Sandflex Hacksaw Blade

Premium Bi-Metal Hacksaw Blade

The Sandflex Hacksaw Blade is a professional-grade bi-metal cutting blade designed for superior performance and extended blade life. Manufactured by Bahco (the Sandflex brand), these hacksaw blades feature a unique combination of high-speed steel teeth and a flexible spring steel backing, delivering exceptional cutting performance on metal, plastic, and other materials.

Key Features

• Bi-metal construction – High-speed steel (HSS) teeth welded to flexible spring steel backing
• Superior durability – Lasts up to 10 times longer than standard carbon steel blades
• Shatter-resistant – Flexible backing prevents blade breakage under stress
• Sharp, precision-ground teeth – Efficient cutting with minimal effort
• Universal fit – Standard 12-inch (300mm) length fits most hacksaws
• Multiple TPI options – Available in various teeth-per-inch configurations for different materials
• Heat and wear resistant – HSS teeth maintain sharpness even under high friction
• Professional quality – Trusted by tradespeople worldwide

Technical Specifications

• Length: 12 inches (300mm) standard
• Construction: Bi-metal (HSS teeth + spring steel back)
• Tooth Material: High-speed steel (HSS)

TPI Selection Guide

• 18 TPI – Coarse teeth for soft metals (aluminum, brass, copper), thick materials, fast cutting
• 24 TPI – Medium teeth for general-purpose cutting, most common choice for steel and iron
• 32 TPI – Fine teeth for thin materials, hard metals (stainless steel), precise cuts, tubing

Applications

Perfect for cutting steel, stainless steel, aluminum, brass, copper, iron, plastic pipes, conduit, threaded rod, angle iron, flat bar, tubing, and general metal fabrication. Suitable for automotive repair, plumbing work, electrical installations, HVAC work, metalworking, maintenance, and construction applications.

Why Choose Sandflex?

Sandflex is Bahco's premium hacksaw blade brand, renowned worldwide for quality and performance. The bi-metal construction combines the best properties of two different steels: hard, wear-resistant HSS teeth that stay sharp, and a flexible spring steel backing that resists breaking. This combination delivers exceptional blade life and cutting efficiency, making Sandflex blades the professional's choice.

Advantages of Bi-Metal Blades

Compared to standard carbon steel blades, bi-metal Sandflex blades offer:

• 10x longer blade life
• Resistance to breakage and shattering
• Ability to cut harder materials
• Consistent cutting performance throughout blade life
• Better value despite higher initial cost

Usage Tips

Select the appropriate TPI for your material (at least 3 teeth in contact with the material at all times). Install blade with teeth pointing forward (away from handle). Apply light, steady pressure – let the blade do the work. Use the full length of the blade with smooth, even strokes. For best results, use cutting fluid on hard metals. Replace blade when cutting becomes slow or difficult.

Material Cutting Guide

• Soft metals (aluminum, brass, copper) – 18 TPI, moderate speed
• Mild steel, iron – 24 TPI, steady pressure
• Stainless steel, hard metals – 32 TPI, slow speed, cutting fluid recommended
• Thin tubing, sheet metal – 32 TPI to prevent tooth snagging
• Plastic pipes – 18-24 TPI, slow speed to prevent melting

Professional Quality: Sandflex blades are manufactured by Bahco, a Swedish company with over 130 years of tool-making expertise. Each blade undergoes rigorous quality control to ensure consistent performance and reliability.

Workshop Essential: Keep a selection of Sandflex blades in different TPI ratings for complete cutting versatility. The superior blade life means fewer blade changes and better productivity.

Ideal For: Professional metalworkers, plumbers, electricians, HVAC technicians, automotive mechanics, maintenance workers, fabricators, and serious DIY enthusiasts who demand the best cutting performance.

Safety Instructions: Always wear safety glasses when cutting. Ensure material is securely clamped. Keep hands clear of cutting path. Install blade correctly with teeth pointing forward. Do not apply excessive pressure. Replace worn or damaged blades immediately.

Storage: Store blades in original packaging or blade holder to protect teeth. Keep in a dry location to prevent rust. Avoid dropping or bending blades.
