Hertel 02499515 Reduced Shank Drill Bit Set 29 Pc Hss

Product Description

The HERTEL 02499515 is a 29-piece reduced shank drill bit set made from high-speed steel with an oxide finish. It covers sizes from 1/16 inch up to 1/2 inch in 1/64-inch step increments, with a 3/8-inch reduced shank diameter that fits standard three-jaw chucks even when drilling larger holes. The 118-degree standard point angle is suited for general-purpose drilling in metal, plastic, and wood. This set is designed for trade professionals and skilled tradespeople who need a full fractional inch range on the job site or in the shop.

This drill bit set is intended for metalworking and multipurpose drilling applications in residential, commercial, and light industrial settings. The reduced shank design allows the full 1/16-inch-to-1/2-inch size range to run in drills and drill presses equipped with a 3/8-inch chuck, without requiring a 1/2-inch chuck for the larger bits. HVAC technicians, plumbers, electricians, and general contractors will find the full fractional range useful for sheet metal, conduit, pipe flange, and structural work. All 29 bits store in the included plastic index case.

Installation Notes

Secure the workpiece before drilling and ensure the chuck is tightened fully on the reduced shank before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect bits for chipping or wear before each use and replace any damaged bits promptly. Follow applicable shop-safety and PPE requirements when operating drill equipment.
