SDS Plus Drill Bit Hammer Drill for Concrete Masonry Wall Rock

SDS drill

Generally, a rotary hammer drill or roto hammer is called an SDS drill. Standing for Slotted Drive System, an SDS drill bit has slots along the shank. This means when it is placed in the drill, it creates a stronger connection which results in less tightening when being used.

The SDS tool holder has two distinct advantages when compared to regular hammer drills with 3 jaw chucks.

1. The slotted drive ensures that the drill bit doesn't slip inside the chuck.
2. The slots allow the drill bit to move forward and back during the hammering action.

You simply place the shank of the SDS bit into the SDS holder, rotate it slightly to align the slots until you can push the bit in. Once the shank goes inside, the spring-loaded chuck will secure it without the need for additional tightening. It speeds up the process of drilling because less time is spent tightening and then retightening when the drill is being used.SDS drill shanks are especially well suited for masonry drill that hammer into concrete and stone. This is because the drill can move back and forth inside the chuck in the same manner as a piston. All this while the drill is still held securely so that it doesn't fall out or loosen when rotated.
