Fein ASTS 18-26 AS jigsaw — specs & overview

The Fein ASTS 18-26 AS is an 18V cordless jigsaw designed for heavy-duty cutting tasks. It uses a brushless motor to maintain power efficiency during extended use on dense materials. This tool operates with a stroke length of 25 mm and can reach speeds up to 3000 strokes per minute.

It handles thick timber easily. Because the motor is brushless, you get more consistent performance from your battery pack compared to older brushed models. The device weighs 2.1 kg.

This weight provides enough stability for straight cuts without causing excessive arm fatigue during long work sessions. Users can adjust the speed between 700 and 3000 strokes per minute to suit different material densities. This variable speed control helps prevent splintering when you start a cut in softer woods. It uses standard T-Shank fittings for blade changes.
