Made in the USA, these hand-cut, high speed steel burs last longer than standard jeweler's burs and offer exceptional cutting efficiency.

Inverted Cone Burs feature a tapered, cone-shaped cutting head designed for creating recesses, undercuts, grooves, and detailed shapes in metal. Available in a range of sizes, these versatile burs are suitable for jewellery making, engraving, and general metalworking. Mandrel shank size is 3/32" to fit in most machines.
