SDS Drill Bits 10mmx210mm Blue/Grey Pouch Sandy Finish Starex Brand

Starex Sandy Finish SDS Drill Bits are designed with a unique full carbide head and helix design to drill faster than any other drill bits in concrete, brick, masonry and more. Masonry bits typically are used with a hammer drill, which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the drill bit tip, and the rotating flutes carry away the dust. Rotating the bit also brings the cutting edges onto a fresh portion of the hole bottom with every hammer blow. Hammer drill bits often use special shank shapes such as the SDS type, which allows the bit to slide within the chuck when hammering, without the whole heavy chuck executing the hammering motion. Masonry bits of the style shown are commonly available in diameters from 3 mm to 40 mm. For larger diameters, core bits are used. Size of drill bit is 10 mm diameter and 210 mm height.View moreView less
