The tin countersink CD15 with back perforation is used for controlled dust extraction in inhabited rooms. Very good cooling of the segments and significant wear reduction through immediate extraction of the chamber. The diamond tin countersink runs easily and doesn't get stuck due to less friction on the outer wall. Dust exposure significantly reduced.Machine suitability: The cans countersink CD15 is suitable for manual use with the drill. He can fully play his strengths on machines of all power classes. Material suitability: The CD15 has been specifically developed for the machining of concrete, pavers, medium-hard marble tiles, sandstone and hollow blocks.This Rhodius quality tool is also very suitable for the machining of soft concrete stone. Construction and production: The CD15 tin core with back punching enables a controlled dust removal. In inhabited rooms, dust can thus be considerably reduced. The immediate extraction of the waste space simultaneously reduces friction and cooler segments. The result: Significantly less wear. Due to the low friction on the outer wall, the diamond core does not run any more easily and does not jam. The tool is tested according to EN13236 and OSA.Thanks to the high-quality industrial diamonds the CD15 is especially powerful. The core is laser-welded. Dimensions: This can countersink is available in diameters from 68 mm to 82 mm.This text is machine translated.
