WORKPRO 8-Piece SDS-Plus Rotary Hammer Drill Bit performs precision-drilling in reinforced concrete. A vibration-reduced power transfer from the rotary hammer to the full carbide head is provided by the 2 + 2 flute design, which is made of high-alloy steel and created using optimised hardening technology. This offers the stability necessary for exact results. The bit is intended for use on masonry, concrete and reinforced concrete. It is compatible with rotary hammers with SDS plus holders, Like BOSCH, Dewalt, MAKITA, Milwaukee, etc.
