Alligator & Tyrannosaw Saw Blades

About Alligator & Tyrannosaw Saw Blades

Alligator and Tyrannosaw saw blades are specialist cutting accessories designed for counter-oscillating power saws used in demolition, construction, and rescue operations. Unlike conventional reciprocating saw blades, these feature a unique twin-blade design where two parallel blades move in opposite directions simultaneously, gripping materials for safer, more controlled cutting with reduced kickback. This innovative design makes them particularly effective for cutting through mixed materials including timber with embedded nails, plastic pipes, and light metals.

MyToolShed.co.uk stocks replacement blades for both Alligator saws (specifically designed for Black & Decker models) and Tyrannosaw-compatible tools from various manufacturers. Available in different lengths and tooth configurations, these robust blades range from general-purpose options for construction work to specialised pruning blades for green wood and carbide-tipped versions for abrasive materials and extended service life.

Applications

Alligator and Tyrannosaw saw blades are essential tools for numerous trades and applications:

• Demolition contractors – rapid cutting through mixed materials during strip-out projects
• General builders – site work involving joists, studwork, and materials with hidden fixings
• Emergency services – vehicle extrication and rescue operations requiring reliable cutting performance
• Landscape gardeners and arborists – tree surgery, branch removal, and garden maintenance
• Plumbers – cutting plastic and copper pipework during installations and renovations
• Carpenters – quick timber cutting in renovation work where embedded nails may be present
• Fencing contractors – cutting fence posts, rails, and panel materials on-site
• Property maintenance teams – general cutting tasks across residential and commercial contracts
• DIY enthusiasts – home renovation projects and garden work

Choosing The Right Alligator & Tyrannosaw Saw Blades

Material compatibility: Select blades based on what you're cutting. General-purpose blades suit wood and plastics, whilst carbide-tipped options provide extended life when cutting through materials with embedded fixings. Pruning-specific blades prevent clogging when cutting green wood and branches.

Blade length: Available in 150mm to 240mm lengths. Choose according to your maximum cutting depth requirements, ensuring compatibility with your saw's specifications.

Tooth configuration: Lower TPI counts (6-8 teeth per inch) deliver faster, aggressive cuts ideal for demolition work. Medium TPI (8-10) offers versatility for general construction, whilst higher TPI provides smoother finishes for precision work.

Brand compatibility: Verify that blades fit your specific saw model. Black & Decker Alligator saws may require genuine or specifically designed blades, though many universal-fit options are available at MyToolShed.co.uk.

Professional versus DIY use: Tradespeople benefit from carbide-tipped blades and multi-packs for better value and on-site availability. Occasional users may find standard high-carbon steel blades adequate for intermittent projects.

Safety Information

Always disconnect the tool from the 240v power supply before changing blades. Wear appropriate safety glasses or face shields to protect against flying debris, and use hearing protection during extended operation. Cut-resistant gloves should be worn when handling blades, never whilst the tool is operating.

Inspect blades before each use for damage, cracks, or excessive wear. Replace dull blades immediately as they require excessive force and increase the risk of losing control. Before cutting, check materials for hidden hazards including electrical cables, water pipes, and structural fixings using appropriate detection equipment.

Ensure materials are properly secured before cutting and maintain a stable stance throughout operation. Store blades in protective cases to prevent accidental contact with cutting edges and to maintain sharpness.

Frequently Asked Questions

Can I use standard reciprocating saw blades in an Alligator saw?

No, Alligator and Tyrannosaw-style saws require specifically designed twin blades that work with the counter-oscillating mechanism. Standard reciprocating saw blades are single-blade designs with completely different mounting systems. Attempting to use incorrect blades could result in tool damage and serious safety hazards.

Which blade should I choose for cutting branches and garden waste?

Select pruning-specific blades designed with aggressive tooth patterns and wider gullets that prevent clogging with sap and fibrous material. These typically feature lower TPI counts (6-8) and specialised tooth geometry for efficient cutting through fresh, wet wood. Standard construction blades will struggle with green wood and quickly become clogged.

Are carbide-tipped blades worth the extra cost?

For professional tradespeople and frequent users, carbide-tipped blades offer excellent value despite higher initial costs. They maintain cutting performance significantly longer than standard steel blades, particularly when cutting materials with embedded fixings or abrasive content, reducing blade changes and overall consumable costs.
