Hacksaw Blades

About Hacksaw Blades

Hacksaw blades are essential cutting tools for tradespeople and DIY enthusiasts working with metal, plastic, and other hard materials. Available in various tooth configurations, lengths, and materials, these blades deliver precision cuts across countless applications from plumbing and electrical work to fabrication and general maintenance. MyToolShed.co.uk stocks a comprehensive range including bi-metal blades for durability, high-speed steel (HSS) options for industrial use, and flexible carbon steel blades for general purpose cutting.

Our selection features standard 300mm hacksaw blades for full-size frames and junior hacksaw blades for detailed work in confined spaces. With trusted brands like Bahco, Irwin, Stanley, DeWalt, and Draper Expert, you'll find professional-quality blades with TPI (teeth per inch) configurations from 14 to 32, ensuring optimal performance whether cutting thick steel sections or thin-walled tubing. Premium bi-metal construction offers shatter-resistant performance and extended blade life that professional contractors depend on daily.

Applications

Hacksaw blades are indispensable across numerous trades and industries:

• Plumbers and heating engineers – cutting copper pipe, steel tube, and plastic waste systems
• Electricians – trimming conduit, trunking, and cable tray installations
• Mechanical engineers and fitters – precision cutting of metal bar, rod, and plate materials
• Motor mechanics – exhaust work, bracket fabrication, and component modification
• Maintenance engineers – general metalwork repairs and fabrication tasks
• Fabricators and welders – preparing materials for welding and assembly
• General builders – cutting metal fixings, brackets, and building materials
• DIY enthusiasts – home improvement and workshop projects

Choosing The Right Hacksaw Blades

Material and TPI Selection: Match blade tooth count to your workpiece. Lower TPI (14-18) suits thick steel sections and faster material removal, whilst higher TPI (24-32) delivers smoother cuts in thin sheet metal, tube, or conduit. Ensure at least three teeth contact the material to prevent tooth stripping.

Blade Construction: Bi-metal blades from Bahco, Irwin, or Draper Expert offer superior durability and flexibility for professional use, combining high-speed steel cutting edges with flexible spring steel backing. These resist shattering and maintain sharpness far longer than standard carbon steel alternatives. For light-duty work, economical carbon steel options provide adequate performance.

Blade Length: Standard hacksaws accept 300mm blades, whilst junior hacksaws require shorter blades (typically 150mm). Verify your frame's compatibility before purchasing. MyToolShed.co.uk stocks both sizes across multiple TPI configurations.

Application Intensity: Daily professional use demands premium bi-metal blades that withstand rigorous site conditions. Occasional DIY users may find excellent value in mid-range options from Faithfull or Sealey. Consider multi-packs with varied TPI if you regularly work with different materials.

Safety Information

Always wear safety glasses to protect against metal chips and work gloves to prevent injuries from sharp edges. Securely clamp workpieces in a vice before cutting—never attempt to cut hand-held materials. Inspect blades for damage before use and dispose of cracked or broken blades immediately by wrapping in thick paper marked as sharp waste.

Install blades with teeth pointing forward and ensure proper tension—loose blades twist and break whilst over-tightened blades may snap. Use smooth, steady strokes without excessive pressure. Allow freshly cut metal to cool before handling and deburr sharp edges before further work. Follow HSE guidelines for manual handling during extended cutting operations.

Frequently Asked Questions

What TPI hacksaw blade should I use for steel tube?
A 24 TPI blade provides the best balance for steel tube and pipe, ensuring at least three teeth contact the tube wall for clean cuts without tooth damage. For very thin-walled tube under 2mm, consider 32 TPI to prevent snagging.

How long should a quality hacksaw blade last?
Professional bi-metal blades from Bahco or Irwin typically deliver 30-50 cuts or more in mild steel, depending on material thickness and technique. Proper tension, appropriate cutting speed, and occasional lubrication significantly extend blade life. Replace when cutting becomes noticeably slower or requires excessive pressure.

What's the difference between standard and bi-metal hacksaw blades?
Standard carbon steel blades are economical but brittle and dull quickly. Bi-metal blades feature high-speed steel cutting teeth welded to flexible spring steel backing, combining superior cutting performance with shatter resistance. Whilst initially more expensive, bi-metal options last significantly longer, making them more cost-effective for regular professional use.
