    Functions

    Saves compressed air without affecting results.

    Saves compressed air without compromising results. With a 5 mm sanding stroke, the LEX 3 125/5 compressed air eccentric sander ensures fast working progress and a high-quality sanding finish, e.g. with the coarse and intermediate sanding of flat surfaces and roundings or repair compounds in the four-step sanding process. 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 perfect for applications in the automotive sector. It is also ideal for kitchen and furniture assembly – for the intermediate sanding of wood, paint and varnish and preliminary sanding of solid surface materials.

    • 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
    • Large 5 mm sanding stroke ensures rapid working progress, a high-quality sanding finish and cost savings
    • High-quality FUSION-TEC sanding pad with MULTI-Jetstream principle ensures efficient dust extraction, minimises rework 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 highlights

    • Convenient and safe:

      Lightweight, handy, low-vibration, quiet – for fast work and a healthy working environment.

    • Systems get it done:

      Perfectly matched: Tool, sanding pad and abrasive – for gleaming results and considerable time savings.

    Product details

    LEX 3 125/5
    • 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.
