Bosch PRO S937EAF Thin Metal Reciprocating Saw Blade

The Bosch PRO S937EAF is a bi-metal reciprocating saw blade designed for precise cutting in thin-wall metal pipes, profiles, and steel fittings.

Built for metalworkers, electricians, and renovators, this blade combines a hardened high-speed steel (HSS) tooth strip with a flexible carbon steel body. The bi-metal construction delivers both cutting hardness and blade flexibility, reducing the risk of breakage during demanding recip saw work.

The curved tooth geometry improves contact with the material, producing a smoother, neater cut in thin metal sections. The variable 3x3 tooth pattern — with differing tooth and gullet sizes across three pitch groups — optimises chip clearance and cutting efficiency.

At 150mm in length with a 1.1mm thick body, this blade is well-suited to cutting thin metal between 1mm and 3mm in thickness. Compatible with all S-shank reciprocating saws, it integrates easily with standard recip saw tooling on site.

Features and Benefits:
• Lasts up to 3x longer than the Bosch S922AF blade
• Bi-metal construction — HSS teeth bonded to a carbon steel body for hardness and flexibility
• Curved tooth section for improved material contact and a smoother cut
• Variable 3x3 tooth geometry (20+22+24 TPI) for optimised cutting efficiency
• Thick 1.1mm body adds rigidity for straight, accurate cuts
• Fits all S-shank reciprocating saws
