright, uncoated finish, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip clearance. The straight shank measures 0.2835 inches in diameter, and the overall length is 6.125 inches, making this bit well-suited for applications requiring extended reach beyond what a jobber-length bit provides. It is installed by machinists, maintenance technicians, and trade professionals working with drill presses, lathes, and hand-held drilling equipment.

The 6001444 is a Series 5ATL taper length bit rated for general-purpose use in production and maintenance drilling environments. The 4.031-inch spiral flute length provides increased depth capacity while maintaining chip evacuation. This bit is dimensionally conforming to DIN 340 standards, making it a recognized specification in both domestic and international shop settings. Right-hand cut geometry is standard, compatible with conventional drill press and machine tool spindle rotation.

Compatibility

Rated 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. The straight 0.2835-inch shank fits standard drill chucks accepting that shank diameter.

Installation Notes

This bit is installed by machinists and maintenance technicians using drill presses, milling machines, or hand-held electric drills equipped with a compatible chuck. Secure the shank fully in the chuck before operation and verify chuck key removal before powering the machine. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Inspect the cutting edges for wear or damage before each use and replace the bit if chipping or dulling is observed.
