Bosch PRO S1237HBF Thick Metal Reciprocating Saw Blade

The Bosch PRO S1237HBF is a heavy-duty bi-metal reciprocating saw blade engineered for cutting thick-wall metal pipes, profiles, and steel fittings — delivering up to 5x longer life than the Bosch S922AF blade.

Constructed with a hardened HSS tooth strip bonded to a flexible carbon steel body, the S1237HBF combines cutting hardness with structural resilience. The bi-metal welding process ensures the blade resists breakage during demanding cutting tasks, making it a reliable choice for metalworkers, renovators, and electricians working with structural steel and pipework.

The 3x3 tooth geometry features varying tooth and gullet sizes across three pitch configurations (10, 12, and 14 TPI), optimising chip clearance and cutting efficiency. The curved tooth section improves material contact throughout each stroke, resulting in a smoother, more controlled cut. A 1.1mm blade thickness adds rigidity to support straight, accurate cuts in material from 4mm up to 12mm thick.

Compatible with all S-shank reciprocating saws, this blade is suitable for a wide range of tools on site. Ideal for plumbers and pipefitters working with thick-bore pipework, electricians cutting steel conduit, and fabricators tackling structural metal profiles.
