Precision Twist Drill 6001370 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6001370 is a taper length drill bit designed for general-purpose drilling across a wide range of metals and materials. Built from high speed steel with a bright/uncoated finish, it features a 0.1575 inch diameter, a 118-degree standard point angle, and a right-hand spiral flute configuration. The tapered web and web-thinned point reduce thrust at entry and help maintain accurate hole starts. At 4.6875 inches overall length with a 3.0625 inch flute length, this bit provides extended reach compared to jobber-length equivalents. It is sized and configured for use by machinists, maintenance technicians, and fabricators working with drill presses, CNC machines, or hand-held power tools.

The 6001370 is suited for drilling into alloy steel, carbon steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, nickel, nickel alloy, magnesium, magnesium alloy, cermet, graphite, and reinforced plastic materials. Its taper length body makes it appropriate for applications requiring deeper hole depths than a standard jobber bit allows, including through-hole drilling in thick plate or structural members. The straight shank fits standard drill chucks without adapters.

Installation Notes

Install in a drill press, milling machine spindle, or hand-held drill with a chuck rated for the shank diameter. Ensure the workpiece is securely clamped before drilling to prevent movement and bit deflection. Power down and de-energize any machine tool before changing or seating the bit. Use appropriate cutting fluid for ferrous materials to extend tool life and improve hole finish.
