Milwaukee SDS Max adapters are ideal for fast & accurate drilling with the help of a rotary hammer drill. These drill bit adapters feature an SDS shank for fitting into a spring-loaded chuck, allowing hammer drilling in stone & concrete and breaking them into tiny granules with minimum efforts. They come equipped with a rotational drive with sliding keyways to mate with the keys in the chuck, thereby preventing the drill bits to fall out with excessive vibrations and high-torque transmissions. Choose from an extensive range of SDS Max adapters with sizes ranging from 12-1/2 to 82-1/2 inches on Raptor Supplies.
