Tyrolit Vincent recently introduced the MR2 diamond saw blade for cutting marble and limestone. The blade can be used on multi-head cutting machines and bridge mills, according to its manufacturer. The segments in the saw blade are produced by laser cutting, starting from a continuous rim blade. The combination of laser cuts and a sintered core has resulted in superior alignment of the diamond segments, giving the benefit of extreme precision, according to the company. This type of cut helps to lubricate and cool the segments. The hook ends of the teeth considerably reduce the noise level and are at an angle that minimizes the stress created on the edge of the teeth. MR2 has a 9-mm diamond segment. It is available in two versions -- 300 diameter with 23 segments and 350 diameter with 27 segments. Both versions have a standard sintered core.
