Using this cutting tool our team found that it delivers unparalleled perfection and precision to our industrial and scientific cutting process. The smooth spiral design ensures a clean and accurate cut every time, without any binding, kickback or burning of the wood .With its durable carbide construction, this router bit is also built to last and withstand the rigors of heavy-duty use. The only minor drawback we noticed was that it tends to leave small waste shavings, but that`s hardly a deal-breaker. Overall, this 2 inch spiral cutting tool is a must-have addition to any cutting tools collection..
