Import BDNA-20935 Reduced Shank Drill Bit Set 29 Pc Hss

Product Description

The IMPORT BDNA-20935 is a 29-piece reduced shank drill bit set engineered for metalworking and general-purpose drilling applications. Each bit is manufactured from high speed steel (HSS) with a gold finish oxide coating that provides lubricity and helps resist heat buildup during operation. The set covers sizes from 1/16 inch through 1/2 inch in 1/64-inch step increments, giving technicians and tradespeople a comprehensive range for a wide variety of hole sizes. All bits feature a 135-degree split point for fast penetration and reduced walking on startup. The 3/8-inch reduced shank allows the full size range to run in standard three-jaw chucks without requiring a larger chuck.

This set is suited for metalworking, fabrication, maintenance, and multipurpose drilling tasks in both shop and field environments. The reduced shank design makes the larger-diameter bits accessible on drills with a 3/8-inch chuck capacity, extending the usable range without a chuck upgrade. The 29 bits store in an included plastic index case for organized access and job-site portability. This set fits the needs of electricians, plumbers, HVAC technicians, and general maintenance personnel who require a full fractional inch drill index on hand.
