Precision Twist Drill 6000413 Reduced Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000413 is a reduced shank cobalt drill bit designed for demanding drilling applications in metalworking and trade environments. It features a 37/64 inch (0.5781 inch) cutting diameter with a 1/2 inch straight-cylindrical shank, making it compatible with standard 1/2 inch chucks without requiring a larger capacity machine. The 118-degree split point promotes accurate starting and reduces walking on flat surfaces. Built from cobalt steel with a bright uncoated finish, this bit handles ferrous metals and a range of secondary materials. Licensed tradespeople and machinists working in fabrication, mechanical, and HVAC service settings rely on this bit for consistent performance in hard-material drilling.

This drill bit is suited for right-hand drilling operations in residential and commercial trade and light industrial settings. Primary workpiece materials include ferrous metals. Secondary compatible materials include aluminum, copper, magnesium, nickel, titanium, cermet, and synthetic materials. The reduced shank design allows a larger cutting diameter to be used in standard 1/2 inch chuck equipment, making it a practical choice when drilling oversized holes without specialty tooling. The Series R56CO designation identifies this as part of PRECISION TWIST DRILL's cobalt reduced shank line.

Key Features

• Cobalt steel construction for heat resistance and durability in ferrous and hard-metal drilling
• 118-degree split point for accurate positioning and reduced thrust on entry
• Reduced shank design — 37/64 inch cutting diameter on a 1/2 inch shank for use in standard chucks
• Right-hand cut with regular spiral fluting for efficient chip evacuation
• Bright uncoated finish — no coating to flake or delaminate during high-heat drilling
• Meets ANSI standards for dimensional consistency

Compatibility

Designed for use with standard 1/2 inch drill chucks on corded drills, drill presses, and milling machines. Suitable for ferrous metal, aluminum, copper, magnesium, nickel, titanium, cermet, and synthetic workpiece materials per Series R56CO specifications.

Installation Notes

This bit is installed and operated by machinists, pipefitters, HVAC technicians, and other trade professionals using drill presses or hand-held power drills with 1/2 inch chuck capacity. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life, unless the application requires dry cutting. Inspect the cutting edges before each use and replace the bit if the point shows signs of wear or chipping.
