Air Engravers

About Air Engravers

Air engravers are precision pneumatic tools designed for permanent marking, etching, and engraving across metals, plastics, wood, glass, and ceramics. Powered by compressed air rather than electricity, these compact tools deliver rapid vibrating action through a tungsten carbide needle, allowing tradespeople to create permanent markings with exceptional control and accuracy. Whether marking tools for identification, engraving serial numbers for asset tracking, or adding decorative details to metalwork, an air engraver provides a reliable solution for workshop and site environments.

MyToolShed.co.uk stocks quality air engravers from trusted brands like Sealey, along with essential replacement tungsten carbide engraving needles. Pneumatic air engravers offer distinct advantages over electric models including lighter weight, reduced heat generation during extended use, and consistent power delivery when connected to a suitable air compressor. The ergonomic pen-like design allows comfortable single-handed operation, ideal for detailed work requiring precision and steady control.

Applications

Air engravers are invaluable tools across numerous trades and industries where permanent marking is essential:

• Fabricators and Welders – marking part numbers, weld identifications, and project references on metal components
• Mechanics and Motor Engineers – engraving tool identification, marking engine components, and asset tracking in garages
• Construction Site Managers – marking equipment and tools with company details to prevent theft on busy sites
• Electricians – marking cable identification, panel references, and equipment labels in electrical installations
• Quality Control Inspectors – marking batch numbers, inspection dates, and compliance information on manufactured goods
• DIY Enthusiasts – personalising projects, marking valuable tools, and creative craftwork at home
• Jewellers and Engravers – decorative engraving work on precious metals and personalisation services

Choosing The Right Air Engravers

Air Compressor Compatibility: Ensure your compressor delivers the required CFM and PSI. Most air engravers operate efficiently at 90 PSI with modest air consumption (typically 2-4 CFM), making them suitable for smaller workshop compressors.

Intended Materials: Harder materials like stainless steel require robust tools with quality tungsten carbide needles, whilst softer materials like aluminium, brass, and plastics are less demanding. Models with adjustable power settings offer greater versatility across different materials.

Ergonomics: For extended use or detailed work, choose a lightweight, well-balanced model with comfortable grip design to reduce fatigue and improve accuracy.

Needle Availability: Check that replacement tungsten carbide needles are readily available. MyToolShed stocks replacement needles for continued performance, as these consumable items require periodic replacement depending on workload.

Safety Information

Always wear safety glasses to BS EN 166 standard to protect eyes from flying debris. Consider wearing a dust mask conforming to HSE guidelines when engraving metals or treated materials. Never exceed the manufacturer's recommended operating pressure, and ensure all air line connections are secure before operation. Maintain good ventilation in your workspace, particularly when engraving materials producing dust or fumes. Regularly inspect engraving needles for wear or damage, replacing them according to manufacturer guidelines. Always disconnect the air supply before changing needles or performing maintenance.

Frequently Asked Questions

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

Most air engravers require modest air consumption, typically 2-4 CFM at 90 PSI. A small to medium workshop compressor with a 24-50 litre tank is usually sufficient for continuous operation, making air engravers among the least demanding pneumatic tools.

Can I use an air engraver on glass and ceramics?

Yes, air engravers work well on glass, ceramics, and tiles. Use lower air pressure settings (60-70 PSI rather than 90 PSI) and a lighter touch to avoid cracking or chipping. Practice on scrap pieces first to develop the right technique for these delicate materials.

Do air engravers require lubrication?

Yes, add a few drops of pneumatic tool oil into the air inlet before each use, or install an inline air line lubricator for automatic delivery. Proper lubrication prevents internal wear, reduces friction, and ensures smooth operation, significantly extending your tool's working life.
