The Dormer P521 Ball-Nosed Cone Carbide Burr is a high-performance cutting solution designed for precision tasks in high-temperature alloys. With its ball-nosed cone (L shape) design, this carbide burr excels at enlarging holes, rounding edges, and surface-finishing in tight, narrow angles or other hard-to-reach areas. Crafted from solid carbide and finished with a bright coating, it ensures long-lasting durability and smooth cutting performance. The AS single-cut flute style, featuring a light left-hand cross-cut, allows for efficient material removal, providing precise control and clean results. Features and Benefits • Ground finish to prevent work material from sticking to the the cutting edges • AS cut is first choice for Superalloys. It ensures high quality surface finish with fast and smooth cutting action. • Micrograin Carbide providing extreme hardness and wear resistance providing increased tool life when machining difficult materials Specifications • Diameter Cut: 3mm • Lengt
