Triumph Twist Drill 011199 Hss Drill Bit Set 29 Pc

Product Description

The TRIUMPH TWIST DRILL 011199 is a 29-piece jobber length drill bit set made from high-speed steel (HSS) for general-purpose metalworking and multipurpose drilling applications. The set covers fractional inch sizes from 1/16 inch to 1/2 inch in 1/64-inch step increments, giving technicians and tradespeople a complete range of common hole sizes in a single case. Bits feature a bright/uncoated finish, straight shank, and a 118-degree standard point angle. The T17L series construction balances durability and cutting performance across a wide range of materials encountered in trade work. The metal storage case keeps bits organized and protected between uses.

This drill bit set is suited for metalworking and multipurpose drilling tasks in both residential and commercial trade environments. Electricians, HVAC technicians, plumbers, and general contractors will find the 1/16-inch to 1/2-inch fractional range covers the majority of common field drilling needs. The 4.125-inch overall length is consistent with standard jobber length geometry, making these bits compatible with most portable and bench-mounted drill drivers. Left-hand cutting direction makes these particularly useful for removing broken fasteners and extracting stripped screws.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with rotary cutting tools and applicable shop or jobsite safety practices. Always secure the workpiece before drilling and confirm the drill chuck is properly tightened on the straight shank before operation. Use appropriate cutting fluid or lubricant when drilling metals to extend bit life and improve hole quality. Inspect bits for wear or damage before each use and replace any bit that shows cracking, excessive dullness, or shank deformation.
