DIN 338 Hex Shank HSS Drill Bits
Product Show
The material is a high-speed steel that has been heat treated to create high hardness, tensile strength and an extremely long cutting life. In addition to being sharp and preventing slipping, this tip design is also highly stable and precise, resulting in a long drilling life. It is ideal to use these handy little short drill bits with an angle drill/angle wrench equipped with a 1/4-inch hex chuck, which is stiffer and will not bend as much as a longer drill bit. Designed with a shorter length, this product is ideal for corner locations and tight spaces that are difficult to reach.
Has a standard tapered chisel edge. Chip flutes and highly rounded rear edges. Specifically designed for metal drilling ensuring precise, clean holes. The rotating design greatly improves drill bit performance and is optimized for efficiency to increase drilling speeds. Special surface treatment prevents rust and wear. The hex shank reduces rotation in the chuck, and the bit shank is marked for easy size identification. This drill reduces thrust force by 50% when you have a specific hole size. True running accuracy for perfectly round holes.
