Precision Twist Drill 5996416 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5996416 is a taper length cobalt drill bit in the M52CO series, sized at wire gauge 14 (0.1820 inches decimal). It features a 135-degree split point with web thinning for self-centering starts and reduced thrust in hard materials. The spiral flute geometry and tapered web configuration promote chip evacuation and rigidity through the cut. With a gold oxide coating applied over the cobalt substrate, the bit is built for heavy-duty drilling in production and maintenance environments. Machinists, tool-and-die technicians, and industrial maintenance mechanics are the primary users.

This taper length drill bit is suited for drilling into a wide range of materials including alloy steel, carbon steel, stainless steel, hardened steel, cast iron, malleable iron, brass, bronze, high-strength bronze, copper, aluminum, aluminum alloy, magnesium, magnesium alloy, nickel, nickel alloy, cermet, graphite, and reinforced plastic. The longer flute length compared to a jobber-length bit allows deeper hole penetration without a drill extension. It is well matched to drill press, CNC drilling, and manual machine setups where a straight-cylindrical shank is required.

Key Features

• Wire size 14 (0.1820 inches) with matching straight-cylindrical shank diameter
• 135-degree split point with web thinning for self-centering and reduced entry thrust
• Cobalt tool material with gold oxide coating for heat and wear resistance in hard metals
• 3-3/8 inch flute length at a 6xD flute-to-diameter ratio for deeper reach
• Right-hand spiral flute with tapered web for efficient chip clearing
• ANSI standard compliant, heavy-duty grade construction

Compatibility

Designed as an OEM-style taper length replacement drill bit compatible with standard straight-shank drill chucks and collet holders accepting a 0.1820-inch shank diameter.

Installation Notes

Install in a drill press, lathe tailstock, or CNC spindle equipped with a chuck or collet rated for straight-cylindrical shanks. Ensure the shank is fully seated and the chuck is tightened before operation. Use cutting fluid appropriate to the workpiece material to prolong tool life, particularly when drilling stainless or hardened steel. Follow applicable shop safety practices and machine-guarding requirements during setup and use.
