Precision Twist Drill 6000432 Reduced Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000432 is a reduced shank cobalt drill bit designed for drilling into ferrous metals, aluminum, nickel alloys, titanium, copper, magnesium, and synthetic materials. The bit measures 47/64 inch (0.7344 inch) in diameter with a 1/2 inch straight-cylindrical shank, allowing it to chuck into standard 1/2 inch capacity drill chucks despite the larger cutting diameter. Overall length is 6 inches with a 3 inch flute length, supporting a maximum drilling depth of 3 inches. The 118-degree split point promotes accurate starting and reduces walking on entry. Cobalt construction provides heat resistance for demanding drilling applications in hard and abrasive materials.

This drill bit is suited for shop, maintenance, and field applications where drilling into ferrous metals and non-ferrous alloys is required. The reduced shank design makes it compatible with standard 1/2 inch drill chucks and drill presses, extending usable bit range without requiring larger equipment. It is appropriate for use in fabrication, industrial maintenance, HVAC, plumbing, and mechanical contracting environments where hard-material drilling is routine. Right-hand cut and regular spiral flutes provide efficient chip evacuation during through-hole and blind-hole operations.

Key Features

• 47/64 inch cutting diameter (0.7344 inch decimal) with 1/2 inch reduced straight-cylindrical shank
• Cobalt tool material for heat resistance and durability in ferrous and hard alloy materials
• 118-degree split point angle for accurate positioning and reduced thrust on entry
• 3 inch flute length supports up to 3 inches of drilling depth per pass
• Bright/uncoated finish — no coating to chip or peel during regrinding
• Right-hand cut with regular spiral flutes for consistent chip removal
• ANSI standard construction; Series R56CO

Compatibility

Designed for use in any 1/2 inch capacity drill chuck or drill press. Suitable for drilling ferrous metals, aluminum, cermet, copper, magnesium, nickel, synthetic, and titanium workpiece materials per Series R56CO specifications.

Installation Notes

Install in a 1/2 inch drill chuck and tighten securely with a chuck key before operation. Secure the workpiece firmly before drilling to prevent rotation or movement. Use appropriate cutting fluid or coolant when drilling hard ferrous metals to extend bit life, noting this bit does not have an internal coolant channel. Wear appropriate eye and hand protection in accordance with applicable shop safety standards.
