Lasts up to 50 times longer than a bi-metal blade in tough materials. Many blades that claim to be suitable for multiple materials perform well in wood and soft metal. However, harder elements like screws or metal fittings can’t be cut with them. The Bosch Expert 'Multi Material' has no such issues: its carbide teeth can repeatedly cut through the toughest steel grades. The Bosch Expert 'Multi Material' reciprocating saw blade is a great solution for the problem of blades that simply don't hold up well on modern job sites. It is a reliable partner that cuts more than just metal and wood. Plastics, composites, and prefabricated elements used on construction sites are reliably separated thanks to Bosch Carbide Technology. The progressive tooth design is intended to cut both thin and thick materials equally well. Since the Bosch Expert 'Multi Material' reciprocating saw blade lasts so much longer and performs well in every material, it is of great value to professionals. They achieve greater productivity in their work and need to purchase fewer blades. Compatible with all reciprocating saws with an S-shank.
