Busch® Pointed Burs FIG 5 – 0.70mm (ISO #070) are premium-grade rotary tools designed specifically for precision jewelry work, engraving, and detailed metal shaping. Crafted from high-quality tungsten vanadium steel, these burs offer outstanding strength, resistance to wear, and prolonged cutting performance — even under frequent use in demanding environments.
With a fine 0.70mm diameter and a 42° pointed angle, these burs are ideal for creating clean, intricate cuts, carvings, and precise detailing in precious and semi-precious metals including gold, silver, platinum, palladium, and even harder alloys. Their ultra-fine pointed tips allow for access into tight areas and precision-focused applications such as stone setting, undercutting, and micro-engraving.
Each bur is precision-machined with uniform tooth spacing to deliver smooth, chatter-free cutting, ensuring a clean finish with minimal effort. These features make them highly valued by professional jewelers, engravers, stone setters, and watchmakers worldwide.
Each pack includes 6 identical burs, making them a reliable, cost-effective solution for jewelers who require consistent, repeatable results across multiple projects. The burs are compliant with ISO #070 standards, ensuring international compatibility and uniformity in dimensions and quality.
The 3/32" (2.34mm) shank size is compatible with most standard rotary tools, including flex shafts, micromotors, and Dremel-type tools. Each bur is approximately 1-3/4" (44.5mm) long.
For best results and extended bur life, it is recommended to use a suitable bur lubricant, such as Busch Lube-Stik, during operation. The maximum safe operating speed varies depending on the bur’s size — detailed guidance is provided on the product packaging.
