Masonry Drill Bit 7/8 in x 17 in x 21 in SDS-Max

SDS max carbide bits feature the SDS max drive system for quick bit changes and efficient power transfer from the hammer to the bit. Bits larger than 5/8 in. (9/16 in.) feature the highest quality carbide and two additional carbide tips, resulting in four cutting edges. These four cutting edges increase drilling speed by pulverizing more concrete. They also provide a rounder hole than with two cutters. Flutes quickly clear concrete dust from deep holes, which increases drilling speed. For use only with SDS max hammers. SDS max bits are also available in metric sizes. One per package.
