This rotary hammer/drill has an SDS-plus chuck. SDS-plus drill bits have four large drive/engagement grooves that ensure a stronger connection capable of more rotational torque results. SDS-plus bits range in size from 5 mm to 30 mm or 5/32" to 1-1/4" diameter. The SDS-plus chuck will also accept standard drill bits.
