I decided to try this particular brand and bits for our renovation business when we were cutting rafter tails for custom pergolas. For our project shown, we cut 36 rafter tails from 2" x 8" treated lumber. The other flushing nozzles we have used are no match for this nozzle. Cut through the end grain like butter. I look forward to testing this manufacturer's 20 point and other bits. Highly recommended!
