Upgrade your workshop with a high-quality pneumatic air file — engineered for precision surface finishing, deburring, shaping and material removal in metalworking, die casting, automotive, fabrication and DIY projects. Powered by compressed air, an air file delivers consistent power, smooth filing action and excellent control compared with manual files or grinders.
An air file (also called a pneumatic file) is a compressed-air powered tool that oscillates a file blade back and forth at high speed for efficient material removal. It’s ideal for:
Deburring metal edges
Smoothing welds
Shaping aluminium, steel, wood & plastics
Precision finishing in tight spots
Compared to hand filing, an air file significantly reduces effort and speeds up finishing tasks while maintaining better control and accuracy.
Powerful & consistent performance: Efficient filing action without hand fatigue.
Precision work: Great for detailed finishing on metal and wood.
Versatile: Suitable for fabrication shops, automotive bodywork, engineering and carpentry.
Ergonomic & compact: Easy to use in tight spaces.
Gison Air File GP‑948 – Versatile mid-range pneumatic air file with strong performance for workshop tasks.
Q1: What exactly does an air file do?
An air file uses compressed air to drive a reciprocating file blade. It’s used for precision finishing, deburring and material shaping — removing metal or wood more efficiently than manual files.
Q2: What materials can I work on with a pneumatic air file?
Air files work well on steel, aluminium, wood, plastics and composites for surface finishing, smoothing welds and deburring edges.
Q3: Do I need a specific compressor for an air file?
A standard workshop compressor that delivers around 90 psi with a 1/4″ air inlet is suitable for most air files, just like other pneumatic air tools.
Q4: How do I change the file blade?
File blades are usually mounted on a 5 mm shank with a quick-change holder — different profiles (round, half-round, triangular) let you tackle varied shapes.
Q5: What’s the difference between an air file and a die grinder?
Pneumatic air files are tailored for controlled linear filing motion with file blades. Die grinders spin burrs or discs for grinding — useful but less precise for filing or finish work.
