The Bosch PRO S1237BEF is a bi-metal reciprocating saw blade engineered for cutting medium to thick-walled metal pipes and steel profiles, lasting up to 5x longer than the Bosch S922AF blade. Constructed with a hardened high-speed steel (HSS) tooth strip bonded to a robust carbon steel body, this bi-metal design delivers the ideal balance of cutting hardness and blade flexibility. The curved tooth profile increases contact with the material, producing a cleaner, more controlled cut with reduced vibration. The 3x3 tooth geometry features three varying tooth sizes, gullet depths, and spacing configurations — combining 14, 16, and 18 TPI — to optimise cutting efficiency across the recommended material thickness range of 2mm to 6mm. At 1.1mm thick and 300mm in length, the blade offers added rigidity to help maintain straight, accurate cuts through metal sections. Suitable for metalworkers, electricians, and renovation contractors working with steel pipes, box sections, and metal profiles, this blade fits all S-shank reciprocating saws, making it a versatile addition to any recip saw kit.
