Precision Twist Drill 6000145 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000145 is a taper length high speed steel drill bit designed for general-purpose drilling in a wide range of metallic and non-metallic materials. It features a 0.2090 inch diameter straight shank, a 118-degree standard point angle, and a 6 inch overall length with a 3-5/8 inch spiral flute. The right-hand cut and web-thinned tapered web construction promote clean entry and efficient chip evacuation. This bit is suited for machinists, maintenance technicians, metalworkers, and fabricators who need consistent performance across production and service applications.

The 6000145 is intended for use in drill presses, CNC drilling centers, and hand-held power drills where a taper length bit provides additional reach beyond a jobber length configuration. Its general-purpose grade and bright uncoated finish make it a practical choice for shops working with alloy steel, carbon steel, stainless steel, aluminum, brass, bronze, cast iron, copper, nickel alloys, magnesium, and reinforced plastic materials. It conforms to ANSI standards and belongs to the Series R52 product line.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard drill chucks that accept straight shank bits. Secure the shank fully in the chuck before operation and verify runout before beginning a cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Follow shop safety protocols and applicable ANSI machine guarding standards when operating drilling equipment.
