This product is just the cutting head without any extrusion. A Linear Cutter Head is useful when having multiple extrusions or if you end up having to replace a broken head. The idea behind this tool comes from decades of our own experience in traditional sign manufacturing where we perform long and precise cuts every day. We also wanted a tool so easy and flexible to use that anyone can handle it in just a few minutes while also being able to change the standard and affordable blades in a matter of seconds. With this tool you will experience a huge increase in your daily production and also have the satisfaction of getting perfect results every time while avoiding unnecessary waste of material.
