Bahco Sandflex 18TPI Bi-Metal Hacksaw Blade 300mm

Bahco Sandflex 18TPI Blade

The Bahco Sandflex 18TPI Blade represents the industry standard for bi-metal cutting performance in heavy-duty metalworking and site fabrication. This professional-grade component utilizes a high-speed steel tooth line electron-beam welded to a flexible spring steel back. This specific construction ensures the blade remains virtually unbreakable while maintaining high cutting precision on various metal grades.

Built for the Job

Contractors and metalworkers select this 18 TPI (Teeth Per Inch) configuration for cutting solid materials and heavy-walled sections where speed and durability are required. The coarse tooth pitch excels in materials with a thickness of 6mm to 25mm, preventing the gullets from clogging while maintaining efficient chip removal. On busy job sites, the shatterproof nature of the bi-metal strip provides an essential safety margin for operators using hand frames in awkward positions or high-pressure environments.

• Cutting structural steel sections, heavy-gauge pipework, and solid metal bars on site.

• Industrial maintenance tasks involving stainless steel, cast iron, and tool steel.

• General workshop fabrication where blade longevity and heat resistance are critical.

Product Highlights

Bi-Metal Construction

The fusion of M2 high-speed steel teeth and a flexible alloy back ensures the edge stays sharp while the body resists snapping.

Safety Engineering

• Virtually unbreakable design prevents shattering during heavy use
• Flexible back absorbs impact and bending stresses without failure

Cutting Efficiency

Precision ground teeth provide a clean finish and reduce the physical effort required for manual cutting tasks.

Technical Specifications

What’s Included

• Full Box of 18TPI Bi-Metal Hacksaw Blades

On-Site & Workshop Notes

• Ensure the teeth point forward when installing the blade into a standard hand hacksaw frame.

• Maintain consistent pressure and a steady stroke rate to maximize the lifespan of the high-speed steel edge.

• Use this specific tooth count for thicker metals; for thin-walled tubing or sheet metal, consider a higher TPI variant.

• Store these replacements in a dry environment to prevent surface oxidation on the carbon steel backing.
