Triumph Twist Drill 094150 Reduced Shank Drill Bit Hss

Product Description

The TRIUMPH TWIST DRILL 094150 is a reduced shank drill bit designed for drilling operations that require a larger bit diameter than the available chuck capacity allows. The bit measures 25/32 inch (0.7812 inch) in diameter with a 1/2-inch Weldon shank, giving it compatibility with standard 1/2-inch chucks and holders. Built from high speed steel with a coated finish, it delivers dependable wear resistance across a range of metal and fabrication applications. Overall length is 6 inches with a maximum drilling depth of 3 inches. The 118-degree split point reduces walking on entry and improves centering without a pilot hole. Licensed trades, machinists, and maintenance professionals are the primary installers.

This bit is suited for residential and commercial fabrication, maintenance, and mechanical work where a 25/32-inch hole is required and only a 1/2-inch chuck is available. The Weldon shank with 3 flats prevents the bit from rotating in the holder under load, making it appropriate for drill presses, milling machines, and magnetic drill setups. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling in ferrous and non-ferrous materials.

Key Features

• 25/32-inch (0.7812-inch) cutting diameter with 1/2-inch reduced Weldon shank for standard chuck compatibility
• 118-degree split point for accurate entry and reduced thrust force
• High speed steel construction with coated finish for extended service life
• 3-flat Weldon shank prevents slippage under torque load
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• Maximum drilling depth of 3 inches

Compatibility

Designed for use with 1/2-inch Weldon-style holders, drill presses, and magnetic drills requiring a reduced shank configuration for the T9FHD series bit profile.

Installation Notes

Installation is performed by machinists, maintenance technicians, or qualified tradespeople familiar with rotary cutting tools. Secure the Weldon shank firmly in the holder so all three flats are properly engaged before operation. Ensure the machine is fully de-energized and the chuck or holder is locked before changing bits. Use appropriate cutting fluid or coolant as required by the base material, and never exceed the rated drilling depth of 3 inches.
