Bosch PRO S1237EAF Thin Metal Reciprocating Saw Blade

The Bosch PRO S1237EAF is a bi-metal reciprocating saw blade designed for clean, precise cutting of thin-wall metal pipes, profiles, and steel fittings — lasting up to 3x longer than the Bosch S922AF blade.

Built for metalworkers, electricians, and renovation contractors, this blade is ideally suited to tasks where a neat, controlled cut is essential. The 300mm blade handles material thicknesses between 1mm and 3mm, making it well matched to thin-section steel tube, conduit, and sheet metal profiles.

The bi-metal construction bonds a hardened high-speed steel (HSS) tooth strip to a tough carbon steel body, combining cutting performance with flexibility and resistance to breakage. The curved tooth profile improves contact with the workpiece for a smoother finish, while the 3x3 tooth geometry — with variable tooth pitch of 20, 22, and 24 TPI — optimises chip clearance and cutting efficiency across the material range.

Compatible with all S-shank reciprocating saws, this blade fits standard tool-free blade clamps from all major manufacturers, making it a straightforward addition to any site toolkit.
