Triumph Twist Drill 094140 Reduced Shank Drill Bit

Product Description

The TRIUMPH TWIST DRILL 094140 is a reduced shank twist drill bit designed for precision hole-making in metal and industrial applications. It features a 5/8 inch cutting diameter with a 1/2 inch Weldon shank, allowing it to seat securely in standard chuck sizes without requiring a larger spindle bore. The bit is manufactured from high speed steel with a coated finish for improved wear resistance. A 118-degree split point tip reduces walking at the start of a cut and lowers required feed force. Overall length is 6 inches with a maximum drilling depth of 3 inches. This bit is sold individually and is suited for professional machining, fabrication, and maintenance environments.

This drill bit is a practical choice for production shops, maintenance facilities, and job-site fabrication work where a larger diameter hole is needed but the available toolholder or drill press chuck is limited to a 1/2 inch shank. The Weldon flat shank with three flats prevents slippage under torque during interrupted or heavy-feed drilling operations. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling. The T9FHD series is a standard reduced shank configuration used across general metalworking and light industrial drilling tasks.

Key Features

• 5/8 inch cutting diameter with 1/2 inch Weldon reduced shank for use in standard half-inch chucks
• 118-degree split point tip reduces bit walking and improves cut initiation
• High speed steel construction provides durability across a range of metals
• Three-flat Weldon shank prevents rotational slippage under load
• Coated finish extends tool life by reducing friction and heat buildup
• Right-hand spiral flutes with regular helix promote consistent chip evacuation

Compatibility

Designed as a reduced shank replacement for standard 1/2 inch chuck drill presses, magnetic drills, and hand drills requiring a 5/8 inch cutting diameter in the T9FHD series configuration.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Ensure the drill press, magnetic drill, or hand drill is powered down and locked out before changing tooling. Secure the Weldon shank firmly in the chuck or toolholder so that at least one flat is positively engaged by the set screw. Do not exceed the recommended maximum drilling depth of 3 inches per pass without retracting to clear chips.
