The functional KREG tool is a lightweight and compact device designed for making precise crosscuts in plywood, particleboard, wood, and other similar materials. The guide rail works with a circular saw and allows for accurate 45° and 90° crosscuts in materials up to 8 inches wide. Despite its sturdy design, the guide rail is lightweight, making it easy to mount and transport. It is fully compatible with various circular saws, regardless of blade positioning. To ensure stability during use, special GripMax pads prevent the guide from slipping. Additionally, extendable cut line indicators are included for added convenience.
