Triumph Twist Drill 094142 Reduced Shank Drill Bit Hss

Product Description

The TRIUMPH TWIST DRILL 094142 is a reduced shank twist drill bit manufactured from high speed steel with a coated finish. It features a 21/32 inch (0.6562 inch) cutting diameter paired with a 1/2 inch Weldon shank, allowing it to seat in standard 1/2 inch chucks and tool holders without a full-diameter shank. The 118-degree split point reduces walking on entry and lowers thrust requirements. At 6 inches overall length with a maximum drilling depth of 3 inches, this bit is suited for production drilling and maintenance work in metal fabrication, mechanical shops, and industrial maintenance environments.

This bit is designed for right-hand cutting in ferrous and non-ferrous metals, including mild steel, cast iron, aluminum, and similar materials. The Weldon shank with three flats provides positive drive engagement, preventing shank slippage under torque. It is commonly used in drill presses, milling machines, and mag-base drills where a 1/2 inch tool holder is standard. The T9FHD series targets general-purpose production drilling where a standard jobber-length bit lacks the shank diameter compatibility required by the machine spindle.

Key Features

• 21/32 inch (0.6562 inch) cutting diameter with reduced 1/2 inch Weldon shank
• 118-degree split point for reduced walking and lower feed force on entry
• High speed steel construction for durability in metal drilling applications
• Weldon shank with 3 flats for positive rotational drive and slip resistance
• 6 inch overall length with 3 inch maximum drilling depth
• Coated finish for improved wear resistance and chip evacuation

Compatibility

Designed for use in drill presses, milling machines, and magnetic-base drills equipped with 1/2 inch Weldon-style tool holders or end mill holders. Part of the TRIUMPH TWIST DRILL T9FHD series.

Installation Notes

Installation is performed by machinists, toolroom technicians, or industrial maintenance mechanics. Secure the Weldon shank fully into the tool holder so that at least one flat aligns with the set screw before tightening. Ensure the machine spindle is fully stopped and locked out before changing bits. Do not exceed the recommended feed rate for the work material and bit diameter to avoid premature edge failure.
