SDS Carbide Drill Bits

SDS-Plus Carbide Drill Bits are designed for use in a rotary hammer equipped with an SDS (slotted drive shaft) type chuck. The bits are manufactured to conform with ANSI Standard B212.15 and can be used to drill in concrete, block, brick, and soft stone. Whenever a post-installed concrete anchor is being used to attach a fixture to concrete, a hole is drilled in the concrete. The most popular type of drill bit that is used to drill into concrete is the SDS carbide drill bit.

SDS drill bits are inserted by pushing the bit into the chuck, and held in place by grooves in the bit. No tightening is needed as each bit is designed to fit the chuck exactly. The open grooves allow a rotation action to be applied, while the closed grooves allow the hammer action by using ball bearings to lock the bit in place. It is impossible for the drill bit to slip out of place. They are taken out of the drill via a lock release mechanism. The bit actually hammers back and forth within the chuck. This is why SDS hammer drills deliver more powerful than regular hammer drills. In regular hammer drills the whole chuck needs to move, which wastes power and is less efficient.
