توضیح
High quality aluminum (drill guide) and die steel(bushing),high hardness and strength,good wear-resistant and durable to use. So Fast, So Easy, So Accurate. The arms of the jig are an always-reliable parallelogram that never fails to find dead center. Simply align the precision-machined notch on the jig’s center bar with the dowel location mark on your board, hold the jig and drill. Slide the jig to the next location, align, hold and drill. No need to clamp our jig or tighten knobs or handles as so many doweling jigs require.
