BOSCH WIERTLO SDS-MAX SPEED 40*520

The SDS max-7 Drill Bit is ideal for use at the highest drilling speeds. Its solid carbide S-cutter and inclined side cutters enable very fast drilling.

This product is intended for use in concrete and reinforced concrete, limestone and masonry. It is compatible with rotary hammers with SDS max holders. 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.
