The High Speed Steel Bur – Size 19 (4.7 mm) Inverted Cone is a precision-engineered cutting tool designed for jewelers, metalworkers, engravers, and craft professionals who require efficiency, accuracy, and durability in every cut. Crafted from premium High Speed Steel (HSS), this bur maintains exceptional sharpness even during long, high-speed operations, making it ideal for demanding professional use.

The inverted cone shape allows for smooth undercutting, precise engraving, shaping, and controlled material removal. Its broader 4.7 mm head gives enhanced surface coverage, enabling you to carve and contour metal, wood, stone, and plastic with consistent results.

With a 3/32" shank, it fits perfectly into flex-shaft tools, rotary handpieces, and micromotors. Whether you are refining bezels, cleaning castings, shaping wax models, or adding decorative textures, this Size 19 inverted cone bur delivers consistent, reliable performance.

Because it is made from high-speed steel, it withstands heat buildup and resists wear far better than standard burs. This results in longer life, reduced tool replacement costs, and a smoother finish on your workpiece.
