This router bit from the Cutting Tools category is an asset to my DIY projects. Through trial and error, I found that the precision of this bit is unmatched. It cuts clean, accurate and sharp making my woodworking and cabinetry projects effortless. The industrial and scientific design of this router bit provides durability and is built to last. The only downside I found is that it is a BIT heavy, which can make prolonged use tiring. Overall, I am beyond satisfied with this purchase and would recommend it to anyone in need of a reliable cutter bearing..
