Main applications:
Finish sanding
Sanding of transitions in spot repairs/smoothing of small surfaces
Removing paint defects and dried paint drips (preparation for polishing)
Sanding of hard-to-reach surfaces, small surfaces, joints and edges
Trimming edges and sanding smaller surfaces in furniture making

No one finishes more finely: the air-powered eccentric sander LEX 3 77/2.5, with a sole diameter of only 77 mm and weighing only 700 g, is the ideal professional tool for sanding small surfaces, e.g. when repairing or smoothing transitions. Or for sanding hard-to-reach surfaces, small surfaces, joints and edges.
Also, the LEX 3 77/2.5 is durable, long-lasting and, thanks to the smallest air consumption, ensures great cost savings – at the same time with small vibration values and low operating noise.

Very durable construction ensures a long service life, low maintenance requirements and saves costs.
A pleasant working sound, low vibration values and safe discharge of exhaust air through the compressed air hose save the user's health
The sanding pad brake reduces possible sanding errors when placing the sander and thus rework and costs
Low air consumption ensures great savings on costs

Extremely durable and long-lasting
Low-maintenance and durable motor with double-sealed bearings and high speed stiffness ensures only short downtimes and a long service life.

Three functions in one: IAS system
The IAS 3 hose system combines three functions into one hose: compressed air supply, exhaust air return and dust extraction.
Sanding dust and exhaust air are kept away from the work surface.
Thanks to the cleverly designed exhaust air return system, cold air does not escape: hands and wrists stay warm, work is more comfortable and healthier.

Very handy and comfortable
Precise control and sanding thanks to the device's Softgrip coating.
Well-balanced ergonomics also ensures easier operation.

Low air consumption
Less is more. The LEX 3 77/2.5 air consumption is the lowest of all: only approx. 270 l/min. This is about 30% less than with devices from other manufacturers – and saves money.

Highest quality of the surface
The unique sole brake reduces the rotation of the sanding pad and thus prevents the formation of sanding marks when placing it on the surface – less rework and costs.

Speed adjustment during sanding
The ergonomic position of the speed preselection allows stepless adjustment with the thumb even during sanding.

Well-readable gear marking
The sanding stroke is printed as a readable number on the top of the ergonomic safety switch. The safety switch also acts as a sensitive sanding accelerator switch.

Antistatic function
Mobile vacuum cleaners and machines against the formation of static charge when working with the antistatic function.

Vibration damping
Especially high vibration quality to ensure optimally smooth movement and the possibility of additional adjustment of the rotational speed in case of high vibration for health-saving work.

StickFix STF
Quick closing principle for attaching sanding tools – without glue and clamps – for greater economy.

Quick brake
For safe work when planing, sawing and milling.

IAS 3 SD
For direct connection of the Festool air sander to the compressed air pipe (without dust extraction).

IAS 3 light
Dust extraction, compressed air with external exhaust air management.
