Import BDNA-20936 Reduced Shank Drill Bit Set 15 Pc Hss

Product Description

The IMPORT BDNA-20936 is a 15-piece reduced shank drill bit set designed for metalworking and multipurpose drilling applications. Each bit is machined from high-speed steel and finished with a gold oxide coating that helps resist heat and wear during repeated use. The set covers bit sizes from 1/16 inch up to 1/2 inch in 1/32-inch step increments, with a uniform 3/8-inch reduced shank diameter that fits standard drill chucks without requiring a full-shank chuck size. The 135-degree split point angle reduces walking on entry and suits drilling into steel, aluminum, and similar materials. All 15 bits are housed in a metal storage case.

This set is suited for trade professionals and skilled tradespeople who need a broad range of drill sizes on the job. The reduced shank design allows larger-diameter bits to seat in a standard 3/8-inch chuck, making the set practical for use with common corded or cordless drills already on the truck or in the shop. Typical applications include metalworking fabrication, mechanical assembly, and general-purpose hole-making across residential and light commercial job sites.

Installation Notes

Secure the shank fully in the chuck and verify the chuck is tightened before drilling. Always wear appropriate eye protection when drilling into metal. Use cutting fluid or a suitable lubricant when drilling ferrous metals to reduce heat buildup and extend bit life. Inspect bits for wear or chipping before each use and replace any damaged bit before continuing work.
