Bahco 3940-150-14-ST-2P Hacksaw Blade 150mm 14TPI

The Bahco 3940-150-14-ST-2P hacksaw blade is a professional-grade tool engineered for precision and durability in metalworking tasks. This set includes two 150mm blades featuring a 14TPI tooth configuration, specifically designed to provide clean and accurate cuts across a variety of metal materials. Built with advanced bi-metal technology, these blades offer a balance of flexibility and strength, making them a reliable choice for both demanding industrial applications and detailed DIY projects.

Advantages

These blades utilize a high-performance Sandflex bi-metal construction that combines a spring steel back with HSS toothing containing 8% cobalt. This composition ensures extreme durability and resistance to wear, significantly extending the service life of the blade compared to standard alternatives. The precision-ground teeth are designed for aggressive yet controlled cutting, while the inherent flexibility of the material prevents snapping under pressure, ensuring safety and efficiency during operation.

Suitable for

• Cutting various types of metal
• Professional metalworking and fabrication
• DIY home improvement and repair tasks
• Straight and narrow cutting applications

This blade may not be suitable for cutting extremely hardened alloys or materials significantly thicker than the blade's capacity. It is also not intended for use on masonry, wood, or soft plastics, as the tooth geometry is specifically optimized for metal performance.

Key specifications

• Length: 150 mm
• Thickness: 0.9 mm
• Tooth configuration: 14 TPI
• Material: Bi-metal with 8% Cobalt HSS toothing
• Blade shape: Standard (ST) with slope shaped nose
• Quantity: 2 blades per pack

To use the blade, ensure it is securely installed in a compatible hacksaw frame with the teeth pointing forward. Apply consistent, moderate pressure during the cutting stroke and lift the blade slightly on the return stroke to prevent premature dulling of the teeth. Always ensure the workpiece is firmly clamped to avoid vibration and ensure a straight cut.

What to consider before purchase

• Verify the compatibility of the 150mm length with your existing hacksaw frame
• Ensure the 14TPI tooth count is appropriate for the thickness of the metal you intend to cut
• Confirm the material type is suitable for bi-metal blades

For optimal performance and longevity, maintain a steady cutting speed and use a light cutting oil when working with harder metals to reduce friction and heat buildup.
