Festool LEX 3 77/2,5 Compressed Air Eccentric Sander

At a Glance: Compact 77 mm pneumatic eccentric sander with 2.5 mm sanding stroke, low vibration and only 270 l/min air consumption.

The Festool LEX 3 77/2,5 is a compact compressed air eccentric sander built for fine finishing, spot repairs, blending work and sanding small or awkward surfaces. With its 77 mm sanding pad, lightweight 0.70 kg body and precise 2.5 mm sanding stroke, this professional air sander is ideal for controlled sanding on edges, seams, transitions, beading and furniture components. It is robust, economical to run and designed for smooth, low-vibration operation where surface quality really matters.

Small pad, big control for professional surface finishing

The LEX 3 77/2,5 is made for detail sanding where larger machines become clumsy. It gives the user excellent handling, low noise, low vibration and the benefit of Festool’s IAS system for compressed air supply, exhaust air dissipation and dust extraction.

Product highlights

Compact 77 mm sanding pad: Perfect for small areas, transitions, seams, edges and difficult-to-access surfaces.
Fine 2.5 mm sanding stroke: Designed for finishing and controlled surface preparation.
Lightweight handling: Weighs only 0.70 kg without accessories, helping reduce fatigue during detailed sanding work.
Low air consumption: Uses only 270 l/min at rated load, helping reduce running costs.
Low vibration design: Smooth operation supports more comfortable sanding and better control.
Sanding pad brake: Helps prevent sanding marks when placing the machine onto the surface.
StickFix pad system: Allows quick and easy abrasive changes without adhesives or clamps.
IAS system compatible: Supports compressed air supply, exhaust air dissipation and dust extraction through Festool’s IAS connection system.

Extra Information

An IAS 2 or IAS 3 connecting system is required for operation.
The IAS system can combine compressed air supply, exhaust air extraction and dust extraction, depending on the setup used.
The StickFix fastening system allows compatible abrasives to be attached and removed quickly.
The sanding stroke value is clearly shown on the head of the switch for quick identification.
This machine is especially useful where a larger sander would be too aggressive or difficult to control.

Pro Tips

Use finer grit abrasives for blending, finishing and paint preparation where the final surface quality is important.
Let the sander do the work; too much pressure can reduce sanding quality and shorten abrasive life.
Use the correct Festool IAS connection system to get the full benefit of clean air supply, exhaust air dissipation and dust extraction.
Keep the sanding pad clean and replace worn pads to maintain a smooth finish.
For spot repair work, feather the edges gradually to avoid visible sanding transitions.

How to Use

Connect the sander to a suitable compressed air supply using the required Festool IAS 2 or IAS 3 connecting system.
Check that the operating pressure is set correctly before use.
Fit the correct 77 mm StickFix abrasive for the material and finish required.
Place the sanding pad flat on the surface before starting the machine.
Start the sander using the variable speed trigger and allow the pad to run smoothly.
Move the sander evenly over the work area without pressing too hard.
Overlap sanding passes slightly for an even finish.
Release the trigger and allow the pad to stop before lifting the sander away from the surface.
After use, clean the sanding pad and check the air connection and hose for dust or damage.

Features

Compressed air drive: Built for professional pneumatic sanding applications.
77 mm sanding pad diameter: Ideal for detailed sanding, spot repair and small surface finishing.
2.5 mm sanding stroke: Provides fine sanding action for finishing and blending work.
21 000 strokes per minute: Delivers fast, smooth sanding performance.
10 500 min⁻¹ eccentric motion speed: Supports efficient material removal and quality surface finishing.

Benefits

Excellent finishing control: The small pad and fine stroke make it easier to sand transitions, edges and delicate areas accurately.
Reduced rework: The sanding pad brake helps avoid unwanted scratches and sanding errors when starting or setting down the tool.
Comfortable operation: Low vibration, low noise and light weight make the tool easier to use for longer periods.
Lower running costs: Efficient air consumption helps reduce the demand on the compressed air system.
Cleaner sanding: When used with the correct IAS system and extraction setup, sanding dust and exhaust air are kept away from the work surface.
