Using the correct material is an important part of manufacturing slitting saws and knife correctly. Because It is easily broken by the impact of machines. Traditionally, K series(ISO standard) are widely aceepted. But more new series like super micro grain sizes tungsten carbide material make it possible to have long products liefe and and good flexibility. Kumha adopt world famous tungster carbide with good grade. Also, with the help of Walter CNC made in Germany, we can regulate the thickness of knife or slitting saw up to 0.1mm and the tolerence of thickness is +/-  1/1,000mm.
