Precision Twist Drill 6000001 Reduced Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000001 is a reduced shank twist drill bit designed for general-purpose drilling in ferrous metals, aluminum, copper, and a range of other materials. The bit measures 43/64 inch (0.6719 inch decimal) in cutting diameter with a 1/2 inch straight-cylindrical shank, allowing it to run in standard 1/2 inch chucks even at larger cutting diameters. Overall length is 6 inches with a 3 inch flute length. The 118-degree standard point angle suits most production and maintenance drilling applications in shops, fabrication facilities, and field service environments. Manufactured from high speed steel with a bright, uncoated finish.

This bit is suited for drilling ferrous metals including mild steel and cast iron, as well as non-ferrous materials such as aluminum, copper, magnesium, nickel, and titanium alloys, plus synthetic materials. The reduced shank design makes it practical when the required hole diameter exceeds the capacity of smaller chucks on standard drill presses, hand drills, and magnetic base drills. It carries a right-hand cut and spiral flute configuration appropriate for general-purpose material removal. Machinists, maintenance technicians, pipefitters, and electricians routinely use bits in this size range for structural and equipment work.

Key Features

• 43/64 inch cutting diameter (0.6719 inch decimal) with 1/2 inch reduced shank for compatibility with standard 1/2 inch chucks
• 118-degree standard point angle for general-purpose drilling across a broad range of materials
• High speed steel construction for durability in metal cutting applications
• Bright, uncoated finish — no coating buildup to affect dimensional tolerances
• 3 inch flute length supports drilling up to 3 inches maximum depth
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Series R56 — conforms to ANSI standards

Compatibility

Designed as a general-purpose reduced shank drill bit suitable for use in any 1/2 inch keyed or keyless drill chuck on drill presses, hand drills, and magnetic base drills. Compatible primary workpiece material is ferrous metal; secondary workpiece materials include aluminum, cermet, copper, magnesium, nickel, synthetic, and titanium per Series R56 specifications.

Installation Notes

Secure the 1/2 inch shank fully in the chuck before operation and verify the chuck is tightened to prevent slippage under load. Power down and de-energize the drill press or disconnect the hand drill before changing bits. No coolant is required per the product specification, but appropriate cutting fluid may be used at the operator's discretion for extended production runs. Follow applicable shop safety practices and applicable ANSI standards for drilling operations.
