Triumph Twist Drill 099820 Jobber Drill Bit Set 60 Pc

Product Description

The TRIUMPH TWIST DRILL 099820 is a 60-piece jobber length drill bit set sized by wire gauge from number 60 through number 1. Each bit is machined from high-speed steel with an oxide finish and features a 118-degree standard point angle and a straight shank. The set is designed for general-purpose metalworking and multipurpose drilling applications. Bits are stored in a metal case that keeps each size indexed for fast retrieval on the job. At 1.6 pounds, the complete set is compact enough to carry in a tool bag without adding significant weight.

This set covers the full wire gauge range from number 60 to number 1, making it well suited for machinists, maintenance mechanics, electricians, and HVAC technicians who regularly drill pilot holes, clearance holes, and access holes in sheet metal, bracket stock, and light structural material. The jobber length geometry balances reach and rigidity for use in standard drill presses and portable hand drills. The inch-based sizing system matches common tap-and-drill charts used in trade work.

Installation Notes

Secure the workpiece firmly before drilling to prevent movement and bit breakage. Ensure the drill chuck is fully tightened and the shank is seated completely before operation. Use appropriate cutting fluid when drilling harder metals to extend bit life. Inspect each bit for wear or damage before use and replace any bit that shows chipping or excessive dulling at the cutting edges.
