The new Magnetic Micro Square makes squaring up your table saw, band saw or any piece of equipment, effortless! The square sticks firmly to the cast iron table and allows hands free adjustment of spindles, blades and fences. It has imperial and metric graduations up to 100mm (4in) long. The base also acts as a registration ledge on work pieces to make it easier to reference. Two powerful neodymium magnets are fitted in the base.
