Puukkosahanterä Bosch S 922 HF bimetal 15 cm puulle metallille

The Bosch S 922 HF Bimetal sabre saw blade, 15 cm length, is designed for cutting a mix of materials including wood with nails, profiles and sheet metal. Its bimetal construction balances flexibility and durability, allowing reliable performance in renovation and demolition tasks. The blade's 2.5 mm tooth spacing and 15 cm working length provide controlled cuts through materials up to 100 mm thick, offering a practical solution where varied material composition is present.

Advantages

The bimetal design combines high-speed steel teeth welded to a flexible backing, increasing resistance to wear and reducing breakage during demanding cuts. A 2.5 mm tooth pitch delivers a compromise between cutting speed and finish quality suitable for mixed-material applications. At 15 cm length the blade reaches deeper cuts than short blades while remaining compatible with standard sabre saw holders, simplifying replacement and use on job sites.

Suitable for

• Cutting wooden beams and boards containing embedded nails
• Trimming metal profiles and sheet metal
• Demolition where mixed materials (wood and metal) must be removed
• Renovation tasks requiring a durable, versatile blade

Key specifications

• Blade length: 150 mm
• Material: bimetal construction (HSS teeth on flexible steel backing)
• Tooth spacing: 2.5 mm
• Maximum recommended cutting thickness: up to 100 mm depending on material
• Application: wood with nails, profiles, sheet metal

How to use

Install the blade into a compatible sabre or reciprocating saw according to the saw manufacturer's instructions and ensure the blade is securely locked before operation. Select an appropriate cutting speed and apply steady feed force; avoid forcing the blade to minimize bending or premature wear. For cutting mixtures of wood and metal, start with a moderate speed to establish the cut, then adjust speed to maintain control and reduce vibration. Wear appropriate personal protective equipment and secure the workpiece before cutting.

Recommendations

For best results when cutting through wood containing nails or thin metal sheets, use consistent, moderate feed pressure and allow the bimetal teeth to do the cutting. Replace the blade if you notice excessive wear, tooth damage, or a decline in cutting performance to maintain safety and cut quality.
