Precision Twist Drill 5995704 Cobalt Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5995704 is a taper length cobalt drill bit in the M52CO series, sized to wire gauge No. 36 (0.1065 inches decimal equivalent). Built for high-performance drilling, it features a 135-degree split point that is self-centering and reduces walking on entry. The spiral flute geometry is web-thinned with a tapered web configuration, which lowers thrust and improves chip evacuation. A gold oxide finish provides additional lubricity and heat resistance. This bit is designed for machinists, tool-and-die techs, and maintenance professionals who need a heavy-duty solution for tight-tolerance through-hole work in demanding materials.

The 5995704 is suited for drilling in a wide range of materials including alloy steel, carbon steel, stainless steel, hardened steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high-strength bronze, copper, nickel, nickel alloy, magnesium, magnesium alloy, reinforced plastic, cermet, graphite, and tellurium-containing alloys. It is appropriate for use in machine shops, maintenance and repair operations, and production environments where a longer flute length is required to reach depth or clear chips in deeper holes. The straight cylindrical shank fits standard drill chucks without adapters.

Key Features

• Wire size No. 36 — 0.1065 inches decimal diameter — for precise small-bore work
• 135-degree split point is self-centering and reduces drill walking without a center punch
• Cobalt tool material with gold oxide finish for heat and wear resistance in tough materials
• 2.5-inch flute length provides extended reach and chip clearance in deeper holes
• Web-thinned, tapered web configuration reduces cutting thrust and improves penetration rate
• Right-hand spiral flute, straight cylindrical shank — fits standard drill chucks directly

Compatibility

Designed as a heavy-duty taper length replacement drill bit conforming to ANSI standards, compatible with any standard drill chuck accepting a 0.1065-inch straight cylindrical shank.

Installation Notes

This bit should be installed in a drill press, milling machine, or hand drill with a chuck rated for the shank diameter. Secure the shank fully in the chuck and verify runout before beginning the cut. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, particularly when drilling stainless steel, hardened steel, or nickel alloys. Wear appropriate PPE including eye protection when operating.
