Durable cutting of composite wood and wood with metal. Aggressive 3-TPI carbide teeth on the top of the blade for backward cuts. For firefighters, rescue services, police, and medical emergency services, it is crucial to quickly access locked areas. One of their most important rescue tools is reciprocating saws - however, they require exceptional saw blades that can reliably cut through composite wood, windows, and wood with hardened nails and screws. The EXPERT Multi Material Demolition S681KLHM is designed for this critical task. The Bosch EXPERT Multi Material Demolition S681KLHM is based on Bosch Carbide Technology. It cuts quickly and reliably through hard materials like composite wood and wood with hardened metal fasteners. Outstanding lifespan thanks to Bosch Carbide Technology.
