To prolong tool life and get the best cut finish, several passes are recommended, #54520, diameter (D) 1-3/16, cutting Height (B) 1-5/8, Shank (D) 1/2, overall length (L) 3-1/8, type Ogee, R2 23/32, R1 7/8, flutes 2, D1 7/16, 54520 carbide Tipped Ogee vertical raised panel 7/8 radius x 1-3/16 dia x 1-5/8 x 1/2 inch Shank
