Lasts up to 50 times longer than an HCS blade in tough materials. There is softwood, there is hardwood – and then there are those tough woods that destroy saw blades and cause frustration. Wet wood, thick pressure-treated boards, and knotted live roots or thick branches fall into this unpleasant category. The good news: the Expert 'Tough Wood' can cut through them all. The Bosch Expert 'Tough Wood' reciprocating saw blade achieves its outstanding lifespan through Bosch Carbide Technology – the hardest metal is integrated into the tooth structure using advanced design and manufacturing techniques. The extra-large chip spaces ensure very fast chip removal, enabling quick and efficient cuts. Landscape designers, carpenters, and craftsmen will especially appreciate the Bosch Expert 'Tough Wood' reciprocating saw blade. It is so tough and durable that you can cut roots to remove trees and hedges without worrying about the ground and the stones within it. Compatible with all reciprocating saws with an S-shank.
