The Mafell 092616 KSB-SP 280 is a premium 280mm circular saw blade engineered specifically for cutting composite and sandwich panels. Featuring a specialized Alternate Top Bevel with Chamfer (WZ/FA) tooth geometry, this blade easily cuts through structural insulated panels (SIPs), sandwich boards with insulating cores, and composite panels with steel or aluminum decking shells.

Built with high-quality tungsten carbide (HW) teeth, the KSB-SP series provides exceptional durability and a long service life. Its optimized tooth profile is designed to reduce cutting forces, which not only extends the life of the blade and machine but also maximizes runtime on cordless setups. The blade design minimizes heat build-up and noise emissions while delivering highly improved cut surface and edge quality.

This 52-tooth blade is designed for use with Mafell K 105 and K 105-18 portable circular saws.
