The Bosch PRO S1137EAF is a bi-metal reciprocating saw blade designed for precise cutting of thin-wall metal pipes, profiles, and steel fittings, lasting up to 3x longer than the Bosch S922AF blade. Constructed with a hardened high-speed steel (HSS) tooth strip bonded onto a high carbon steel (HCS) body, this bi-metal design delivers the ideal combination of a hard cutting edge and a flexible, robust body. The result is a blade that resists tooth wear during demanding metalwork applications, making it well suited to metalworkers, renovators, and electricians working with steel pipework and profiles. The S1137EAF features a distinctive 3x3 tooth geometry, with varying tooth and gullet sizes across a 20+22+24 TPI pitch range. This multi-progression design optimises chip clearance and cutting efficiency across the recommended material thickness range of 1mm to 3mm. The curved tooth section further improves blade-to-material contact for a smoother, more accurate cut. At 225mm total length with a 175mm maximum cut capacity and 1.1mm blade thickness, this is a capable blade for controlled cutting in thin metal. It fits all standard S-shank reciprocating saws.
