The Carmex Carbide Tiny Tool is a compact, solid carbide bar engineered for deep face grooving. Built for machinists, engineers, and hobbyists alike, it delivers precise, reliable grooves in tight spaces. It features a 15 mm minimum diameter, a 3 mm groove width, and a 27 mm groove depth, making it ideal for demanding deep-groove applications where standard tools struggle.
