Triumph Twist Drill 090560 Drill Bit Set 115 Pc Hss

Product Description

The TRIUMPH TWIST DRILL 090560 is a 115-piece jobber length drill bit set built for general-purpose metalworking and multipurpose drilling applications. The set covers a wide size range in the inch measurement system, from 1/16 inch fractional up to 1/2 inch fractional, spanning wire gauge sizes #60 through #1 and letter sizes A through Z. All bits are manufactured from high-speed steel with a bright, uncoated finish and feature a standard 118-degree split point. Shank type is straight on all included bits. The storage case is metal construction, keeping the full 115-piece inventory organized and protected on the job or in the shop.

This set is suited for licensed electricians, plumbers, HVAC technicians, and general tradespeople who need a comprehensive drill index on hand for field or shop use. The Series T123 bits are sized for metalworking but perform across multipurpose drilling tasks including wood, plastics, and light-gauge metals. Step increments progress in 1/64-inch intervals through the fractional range, providing close size resolution for precise hole sizing. Minimum hole size starts at 0.06 inches and the set reaches a maximum hole diameter of 0.5 inches.
