I recently purchased the CMT PNL 003 Panalign Strips for my team`s router bits and they have been a game-changer.Using this product, our team found that our router bits aligned perfectly making our cuts more precise and significantly reducing the amount of waste. The strips are easy to use and have saved us a lot of time. The only con we have experienced is that the strips can be quite thin and delicate, requiring careful handling to ensure they do not tear or fold. Overall, we highly recommend this product to anyone in need of alignment assistance for their router bits..
