The High Speed Steel Ball Burs Size 10 (2.7mm) Round is a professional-grade rotary cutting tool designed for jewelers who require precise shaping, smooth metal removal, and long-lasting performance. Crafted from premium high-speed steel (HSS), this larger-size ball bur offers outstanding durability, delivering clean cutting action through continuous bench work and high-speed use.
The 2.7mm round head is engineered for creating larger stone seats, carving rounded recesses, shaping metal surfaces, and performing controlled material removal on a broader area. Its spherical geometry ensures accurate cutting without chatter, making it ideal for stone setting, bezel cavity shaping, prong adjusting, and sculpting curved metal features.
With spiral-cut precision flutes, this HSS ball bur provides efficient chip clearance, minimizes heat buildup, and ensures smooth cutting even under heavy use. The standard 3/32" (2.35mm) shank guarantees compatibility with all professional rotary handpieces, flex shaft machines, and micromotors used in jewelry studios.
Ideal for gold, silver, platinum, brass, and similar alloys, this bur maintains its cutting edge significantly longer than standard burs, reducing downtime and tool replacement frequency. Its robust construction makes it perfect for professional jewelers who demand consistent, clean, and controlled cutting results on larger jewelry components.
The High Speed Steel Ball Burs Size 10 (2.7mm) Round is essential for bench jewelers requiring a dependable, high-performance bur for precision shaping and advanced metalwork applications.
