cutting angles: adjust the bevel from 0 to 60 degrees to tailor cuts to project requirements, enabling precise, controlled results with ease. Durable design: made from a sturdy blend of aluminium alloy and stainless steel, providing wear resistance during extended woodworking tasks. Optimized for circular saws: this guide rail is designed to improve circular saw performance, delivering precise and clean cuts across different materials. Simple installation: the design allows for straightforward setup, letting you concentrate more on your woodworking rather than assembly hassles. Use scenario 1: Cabinetmaking and shelving projects where exact bevels and joints are needed; set the angle quickly for precise faceframes, shelves, and supports. Use scenario 2: General crosscutting and bevel cuts on plywood, melamine, and hardwood; achieve clean edges and repeatable results across materials. Use scenario 3: Trim and finishing work such as baseboards and mouldings requiring straight, accurate cuts for a professional fit.
