As an industrial worker that deals with cutting tools I had the opportunity to test this V Groove router bit on aluminum composite. As my tests showed, the Amana bit surpassed my expectations in precision and speed... It has a LONG lifespan with a low level of wear and tear. Though the price point may be a bit steep, the high-quality output it produces justifies the investment. Overall, i highly recommend this product for anyone in the market for cutting aluminum composite..
