Air Saws

About Air Saws

Air saws, also known as pneumatic saws, are compressed air-powered cutting tools designed for fast, precise cutting through metal, plastic, fibreglass, and composite materials. Essential equipment in automotive workshops, fabrication shops, and body repair environments, these versatile tools deliver powerful reciprocating cutting action without the weight and heat generation of electric alternatives. MyToolShed.co.uk stocks a comprehensive range of air saws from trusted brands including Sealey, Draper, and Siegen, featuring full-sized reciprocating models, slim-profile variants, and compact mini air saws suitable for confined workspace applications.

Available air saws at MyToolShed.co.uk include various configurations to suit different cutting requirements, from heavy-duty body panel work to precision trimming in tight spaces. The collection encompasses complete air saw tools alongside extensive replacement blade options in multiple TPI (teeth per inch) ratings, ensuring you can match blade specification to material thickness and desired finish quality. Operating typically at 90 PSI with 4-6 CFM air consumption, these pneumatic cutting tools offer consistent power delivery, reduced operator fatigue, and excellent manoeuvrability compared to electric reciprocating saws.

• Welders – material preparation and trimming welds to specification
• Restoration Specialists – classic car, motorcycle, and vintage vehicle restoration projects
• Custom Car Builders – bespoke fabrication and modification work
• Maintenance Engineers – cutting pipework, brackets, and structural components during repairs
• Marine Engineers – fibreglass and composite material work on boat repairs
• HVAC Engineers – cutting ductwork and sheet metal installations
• DIY Enthusiasts – home workshop automotive projects and metalworking applications

Choosing The Right Air Saws

Tool Size and Configuration: Full-sized reciprocating air saws deliver maximum cutting power for general workshop use, whilst slim-profile models excel in confined automotive spaces. Mini air saws combine cutting capability with detailed work functionality for precision applications.

Air Compressor Compatibility: Verify your compressor delivers adequate CFM output (typically 4-6 CFM at 90 PSI) for continuous operation. A minimum 50-litre tank capacity ensures consistent performance without excessive pressure cycling during extended cutting sessions.

Blade Selection: MyToolShed stocks replacement blades in various TPI ratings – lower TPI (14-18) for faster cuts through thicker materials, medium TPI (24) for versatile general use, and higher TPI (32) for smooth, precise cuts in thin materials. Ensure blade availability for your chosen air saw model.

Ergonomics and Weight: Air saws are inherently lighter than 240v electric alternatives, but consider handle design and weight distribution for overhead or awkward-angle work where operator comfort directly affects cutting accuracy and control.

Safety Information

Always wear approved safety glasses or face protection when operating air saws, as cutting generates flying metal particles and debris. Disconnect the air supply before changing blades or performing maintenance. Never exceed the manufacturer's recommended 90 PSI operating pressure, as over-pressurisation risks tool failure and injury. Inspect blades regularly for damage or wear, replacing immediately if compromised. Secure workpieces properly before cutting and be aware of what lies behind your cutting line to avoid damaging hidden components, particularly critical in automotive applications. Ensure adequate ventilation when cutting materials producing harmful dust or fumes, and comply with HSE guidelines regarding noise exposure and vibration limits for professional use.

Frequently Asked Questions

What size air compressor do I need for an air saw?

Most air saws require 4-6 CFM at 90 PSI. For continuous operation, choose a compressor rated at least 25% higher than the tool's consumption, with a minimum 50-litre tank capacity for consistent performance. Smaller compressors work for occasional use provided you allow recovery time between cuts.

How do I choose the correct TPI blade rating?

Lower TPI (14-18) cuts faster through thicker materials like exhaust tubing but leaves rougher edges. Medium TPI (24) offers versatility for general body panel and sheet metal work. Higher TPI (32) provides smoother, more precise cuts ideal for thin materials where edge quality matters.

Why choose an air saw over a 240v electric reciprocating saw?

Air saws are significantly lighter, reducing operator fatigue during extended use. They generate less heat, maintain consistent power throughout operation, and present no electrical shock hazard when working around vehicle bodies or in damp environments. The slim profile of many pneumatic models also provides superior access in confined automotive spaces.
