Triumph Twist Drill 094136 Reduced Shank Drill Bit

Product Description

The TRIUMPH TWIST DRILL 094136 is a reduced shank drill bit engineered for professional drilling applications in metal and other materials. The bit features a 9/16 inch cutting diameter with a 1/2 inch Weldon shank, allowing it to seat securely in compatible chucks and holders. Constructed from high speed steel (HSS), it delivers consistent performance across repeated use cycles. The 118-degree split point promotes accurate hole starts and reduces walking on entry. With a 6 inch overall length and maximum drilling depth of 3 inches, this bit suits a range of through-hole and blind-hole applications commonly encountered in HVAC, plumbing, and electrical rough-in work.

This drill bit is suited for trade professionals who need a reduced shank configuration to fit standard 1/2 inch chucks while drilling 9/16 inch diameter holes. The Weldon shank with three flats prevents slippage under torque load, making it reliable for high-cycle production drilling or repetitive field work. The right-hand, spiral flute geometry promotes chip evacuation during drilling in steel, cast iron, and similar ferrous materials. It is sold individually and is appropriate for use with standard drill presses or hand-held power drills equipped with a 1/2 inch chuck.

Installation Notes

Install and remove this bit with the drill or press fully powered down and the chuck key secured away from the machine. Verify the Weldon shank is fully seated in the chuck and that all flats are engaged before applying power. Use appropriate cutting fluid or coolant when drilling hard metals to extend bit life, noting this bit is not configured for through-coolant delivery. Follow applicable OSHA machine guarding and PPE requirements when operating drilling equipment.
