Holds up to 50 times longer than a bi-metal blade in robust materials. Cutting out windows for replacement or during demolition has always been a challenging task, especially when multiple window materials like steel-reinforced wood or plastic had to be sawed. As high-strength construction steel has become increasingly common for window fixing screws, the old bi-metal blades could no longer penetrate a single screw. The Bosch Expert 'Window Demolition' reciprocating saw blade is designed for modern window dismantling. Thanks to Bosch Carbide Technology, it features teeth that can penetrate the toughest and strongest fixing screws and withstand them. The short, tapered tips and laterally set carbide teeth are all designed for specific tasks: this blade is our specialist for windows and doors—whether made of wood, plastic, or composite materials. With its combination of durability, efficiency, and the ability to perform window or door demolition work, the Bosch Expert 'Window Demolition' reciprocating saw blade is highly popular among window builders. It even withstands contact with masonry, mortar, and plaster. Suitable for all S-shank reciprocating saws, which are sometimes referred to as demolition saws. Tooth design: ground, tooth pitch: 4.3 / 6, 4, 6, total length: 150, width: 25, thickness: 1.25, material: carbide, CT, HCS, 100, application areas: window demolition.
