Precision Twist Drill 6000045 Reduced Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000045 is a reduced shank twist drill bit machined from high-speed steel and designed for general-purpose drilling in metal fabrication and maintenance applications. The bit measures 9/16 inch in diameter with a 1/2 inch Weldon flat shank, allowing it to seat securely in standard 1/2 inch chucks and holders without slipping under torque. The 118-degree standard point angle suits a wide range of ferrous and non-ferrous materials. With a 6 inch overall length and a bright, uncoated finish, this bit is built for straightforward performance where no specialized coating is required.

This drill bit is suited for use in machine shops, fabrication facilities, HVAC mechanical rooms, plumbing rough-in work, and electrical trade applications where drilling through ferrous metals, aluminum, copper, and similar materials is routine. The Series R57 reduced shank design allows a larger-diameter bit to be run in a standard 1/2 inch drill chuck, making it a practical choice when a full-shank bit of the same diameter would not fit available equipment. It is appropriate for both manual drill press work and light CNC or mill setups.

Key Features

• 9/16 inch cutting diameter with 1/2 inch reduced Weldon flat shank for use in standard 1/2 inch chucks
• 118-degree standard point angle for general-purpose drilling in ferrous and non-ferrous metals
• 3 inch flute length with regular spiral flute geometry for efficient chip evacuation
• High-speed steel construction provides durability across a broad range of workpiece materials
• Bright, uncoated finish — no coating degradation concern in moderate-heat or coolant-free applications
• Three Weldon flats on shank prevent rotation in side-lock holders and standard chucks

Compatibility

Designed as an OEM-style general-purpose drill bit compatible with 1/2 inch keyed and keyless drill chucks, Weldon-style side-lock holders, and standard drill press spindles accepting 1/2 inch shank tooling. Suitable for drilling ferrous metals, aluminum, copper, magnesium, nickel, titanium, and synthetic materials per Series R57 application data.

Installation Notes

Installation is performed by qualified machinists, maintenance technicians, or trade professionals using a drill press, hand drill, or milling machine with a compatible 1/2 inch chuck or Weldon side-lock holder. Ensure the spindle is fully stopped and the chuck or holder is securely locked before beginning a cut. Follow applicable shop safety standards and use appropriate PPE including eye protection and chip guards when drilling metal. Do not exceed the recommended feed and speed ratings for the workpiece material.
