Down-Cut 3/4″ Plywood Dado Bit – 530-DNC720 (AstraHP Coated)

Cut Clean. Fit Tight. Last Longer. Our 3/4″ Triple Flute Down-Cut Undersized Plywood Bit is made for one job—cutting perfect dados and grooves in today’s undersized plywood. With a true 0.72″ cutting diameter, it delivers the ideal fit for 3/4″ nominal sheet goods. The down-cut flutes leave a crisp, splinter-free top edge, perfect for cabinet parts and finished surfaces. Built with a rigid 1/2″ shank for stability and precision, and finished with our AstraHP Coating, this bit stays sharper longer—giving you up to 3X the tool life of uncoated bits, even in tough materials like MDF or veneered plywood. Pair it with our 3-piece undersized plywood set for matching 1/4″, 1/2″, and 3/4″ bits to cover all your dado needs.
