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, 700 g body weight and low compressed air consumption

The Festool LEX 3 77/2,5 is a compact compressed air eccentric sander designed for fine finishing, spot repair, blending and sanding smaller or difficult-to-reach areas. With its 77 mm sanding pad, 2.5 mm sanding stroke and extremely low tool weight, this pneumatic sander gives the user excellent control when working on transitions, edges, seams, beading and small surfaces. Built for professional paint, automotive, furniture and finishing work, the LEX 3 77/2,5 combines low vibration, pleasant operating noise and efficient compressed air use to support smoother work and a healthier working environment.

Small pad, fine finish and proper pneumatic control

The LEX 3 77/2,5 is made for surface finishing where a full-size sander is simply too large. It is ideal for spot repairs, small panels, furniture edges, blending work and polishing preparation. When used with the correct IAS 2 or IAS 3 connection system and suitable dust extraction, it becomes a clean, efficient and comfortable finishing solution for professional users.

Product highlights

Compact 77 mm sanding pad: Ideal for small areas, transitions, seams, edges and difficult-to-access surfaces.
Fine 2.5 mm sanding stroke: Designed for finishing, blending and controlled surface preparation.
Very lightweight: The 700 g body weight helps reduce fatigue during detailed sanding work.
Low vibration: High balancing quality supports smoother operation and healthier working.
Low operating noise: More pleasant to use during longer finishing and paint-preparation tasks.
Sanding pad brake: Helps reduce sanding marks when setting the machine onto the surface.
Low air consumption: Efficient compressed air use helps reduce operating costs.
IAS system operation: Requires an IAS 2 or IAS 3 connecting system for proper operation.

Extra Information

The LEX 3 77/2,5 is a compressed air sander and requires a suitable compressed air supply.
An IAS 2 or IAS 3 connecting system is required for operation.
The small 77 mm pad makes this sander especially useful for spot repair and blending work.
Use with suitable Festool StickFix abrasives for best sanding performance.
For dust-controlled work, use the correct Festool IAS hose and compatible dust extraction setup.
The machine is designed for professional finishing applications where low vibration, low noise and precise handling matter.

Pro Tips

Use the LEX 3 77/2,5 for small surface correction and blending where a larger 125 mm or 150 mm sander would be too aggressive or awkward.
Keep air pressure consistent at the recommended operating pressure for best sanding performance.
Use the correct IAS hose setup. This tool is happiest when the air supply, exhaust air and dust extraction are all working properly.
Let the abrasive do the work. Pressing too hard can reduce finish quality and shorten abrasive life.
Use progressively finer grits before polishing preparation to avoid leaving visible sanding marks.
Add the supplied cleaning and lubricating oil as required by the maintenance instructions to support long service life.

How to Use

Check that the compressed air supply is clean, suitable and set to the required operating pressure.
Connect the sander using the correct IAS 2 or IAS 3 connecting system.
Fit the required 77 mm StickFix abrasive disc to the sanding pad.
Connect suitable dust extraction if the sanding setup requires extraction.
Place the sanding pad flat on the workpiece before starting the machine.
Guide the sander evenly over the surface with light pressure and controlled movement.
Work through the required abrasive grits until the desired finish is achieved.
Stop the machine and allow the sanding pad to come to rest before lifting it away from the workpiece.
Disconnect the air supply before changing accessories, inspecting the pad or cleaning the tool.
Clean and lubricate the machine according to the Festool maintenance instructions.
