Product Description

The TRIUMPH TWIST DRILL 099832 is a 115-piece jobber length drill bit set covering a wide range of inch sizes for general-purpose metalworking and multipurpose drilling applications. The set includes high-speed steel (HSS) bits with an oxide finish, straight shanks, and a conventional 118-degree point angle. Sizes span from 1/16 inch to 1/2 inch in fractional increments, wire gauge sizes from number 60 to number 1, and letter sizes A through Z, with 1/64-inch step increments across fractional sizes. All 115 bits store in an included metal case. The set weighs 8.06 pounds.

This drill bit set is suited for professional tradespeople and shop technicians who need a comprehensive selection of HSS jobber length bits on hand for metalworking, HVAC sheet metal work, electrical rough-in, plumbing, and general fabrication tasks. The broad size range reduces the need for multiple specialized sets. The metal storage case keeps bits organized and protected on a job site or in a service vehicle. This is a general-purpose set intended for drilling into steel, aluminum, wood, and similar materials at standard cutting speeds.

Installation Notes

Drill bit sets of this type are installed and used by HVAC technicians, electricians, plumbers, and general tradespeople. Always secure the workpiece before drilling and confirm the chuck is fully tightened before operation. Select the correct bit size for the application and ensure the drill speed is appropriate for the material being drilled. Inspect bits for wear or damage before each use and replace any bit that shows cracking, chipping, or significant wear.
