Triumph Twist Drill 090595 Reduced Shank Drill Bit Set

Product Description

The TRIUMPH TWIST DRILL 090595 is an 8-piece reduced shank drill bit set engineered for heavy-duty metalworking and multipurpose drilling applications. Built from high-speed steel (HSS) with a black oxide and bronze oxide finish, the bits resist heat and wear during extended use. The set covers a range from 9/16 inch to 1 inch in 1/16 inch step increments, with a 118-degree split point that self-centers on contact to reduce walking and improve hole accuracy. All bits feature a reduced 1/2 inch shank diameter, allowing them to chuck into standard 1/2 inch drill chucks even at the larger bit sizes. The included plastic storage case keeps bits organized and protected between uses.

This set is suited for metalworking and multipurpose drilling tasks in industrial, commercial, and shop environments. The reduced shank design makes large-diameter drilling accessible on standard 1/2 inch chuck equipment without requiring specialty tooling. Typical applications include drilling through steel plate, structural members, and similar ferrous and non-ferrous materials where hole sizes in the 9/16 inch to 1 inch range are required. The T98FHD series is built to heavy-duty performance standards and is commonly used by machinists, maintenance technicians, pipefitters, and fabricators.

Installation Notes

Secure each bit fully into a 1/2 inch chuck before operation and confirm the chuck key is removed before starting the drill. Apply cutting fluid or lubricant when drilling through ferrous metals to extend bit life and improve cut quality. Use appropriate workholding to secure the material and prevent rotation. Wear eye protection and follow all applicable shop safety standards when operating drilling equipment.
