Description: The wheel marking gauge is an indispensable tool when marking precision joints. It can also be used as a depth gauge. Two types of cutters meet your different needs: one with a bearing provides a smoother cut and is suitable for soft woods, while the other with a locking mechanism is suitable for hard woods. It allows you to easily cut through wood fibers and make perfect cut marks. Two adjustment steps – micro-adjustment and coarse adjustment – make adjustments more detailed and precise. A knurled adjustment knob and shaft allow for quicker and easier adjustments. The 20 cm diameter precision-ground steel shaft, graduated in 1 mm increments for easy reference, ensures accurate adjustments. The 3.9 cm diameter solid brass face can slide against the edge of the workpiece for smooth marking with or against the grain. The cutter retracts into the gauge's face for protection when not in use and for easy vertical storage.
