Precision Twist Drill 5995697 Cobalt Drill Bit No. 32

Product Description

The PRECISION TWIST DRILL 5995697 is a taper length cobalt drill bit in the M52CO series, sized at No. 32 (0.116 inches diameter) with a 135-degree split point and gold oxide finish. Built from cobalt tool steel for elevated heat and wear resistance, this bit handles demanding materials where standard high-speed steel falls short. The web-thinned, tapered web construction reduces thrust and improves self-centering at entry. With a 2.75-inch flute length and 5.125-inch overall length, it provides extra reach for deep-hole applications. Right-hand spiral flutes evacuate chips efficiently. Licensed machinists, tool-and-die techs, pipefitters, and maintenance mechanics rely on this bit for precision drilling in production and field environments.

The M52CO taper length series is suited for drilling into alloy steel, carbon steel, stainless steel, cast iron, malleable iron, hardened steel, brass, bronze, copper, aluminum, aluminum alloy, magnesium, magnesium alloy, nickel, nickel alloy, high-strength bronze, cermet, graphite, and reinforced plastic. The extended flute-to-diameter ratio of 6xD makes it appropriate for through-hole work in thicker stock where a jobber-length bit cannot reach. It performs in both manual and machine spindle applications across manufacturing, maintenance, and industrial service settings.

Key Features

• Cobalt tool steel construction for high-heat and abrasion resistance in tough materials
• 135-degree split point for self-centering entry and reduced walking on curved or flat surfaces
• Web-thinned, tapered web reduces drilling thrust and extends bit life
• Gold oxide finish improves lubricity and chip flow
• 6xD flute-to-diameter ratio provides extended reach for deep-hole drilling
• Right-hand spiral flute with regular helix for reliable chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style replacement and production-use taper length drill bit compatible with any standard drill chuck or spindle accepting a straight cylindrical shank at 0.116 inches diameter. Conforms to ANSI standards for taper length drill bits.

Installation Notes

This bit is installed by a machinist or qualified technician into a drill press, CNC machining center, or hand-held drill motor with a compatible chuck. Secure the shank firmly in the chuck before operation and confirm spindle speed is appropriate for the workpiece material and bit diameter. Use cutting fluid or coolant where required by the material being drilled; note that this bit does not have internal coolant-through capability. Inspect the cutting edges and web thinning for wear or chipping before each use and replace if geometry is compromised.
