Bosch SDS PLUS 9 Speed an Hollow Masonry Drill Bit 20mm 280mm

The SDS plus-9 Speed Clean Drill Bit is available as 4-cutter for bigger diameters and as 2-cutter for smaller diameters and features an accurate centring tip. To achieve accurate results, the visibility of the wear mark indicates if the diameter of the hole is still in tolerance for metal anchor setting. It is made in Germany. It is compatible with rotary hammers with SDS plus shanks and works in combination with industrial M-class vacuum cleaners. The SDS plus-9 Speed Clean Drill Bit allows for dustless drilling. While working, the built-in vacuum attachment pulls dust though extraction holes in the drill bit, allowing optimum material removal without additional steps. This technology results in a clean, dust-free working environment. The bit is intended for use on masonry, concrete and reinforced concrete.
