Lâmina de serra sabre Bosch S 1122 BF, bimetal, 175 mm comprimento de trabalho, 2 mm espaçamento entre dentes, 2 unidades

Sabre saw blade Bosch S 1122 BF is a bimetal reciprocating saw blade designed for cutting metal with precision and durability. The blade provides a 175 mm working length and 2 mm tooth spacing, enabling cuts in sheet metal, pipes and profiles up to 8 mm thick. Delivered as a pack of two blades on cardboard backing, this blade is suitable for flush cutting and general metal demolition tasks when fitted to a compatible reciprocating or sabre saw.

Advantages

The bimetal construction combines high-speed steel cutting edges with a flexible alloy backing for improved wear resistance and reduced breakage. A 2 mm tooth pitch is balanced for faster cutting while maintaining a controlled finish in thin-to-moderate metal sections. The 175 mm working length gives extended reach for through-cuts and plunge cuts, and the blade geometry is optimised for flush cutting in metal applications.

Suitable for

• Cutting sheet metal and thin steel plates
• Cutting pipes and tubular metal sections
• Cutting metal profiles and channel sections
• Flush cutting and demolition work in metal

How to use

Install the blade in the reciprocating or sabre saw according to the tool manufacturer's instructions, ensuring the blade is properly seated and secured. For metal cutting, clamp the workpiece firmly, mark the cut line and use steady feed pressure without forcing the blade. Start cutting at low speed to establish the kerf, then maintain an even pace to prevent overheating. Allow the blade to cool periodically during extended cutting to prolong life.

Recommendations

Use cutting fluid or light lubrication when cutting thicker metal to reduce heat and extend blade life. Select appropriate personal protective equipment (safety glasses, gloves, hearing protection) and ensure secure workpiece clamping. Replace blades showing excessive wear, tooth damage, or frequent wandering for safer and cleaner cuts.
