Precision Twist Drill 5996324 Cobalt Drill Bit 5/32 in

Product Description

The PRECISION TWIST DRILL 5996324 is a taper length cobalt drill bit designed for high-performance drilling across a wide range of metals and engineering materials. Built to the M51CO series standard, it features a 135-degree split point for self-centering entry without a center punch and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The 5/32 inch (0.1562 inch) diameter straight shank fits standard drill chucks, and the 3 inch spiral flute length provides a 6xD flute-to-diameter ratio suited for deeper hole applications. Cobalt construction delivers heat resistance and edge retention when drilling hardened or abrasive materials.

This bit is intended for use in industrial, commercial, and trade applications where standard high-speed steel tooling falls short. It is well suited for drilling alloy steel, stainless steel, cast iron, hardened steel, nickel alloys, and high-strength bronze, as well as non-ferrous metals such as aluminum, brass, copper, and magnesium alloys. Machinists, tool-and-die workers, pipefitters, and sheet metal fabricators will find it appropriate for hand drill, drill press, and CNC drilling operations where precision entry and extended tool life are required.

Key Features

• Cobalt tool material for superior heat resistance and edge retention in hard and abrasive materials
• 135-degree split point for self-centering drilling without a center punch
• Web-thinned tapered web reduces drilling thrust and improves chip flow
• 3 inch spiral flute length with 6xD flute-to-diameter ratio for deeper hole capability
• Right-hand cut with regular spiral for compatibility with standard drill chucks and machines
• Straight shank at 0.1563 inch diameter for secure chuck grip; no threaded shank or coolant-through feature
• Meets ANSI standards; heavy-duty grade construction

Compatibility

Designed as a taper length replacement or supplemental drill bit for applications requiring the M51CO series 5/32 inch cobalt drill. Compatible with standard drill chucks accepting a straight shank. Listed material applications include 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.

Installation Notes

This bit is installed and operated by machinists, fabricators, and trade professionals using drill presses, hand drills, or CNC equipment. Secure the straight shank firmly in the chuck before operation and verify chuck capacity accommodates a 0.1563 inch shank diameter. Power down or de-energize the machine completely before changing bits. Do not exceed the recommended cutting speed for the workpiece material, and use appropriate cutting fluid when drilling ferrous or hardened materials to preserve edge life.
