Features: *Best for drilling in concrete masonry natural stone solid or perforated brick hollow brick etc... or working on all types of bricks it s suitable for both DIY enthusiasts and professionals *This drill has a special shank with a keyway to support the extra torque provided by SDS drills. Narrow sides reduce drag. *The tool holder has the advantage of mounting into a simple spring chuck so just push the drill bit into the chuck no tightening required. This shank and chuck are particularly suitable for hammer drilling in stone and concrete using a masonry drill. *The bit is not firmly fixed in the chuck but slides back and forth like a piston; it does not slip during rotation due to the non-circular shank cross-section that matches the chuck. *The drill s hammer only accelerates the drill itself not the large chuck which makes percussion drilling with SDS shank bits much more efficient than other types of shanks.
