Reciprocating saw blade Bosch S 922 HF for metal, sheet metal, and wood with nails, 2.5 mm tooth spacing

Bosch S 922 HF is a reciprocating saw blade engineered for mixed-material demolition and renovation work. Made from bi-metal (BIM) and featuring a side-set milled tooth design with 2.5 mm tooth spacing (approx. 10 TPI), this 150 mm long, 0.9 mm thick blade is intended to cut wood with nails, pallets, sheet metal, pipes and aluminium profiles. The blade is compatible with standard reciprocating saws that accept S-shank or similar quick-change blades and is optimized for reliable cutting performance when encountering abrasive or reinforced materials.

Advantages

The bi-metal construction combines flexibility and wear resistance to extend blade life under heavy use. Milled, side-set teeth provide aggressive cutting action across both metallic and wooden substrates, while the 2.5 mm tooth spacing balances fast cutting speed with durability when hitting nails or fibrous material. The slim 0.9 mm thickness reduces binding and allows faster reciprocating motion, and the 150 mm overall length is convenient for typical renovation and demolition tasks.

Suitable for

• Cutting wood containing nails and other embedded fasteners (up to 100 mm)
• Demolition of pallets and wooden structures (up to 100 mm)
• Cutting sheet metal, pipes and aluminium profiles (3–12 mm)
• Mixed-material renovation and dismantling tasks

Key specifications

• Material: bi-metal (BIM) for improved durability
• Tooth design: side-set, milled teeth for aggressive cutting
• Tooth spacing: 2.5 mm (approx. 10 TPI)
• Total length: 150 mm
• Thickness: 0.9 mm
• Type: S 922 HF, suited for mixed material cutting

How to use

Select a compatible reciprocating saw and securely fit the Bosch S 922 HF blade according to the tool manufacturer's instructions. Start cutting at moderate speed, applying steady forward pressure; allow the blade teeth to do the cutting rather than forcing the tool. For cuts through wood containing nails or through thin metal, maintain a consistent reciprocating motion and avoid excessive lateral bending of the blade to prevent premature wear or breakage. After heavy or continuous use, inspect the blade for wear or damage and replace if teeth are worn or the blade is deformed.

Usage recommendations

Use personal protective equipment (eye protection, gloves and hearing protection) and clamp or support the workpiece to reduce vibration. For best life and cutting quality, match cutting speed to the material: medium speed for mixed materials and lower speed with higher pressure when cutting thicker metal. Replace the blade when cutting efficiency decreases or when damage is visible.
