Precision Twist Drill 5995714 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5995714 is a taper length cobalt drill bit from the M52CO series, designed for heavy-duty drilling in a wide range of ferrous and non-ferrous materials. It carries a No. 5 wire gauge size with a decimal diameter of 0.2055 inches and features a 135-degree split point for self-centering starts without a center punch. The gold oxide coating provides additional heat and wear resistance. With a straight cylindrical shank and right-hand spiral flute, this bit is a reliable choice for production and maintenance drilling in demanding shop and field environments.

This taper length bit is well suited for drilling in alloy steel, carbon steel, stainless steel, cast iron, aluminum, brass, bronze, copper, nickel alloys, magnesium, hardened steel, and reinforced plastics. The taper length body provides extra reach compared to a jobber-length bit, making it useful when access depth is a factor. It is commonly used by machinists, maintenance technicians, and fabricators working in industrial, commercial, and field repair settings.

Key Features

• No. 5 wire size with 0.2055 inch decimal diameter for precise hole sizing
• 135-degree split point for self-centering entry and reduced thrust
• Cobalt tool material with gold oxide finish for extended tool life in hard and abrasive materials
• Taper length body with 3.625 inch flute length provides added reach over standard jobber bits
• Web-thinned tapered web configuration reduces cutting resistance and heat buildup
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed for use in standard drill chucks accepting a 0.2055 inch straight cylindrical shank. Suitable for drilling alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, high-strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic, stainless steel, and cermet workpieces.

Installation Notes

Install in a drill press, hand drill, or milling machine chuck rated for the shank diameter before powering on equipment. Secure the workpiece firmly before drilling and use appropriate cutting fluid for the material being drilled to extend bit life and improve finish. Inspect the cutting edges before each use and replace if chipping or dulling is observed. Follow applicable shop safety standards and wear eye protection during all drilling operations.
