Sierra sable FEIN ASAS 18-21 K AS

The FEIN ASAS 18-21 K AS is a compact cordless sabre saw designed for mobile and versatile cutting tasks. It delivers a maximum no-load speed of 3050 RPM, a 20 cm cutting length and runs on an 18 V Lithium-Ion battery, offering a balance of power and portability for work in confined or hard-to-reach spaces.

Advantages

The tool combines compact dimensions (367 mm length, 177 mm height, 78 mm width) with low vibration (8 m/s²) and moderate sound pressure (82 dB), making it comfortable for prolonged use. Battery operation removes the restriction of cables for greater mobility, while the robust motor and specification provide reliable cutting performance across a range of materials.

Suitable for

• Cutting pipes and tubing in tight spaces
• Renovation and installation work where mobility is required
• Cutting wood, plastics and non-ferrous materials in confined areas

How to use

Charge an appropriate 18 V Lithium-Ion battery compatible with FEIN before use. Fit a suitable sabre saw blade for the material to be cut and secure it according to the manufacturer's blade-change instructions. Hold the saw firmly, align the blade with the cutting line, and start the tool at no-load speed; apply steady, controlled pressure and allow the blade to do the cutting. For best results in tight or overhead positions, maintain balance and use the compact form factor to position the saw accurately.

Recommendations

Use blades rated for the target material and avoid excessive side pressure to prolong blade and tool life. Wear appropriate personal protective equipment (eye and hearing protection, gloves) and follow FEIN safety and battery-handling guidelines.
