It is impossible to create every belt size and every part number but we can make them. Please contact us to receive a quote on the belts to fit your machine. The most common grit size used to create a 240 grit satin finish on sheet is 80 grit (yes we know it is not 240 grit!!) Material Options: KP949 - Strong F weight paper backed aluminium oxide cloth belts. Use when you have a clean, descaled stainless steel sheet and it is a low aggression application. KP950 - Strong F weight paper backed zirconia cloth belts. Use where a higher cut and abrasive life is needed than with KP949 FX87 - Heavy duty polyester backed ceramic abrasive cloth belts. Where high aggression is needed. Will cut through mill scale very effectively.
