The HEX SHANK MASONRY DRILL BITS are made from high grade steel using high quality tungsten carbide, machine welded tips for long life.
These bits are ideal for drilling holes in concrete and masonry materials. 
The masonry drill bits feature a 2-cutter head for more accurate starting of holes.
The quick change HEX shank masonry drill bit features a 1/4” inch (6.35mm) HEX shank design to prevent bit spinning and slippage.
This also allows for quick and convenient bit changes when using impact drivers.
