Dormer P721 Ball Nosed Cone Carbide Burr 10mm 20mm 6mm

This Dormer P721 Ball Nosed Cone Carbide Burr features a 10mm diameter cut with a 20mm cut length, making it the ideal choice for precision work and detailed machining in steel and cast steel. The compact cutting dimensions offer exceptional control for intricate edge rounding, hole refinement, and fine finishing work in professional or home workshop environments. The ball-nosed cone shape is particularly effective at accessing confined spaces and tight angles where larger burrs cannot reach. Constructed with a solid carbide tip and toughened steel shank, this burr delivers consistent performance across demanding applications. The ST single cut flute style incorporates chip-breakers and medium-spaced edges to ensure efficient material removal whilst minimising clogging. With a 6mm shank diameter and 65mm overall length, this variant provides excellent manoeuvrability for detailed metalworking tasks in ferrous materials.
