Pro-Tip: Due to the large 1-inch diameter of this bit, always ensure your router is securely mounted when using a table. For the best finish in hardwood, make the cut in multiple shallow passes rather than one single deep plunge; this reduces strain on the motor and eliminates the risk of burning the wood at the bottom of the radius.
