Bosch PRO S937HBF Thick Metal Reciprocating Saw Blade

The Bosch PRO S937HBF is a bi-metal reciprocating saw blade engineered for cutting thick-wall metal pipes, profiles, and steel fittings, and is claimed to last up to 5x longer than the Bosch S922AF blade.

Designed for metalworkers, electricians, and renovators, the S937HBF features a hardened high-speed steel (HSS) tooth strip bonded to a flexible high carbon steel body through bi-metal welding. This construction delivers the cutting hardness needed for tough metals while maintaining the blade flexibility that resists snapping during demanding cuts.

The curved tooth geometry improves contact with the workpiece surface, producing a smoother, more controlled cut. The variable 3x3 tooth design combines differing tooth sizes, gullet depths, and spacings — with a TPI range of 10+12+14 — to optimise cutting efficiency across material thicknesses from 4mm up to 12mm.

At 1.1mm thick and 25mm wide, the blade offers added rigidity to help maintain straight tracking through the cut. It accepts a standard S-shank fitting, making it compatible with all S-shank reciprocating saws.

Features and Benefits:
• Lasts up to 5x longer than the Bosch S922AF blade for extended service life
