The best results when processing hard substrates. The DIA Hard-D130-ST milling disc for the RG 130 with a diamond segment height of 5 mm is suited to smaller surfaces on a hard substrate. Thanks to the use of high-quality materials and the segment height, the milling disc has a long service life. Easy disc change in just a few steps|Fast milling off for very hard substrates thanks to a diamond segment height of 5 mm|First-class materials and the segment height ensure a long service life.
