"Lasts up to 50 times longer than a bi-metal blade in tough materials - Many blades that are supposedly "multi-material" work well in wood and soft metal. However, they cannot cut harder elements such as screws or metal fittings. The Expert 'Multi Material' has no problems with this: its carbide teeth can cut the hardest types of steel time and time again. The Bosch Expert 'Multi Material' reciprocating saw blade is a good solution to the problem of blades that just don't hold up well enough on the modern construction site. It is a reliable partner that cuts more than just metal and wood. Plastics, composites and prefabricated elements used on construction sites are reliably cut thanks to Bosch Carbide Technology. The progressive tooth pitch is designed to cut thin and thick materials equally. Because the Bosch Expert 'Multi Material' reciprocating saw blade lasts so much longer and performs well in any material, it is of great value to professionals. They achieve more productivity in their work and need to buy fewer blades. Suitable for all S-shank reciprocating saws, sometimes also called tear-off saws. Tooth design: set, ground, Tooth pitch [mm] / TPI: 6-8, 3.0-4.0, 6-8, Total length [mm]: 150, 6, Width [mm]: 25, Thickness [mm]: 1.25, Material: CARBIDE, CT, HCS, 100, Applications: Wood with (hardened) nails/metal (5-100 mm), Wood with steel parts (5-100 mm), Cast iron pipes (diameter < 3""/75 mm), Glass fibre reinforced(s) plastic/epoxy resin (<100 mm), Type: S 956 XHM"
