Triumph Twist Drill 090518 Jobber Drill Bit Set 15pc Hss

Product Description

The TRIUMPH TWIST DRILL 090518 is a 15-piece jobber length drill bit set machined from high-speed steel (HSS) with a bright, uncoated finish. The set covers fractional sizes from 1/16 inch through 1/2 inch in 1/32-inch step increments, giving technicians and tradespeople a complete run of common hole sizes in a single kit. All bits feature a standard 118-degree point angle and straight shank geometry, which seat correctly in standard drill chucks without modification. The included metal storage case keeps bits organized and protected between uses. General-purpose construction makes this set suited to repetitive production work and everyday field use alike.

This set is designed for metalworking applications and functions equally well as a multipurpose drilling solution across a range of materials encountered in HVAC, plumbing, electrical, and general mechanical work. The T18 series jobber length profile provides enough flute length for most through-hole and tap-prep operations without sacrificing rigidity. The 1/2-inch maximum hole size covers the majority of common trade fastener and conduit-fitting clearance requirements. The set ships as a single unit in a protective metal case, ready for bench or truck-box storage.
