Bosch 2608658999 Expert Progressor for Metal S 1137 HBF reciprozaagbladen, 225 mm, 1,1 mm, 25-pack

Reciprocating saw blades for thick metal deliver fast, precise cuts in steel, stainless steel, non-ferrous metals, and cast iron. The Bosch Expert Progressor for Metal S 1137 HBF blade features a patented 2x2 tooth geometry that combines aggressive cutting with long life, making it ideal for demolition and renovation work on pipes, profiles, and solid metal up to 12 mm thick.

Advantages

The bi-metal construction joins a high-speed steel tooth strip to a flexible alloy steel body, giving the blade both hardness and break resistance. The 2x2 tooth pattern alternates between two tooth shapes to reduce vibration and heat buildup, while the 2.5/3.2 mm variable pitch (8/10 TPI) ensures smooth cutting in thick materials. With a universal 1/2-inch shank, these blades fit all major reciprocating saw brands.

Suitable for

• Thick metal pipes and profiles (4–12 mm wall thickness)
