Aviation Snips

About Aviation Snips

Aviation snips are specialist hand-cutting tools designed for precision cutting of sheet metal, plastic, and other thin materials up to 1.2mm thick. Originally developed for the aircraft industry, these versatile cutting tools feature a compound leverage mechanism that multiplies cutting force, making them significantly more powerful than traditional tin snips. MyToolShed.co.uk stocks professional-grade aviation snips from trusted brands including Stanley, Irwin, Bahco, DeWalt, Milwaukee, and Sealey, with options ranging from individual snips to complete three-piece sets.

Modern aviation snips are colour-coded for easy identification: red handles for left-cutting (anticlockwise curves), green handles for right-cutting (clockwise curves), and yellow handles for straight cuts. This standardised system helps tradespeople quickly select the appropriate tool for the job. Features such as spring-loaded action, ergonomic soft-grip handles, and hardened steel blades ensure these tools deliver clean, accurate cuts through aluminium, copper, mild steel, vinyl siding, and ductwork without causing distortion or leaving rough edges.

Applications

Aviation snips are essential tools across numerous trades and industries:

• HVAC Engineers – cutting and fabricating ductwork, ventilation systems, and metal housing components
• Roofers – trimming flashing, guttering, and metal roofing materials
• Sheet Metal Workers – precision cutting and fabrication of various metal products
• Plumbers – cutting copper sheet, pipe clips, and metal securing straps
• Electricians – trimming cable trunking, metal conduit, and electrical enclosures
• Motor Mechanics – cutting sheet metal during bodywork repairs and custom fabrication
• Builders and Carpenters – cutting metal studs, tracks, and general site metalwork
• DIY Enthusiasts – home improvement projects involving guttering and sheet materials

Choosing The Right Aviation Snips

Cutting Direction: Determine whether you need left-cutting (red), right-cutting (green), or straight-cutting (yellow) snips. For comprehensive versatility, consider a three-piece set from brands like Irwin, BlueSpot, or Bessey that includes all cutting types.

Material Capacity: Check the maximum material thickness the snips can handle. Standard aviation snips typically cut up to 1.2mm mild steel, whilst heavy-duty compound models can tackle thicker materials. Consider the materials you work with most frequently—stainless steel requires more robust blades than aluminium.

Handle Comfort: Look for ergonomic handles with soft-grip coating, particularly for extended cutting tasks. Quality brands incorporate cushioned grips that reduce hand fatigue and prevent blisters during prolonged use.

Leverage Type: Compound leverage aviation snips reduce cutting effort by approximately 40% compared to standard models, making them ideal for professional tradespeople working with tougher materials or performing high-volume cutting.

Safety Information

Always wear cut-resistant gloves and safety glasses when using aviation snips, as cutting creates sharp edges and metal fragments. Freshly cut metal edges are extremely sharp—deburr immediately using a file or deburring tool. Position material securely and keep hands clear of the cutting path. Store aviation snips with blade guards or in protective pouches to prevent accidental cuts. Never exceed the rated cutting capacity, as this can damage blades and compromise safety.

Frequently Asked Questions

What's the difference between aviation snips and regular tin snips?

Aviation snips feature compound leverage mechanisms that multiply cutting force, making them significantly more powerful than traditional tin snips. They also include spring-loaded action for automatic blade opening, ergonomic handles, and can cut tighter curves with greater precision and control.

Do I need all three types of aviation snips?

Professional tradespeople regularly working with sheet metal benefit from having all three types for maximum versatility. However, DIY users or those performing occasional cutting may find straight-cutting (yellow) snips meet most needs. MyToolShed.co.uk offers individual snips and complete sets to suit different requirements and budgets.

What's the maximum thickness I can cut with aviation snips?

Most standard aviation snips cut up to 1.2mm mild steel (approximately 18 gauge), though capacity varies by model and material type. Softer materials like aluminium can typically be cut at greater thicknesses. Always check the manufacturer's specifications and never exceed the rated capacity.
