The Bahco PC-22-INS is a 22 inch/550 mm handsaw with waved toothing. The WT-toothing is specially designed for cutting insulation material with the blade being re-sharpenable with any regular knife sharpener. The blade has a thickness of 0.83mm which is equal to other common saws. The PC-22INS has a comfortable two component handle and a unique rust-protective sleeve. The blade is not treated with clear varnish (as in Bahco's regular handsaws) nor with powder coating as both influence the performance of the saw due to friction and bluntness of the saw. The sleeve is impregnated with a Volatile Corrosion Inhibitor* (VCI) that will protect the saw from corrosion. The ProfCut Insulation handsaw has been tested on all sorts of insulation materials and gives excellent finishing with low friction and creates less saw dust. The most common international materials for insulation are Mineral wool or Glass wool. EPS Expanded Polystyrene. XPS Extruded polystyrene. Stone wool or Rock wool.
