Product Description
CMT Bowl and Tray Router Bit - 7/16" Diameter x 1/2" Cutting Height, 1/8" Radius, 1/4" Shank is a precision carbide-tipped routing bit designed for shaping smooth radiused recesses in woodworking projects. With its 2-flute hardwood-grade carbide construction and right-hand rotation, this bit excels at crafting bowls, serving trays, decorative boxes, cutting boards, and specialty craft items.
