Precision Twist Drill 5995774 Cobalt Drill Bit 0.1520 in

Product Description

The PRECISION TWIST DRILL 5995774 is a taper length cobalt drill bit designed for high-performance drilling in demanding trade and industrial applications. Measuring 0.1520 inches in diameter (Wire Size 24) with a 3-inch flute length and an overall length of 5-3/8 inches, this bit features a 135-degree split point for self-centering entry without a center punch. The cobalt tool material and coated finish provide elevated heat and wear resistance. The tapered web configuration and web-thinned geometry reduce thrust and improve chip evacuation. Right-hand spiral flute direction and a straight shank at 0.1520 inches make it compatible with standard chucks.

This drill bit is suited for residential and commercial maintenance, fabrication shops, and mechanical contracting environments where a wide range of materials must be drilled. The M52CO series is rated for use in 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, cermet, graphite, and reinforced plastic materials. The 6xD flute-to-diameter ratio supports deeper drilling passes with adequate chip clearance.

Installation Notes

This bit is installed by machinists, maintenance mechanics, pipefitters, and general tradespeople using standard drill presses, hand drills, or CNC equipment with a compatible chuck. Secure the straight shank firmly in the chuck before operation and verify chuck runout is within acceptable limits. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable shop safety and tool-use protocols per your trade or facility guidelines.
