Products > Steel wool machines Steel Wool Knives Our specially hardened steel wool knives are optimally designed for processing steel and stainless steel wool, guaranteeing the highest precision and a long service life. For the production of steel wool, we recommend blades made from special chrome blade steel, whilst for stainless steel wool, the use of high-speed steel blades is ideal. A special hardening process, followed by the precise grinding of the desired profile, reliably prevents warping or bending of the surfaces and ensures consistently high quality. We recommend: Steel wool: to use of steel wool knives made of special-chrome knife steel Stainles steel wool: to use of steel wool knives made of high-speed steel Advantages of our manufacturing method: First, our knives are hardened by means of a special hardening process, then the wished number of grooves to be ground no distortion of the surface no bending Standard knife dimensions Standard Y Z X 58 mm x 8 mm x 120 mm 70 mm x 10 mm x 120 mm 90 mm x 10 mm x 120 mm 120 mm x 10 mm x 120 mm 200 mm x 10 mm x 120 mm Special dimmensions on request Standard grooves Standard Number Division in mm Grooves per inch 0000 0.06 425 000 0.08 320 / 280 00 0.10 250 0 0.12 220 / 210 / 200 1 0.15 180 / 160 2 0.18 140 4 0.30 80 5 0.40 64 6 0.50 50 7 0.65 38 8 0.80 32 9 1.00 24 10 1.20 Special grooves on request
