1/4"Shank 3/8CD 3/8CL 9degree for Incra. The beautifully crafted dovetail joint is a classic that appeals to both professionals and novices alike. Admired for its attractiveness in exposed joint projects, the dovetail is remarkably strong and functional. CMT Dovetail bits are available in 26 different sizes including the new 8°-7/16 diameter so you can stretch your creativity to its furthest. See the illustrations on the next page for dovetail joinery possibilities. CMT Dovetail bits are designed to fit all popular jigs including Leigh, Keller, JoinTECH and Omnijig systems. You are sure to find the bit you are looking for in our vast selection of cutting sizes and angles. Check the overall length of the bit before placing an order to be sure you get the size you need - CMT makes bits specifically to fit on jigs and routers that require a longer shank length. Note: Pre-cut your dovetails with a straight bit to reduce bit breakage. Use a diameter slightly less than the small diameter at the neck of the dovetail bit. This will also improve chip removal and safety.
