Precision Twist Drill 5996427 Taper Length Cobalt Drill Bit

Product Description

The PRECISION TWIST DRILL 5996427 is a taper length cobalt drill bit designed for high-performance drilling in demanding industrial and trade applications. Built from cobalt tool material, it delivers superior heat resistance and edge retention compared to standard high-speed steel bits. The bit features a 135-degree split point for self-centering entry without a center punch, a right-hand spiral flute, and a web-thinned tapered web configuration. At 0.1695 inches in diameter (Wire Size 18) with an overall length of 5.75 inches and a flute length of 3.375 inches, this is a heavy-duty bit sized for precision through-hole work in metal fabrication and mechanical trade settings.

This drill bit is suited for use in metalworking, fabrication, HVAC sheet metal work, plumbing rough-in, and general mechanical trade applications. Its cobalt construction makes it appropriate for drilling alloy steel, stainless steel, cast iron, hardened steel, carbon steel, brass, bronze, copper, aluminum, aluminum alloy, magnesium, nickel, nickel alloy, high-strength bronze, malleable iron, cermet, graphite, reinforced plastic materials, and magnesium alloy. The straight shank accepts standard drill chucks on corded drills, drill presses, and magnetic base drills.

Key Features

• Cobalt tool material for heat resistance and extended tool life in hard and abrasive materials
• 135-degree split point enables self-centering entry, reducing walk on hard surfaces
• Right-hand spiral flute with regular spiral type for efficient chip evacuation
• Web-thinned tapered web reduces thrust and improves drilling performance
• Taper length body provides added rigidity for deeper hole applications versus jobber length
• Straight shank fits standard drill chucks without adapters
• Conforms to ANSI standards

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill bit compatible with standard straight-shank drill chucks. Suitable for use with drill presses, hand drills, and magnetic base drills accepting a 0.1695-inch straight shank. Series M52CO.

Installation Notes

Install in a properly rated drill chuck and tighten securely before operation. Power down and lock out all equipment before bit changes. Use appropriate cutting fluid or coolant when drilling stainless steel, hardened steel, or other abrasive materials to preserve cutting edge life. Ensure workpiece is firmly clamped before drilling to prevent bit deflection or breakage.
