BOSCH 9-piece HSS bi-metal universal hole saw set 2608580862

The SDS plus-7X drill bit offers excellent service life when drilling in reinforced concrete. Its 4-cutter full head is made of the highest quality carbide, which reinforces the head and provides exceptional impact resistance. Its continuous distribution of drilling force guarantees that there is no loss of power, which increases the overall service life. Bosch's unique diffusion welding technology (IDS) provides a strong grip between the head and neck. In addition, the 4-spiral design with wide channels reduces wear on the drill bit by ensuring effective removal of drill dust. This drill bit is designed for use with rotary hammers in masonry, concrete and reinforced concrete. In order to achieve precise results, the wear marking indicates whether the hole diameter is still within the tolerance for the dowels. As proof of quality, the drill bit bears the PGM Masonry Drill Bit Association Board quality test mark, which guarantees conformity with strict tolerances, precise drilling and a firm hold of the fixing materials. It is manufactured in Germany.
