Functions

Saves compressed air without affecting results.

Saves compressed air without compromising results. With a 3 mm sanding stroke, the LEX 3 125/3 compressed air eccentric sander creates a high-quality sanding finish, e.g. with the final sanding of filler in the four-step sanding process. With a 125 mm pad diameter it is also suitable for the fine and final sanding of roundings and for sanding blending zones. Weighing just 1 kg, with minimal vibration values, comfortably low noise levels, a robust and durable motor as well as extremely low compressed air consumption, it is ideal for the automotive sector as well as for kitchen and furniture assembly.

Low compressed air consumption ensures high cost savings
Low vibration levels and a pleasant operating noise protect the user's health
Extremely sturdy design ensures a long service life, minimal servicing requirements and high cost savings
Simplifies permanent dust extraction, guarantees the best working results and protects the user's health when combined with the IAS 3 light hose
High-quality FUSION-TEC sanding pad with MULTI-Jetstream principle ensures efficient dust extraction, minimises rework and saves on costs
Fine 3 mm sanding stroke produces a very high-quality sanding finish and saves on costs
Sanding pad brake reduces sanding errors when setting down the machine, thereby avoiding rework and additional costs
Note: an IAS 2/IAS 3 connecting system is required for operation

Product details

LEX 3 125/3

Extremely robust and durable

The low-maintenance and robust motor with double-sealed bearings and high speed rigidity minimises downtimes and guarantees a long service life.
Three functions in one: The IAS system

The IAS three-hose system combines three functions in a single hose: Compressed air supply, exhaust air extraction and dust extraction. Sanding dust and exhaust air are kept away from the work surface. Thanks to an intelligently designed exhaust air extraction system, no cold air escapes: Hands and wrists stay warm, work is more comfortable and better for health.
Designed to fit your hand

Accurate guidance and precise sanding thanks to SoftGrip coating on the device. The well-balanced ergonomics also ensure effortless work.
Minimal compressed air consumption

Less is more. The LEX 3 125 has the lowest compressed air consumption of them all: Just 290 l/min. That's approx. 30% less than devices from other manufacturers – which saves a lot of money.

Maximum surface quality

The unique sanding pad brake prevents the sanding pad from turning upwards and prevents the surface being scratched during sanding, thereby minimising both reworking and costs.
Pad hardnesses for every application

Hard, soft, ultra-soft. Festool offers sanding pads with three different degrees of hardness for work that is optimally adapted to the material and surface.
Speed adjustment during sanding

The ergonomic position of the speed pre-selection enables infinite adjustment with the thumb, even during sanding.
Clearly visible stroke indicator

The sanding stroke is printed on the head of the ergonomic dead-man switch as a clearly legible number. The dead-man switch is also used as a variable speed trigger for controlled sanding.
