Precision Twist Drill 5995699 Taper Length Drill Bit No 33

Product Description

The PRECISION TWIST DRILL 5995699 is a taper length cobalt drill bit designed for demanding metal-cutting applications in industrial and trade environments. Built to Series M52CO standards, it carries a 135-degree split point with web thinning for self-centering entry and reduced thrust at the start of a cut. The straight cylindrical shank measures 0.1130 inches in diameter, matching the No. 33 wire gauge designation. A gold oxide coating provides lubricity and heat resistance during high-speed drilling. This bit is suited for machinists, tool-and-die workers, pipefitters, and HVAC fabrication shops working with hard or abrasive stock.

The 5995699 is built for high-performance drilling in ferrous and non-ferrous metals, reinforced plastics, and other tough materials. Its taper length geometry gives more reach than a jobber bit without sacrificing rigidity, making it useful in confined bores or deep-hole applications where a standard-length bit falls short. The spiral flute with a right-hand cut clears chips efficiently in continuous cuts. This bit sees regular use in production shops, maintenance facilities, and field fabrication contexts where a wide range of materials must be drilled accurately.

• Cobalt tool material with gold oxide finish for heat and wear resistance
• Taper length body: 2.75-inch flute length, 5.125-inch overall length
• Straight cylindrical shank fits standard drill chucks without adapters
• Regular spiral, right-hand cut with tapered web configuration for reliable chip evacuation

Compatibility

Rated for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, high-strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic, stainless steel, and steel. Designed for use in standard drill chucks accepting a 0.1130-inch straight cylindrical shank.

Installation Notes

Install into a keyed or keyless drill chuck rated for the shank diameter and the intended spindle speed. Secure the workpiece firmly before drilling to prevent walking. When drilling hardened steel or stainless steel, use a cutting fluid to extend bit life and manage heat. Follow applicable shop safety standards and wear appropriate eye protection during all drilling operations.
