The Fein ASAS 18-21 K AS 71330161000 is a compact and versatile 18V cordless reciprocating saw designed for fast, controlled cutting across a wide range of materials. Its compact construction and reduced vibration make it particularly suitable for mobile work, renovation, installation, maintenance and cutting in hard-to-reach areas.
Powered by a high-performance DC motor, the saw provides a variable stroke rate of up to 3,050 strokes per minute with a 21mm stroke length, allowing efficient cutting while giving the operator control over the cutting speed. The variable-speed throttle is useful when working with different materials and when greater control is required at the start of a cut.
The SDS blade-changing system enables rapid, tool-free saw blade replacement, helping reduce downtime during demanding jobs. The integrated LED work light illuminates the cutting area, while the ergonomic design and soft-grip handle help provide comfortable handling during extended use.
The ASAS 18-21 K AS is compatible with 18V AMPShare ProCORE batteries and chargers and can also be used with compatible 18V Bosch Professional cordless batteries. FEIN's AMPShare platform, together with COOLPACK 2.0 and Electronic Cell Protection (ECP), is designed to provide improved battery performance and protection.
The saw delivers a maximum cutting capacity of 200mm in wood and 100mm in metal profiles and pipes, making it suitable for a broad range of construction, workshop and maintenance applications.
