Lasts up to 50 times longer than a bi-metal blade in tough materials. Cutting thin sheet metal and thin-walled pipes can be a challenging task. However, with a good reciprocating saw blade, this is possible. The real problems arise when stainless steel needs to be cut. This tough, high-alloy steel poses difficulties for construction or renovation workers and often destroys the blades. Thanks to Bosch Carbide Technology, these issues are a thing of the past. The Expert 'Thin Tough Metal' represents a breakthrough in the development of reciprocating saw blades. The hardest metal has been integrated into a tooth design optimized for steel sheets and pipes. The teeth are ground to a fine geometry, allowing for smooth cutting of even thin stainless steel sheets. The Bosch Expert 'Thin Tough Metal' reciprocating saw blade is ideal for metalworkers, plumbers, installers, and renovators. It not only handles tasks that were previously nearly impossible but also offers exceptional durability. Suitable for all S-shank reciprocating saws, which are sometimes referred to as demolition saws. Tooth design: Carbide Technology, ground teeth, tooth pitch: 1.4 mm / 18 TPI, total length: 115 mm / 4 1/2 inches, width: 19 mm, thickness: 1 mm, material: Carbide, CT, HCS. Applications: Inox sheets (2-4 mm), Inox profiles (diameter <50 mm), fiberglass-reinforced plastic/epoxy resin (<50 mm). Reduce the stroke rate, work without pendulum action. Use coolant. Type: S 522 EHM.
