These 78mm Long-Life bi-metal blades are very durable, use for cutting hard and soft wood, laminate, plasterboards, GRP and plastics. The sharp milled HSS teeth have a greater resistance to light contact with brick etc than high carbon steel blades and should last up to three times longer. Cutting cleanly, the tooth ensures a smoke free, no-burn cut especially on material such as MDF. Long 78mm cut length, 32mm width. Single or packs of 5. The blades are offset so that they can be used to make flush cuts if needed. SuperCut hexagonal fitting. FEIN 162 and 163 series.
