The Proxxon Tungsten Vanadium Cutters (No. 28723) are a 2-pack of rounded cone profile rotary cutters in tungsten vanadium steel for Proxxon Micromot tools, supplied in two sizes: ×4mm (5/32") and ×6mm (15/64"). Available with 2.35mm or 3.0mm shanks. The rounded cone profile — a tapered cone with a softened, rounded tip rather than a sharp point — is ideal for chamfering, angled surface shaping, and V-groove work where a sharp taper would be too aggressive or leave a pointed mark at the base of the cut. The two included sizes allow the smaller ×4mm cutter to be used for fine detail and tight areas, and the larger ×6mm for broader chamfers and angled surfaces. Head and shaft are machined from a single blank for maximum stability and concentricity.
