Makita’s T-Shank Jigsaw blades for Fast Cutting on Soft Wood & PVC are ideal for woodworkers with varied applications. For the most accurate cuts and maximal blade longevity, consider ensuring that the wood is fastened and secured, applying a firm slight forward pressure on the Jigsaw tool and allowing the blade to do the cutting. Softer wood applications enables one to use higher operating speed and orbital action without sacrificing cutting precision, while harder wood & plastic requires slower speeds and no orbital action so as to reduce the risk of jamming, excessive heat buildup and material burning while also ensuring the smoothest finishes. In general, faster, more aggressive orbital action yields a more ragged splintered finish, while slower, non-orbital action yields a finer finish.
