Triumph Twist Drill 099814 13 Pc Jobber Drill Bit Set

Product Description

The TRIUMPH TWIST DRILL 099814 is a 13-piece jobber length drill bit set designed for general-purpose metalworking and multipurpose drilling applications. Built from high-speed steel (HSS) with an oxide finish, the set covers sizes from 1/16 inch through 1/4 inch in 1/64-inch step increments. All bits feature a straight shank, a standard 118-degree point angle, and a jobber length profile, making them compatible with standard drill chucks across a wide range of portable and bench-mounted drills. The metal storage case keeps bits organized and protected on the job. At 0.75 pounds, the set is compact enough for a service van or tool bag.

This set is suited for metalworking trades including HVAC, plumbing, and electrical work where drilling through sheet metal, light-gauge steel, and similar materials is routine. The 13-piece fractional progression handles the most common hole sizes encountered in field service and installation work. The oxide coating provides basic corrosion resistance for shop and field environments. The Series T19B designation identifies the product line within the TRIUMPH TWIST DRILL catalog for reorder reference.

Installation Notes

Drill bit sets of this type are installed and replaced by qualified tradespeople including HVAC technicians, plumbers, and electricians as part of routine tool maintenance. Ensure the drill chuck is fully tightened and the power tool is unplugged or battery removed before changing bits. Use appropriate cutting fluid when drilling harder metals to extend bit life and improve cut quality. Inspect bits for wear or damage before each use and replace any bit that shows cracking, excessive wear at the tip, or distortion of the shank.
