These bits are generally used for making heavy-duty jobs in tough materials much easier to complete. They have a special shank design that ensures a more powerful hammer action and enables quick and easy bit changes.

They have a different shank design to standard straight-shank masonry bits: 10mm diameter, with two open grooves held by driving wedges, and two closed grooves held by locking balls.
When using standard masonry bits the whole chuck is moved to create the hammer action, but one advantage of SDS masonry drill bits is that the bit moves backwards and forwards inside the chuck to add to the hammer action. This means that the bit can be hammered much harder, which makes drilling through tough materials much easier with much less force required.
Another advantage of SDS masonry bits is the speed at which they can be changed; you simply push the bit into the chuck and it locks automatically. Removing it is just as easy – simply pull the release ring or push a button to disengage the locking mechanism!
