Busch® Pointed Burs FIG 5, 3.50 mm (ISO #035) are premium precision tools tailored for expert jewelry work and fine metal detailing. Made from tungsten vanadium steel, these burs deliver outstanding strength, long-term durability, and high wear resistance even under rigorous use. The 3.50 mm diameter combined with a sharp, pointed tip allows for crisp, intricate shaping and carving on delicate jewelry pieces such as gold, silver, platinum, and other precious metals.
Each bur is fine‑machined with uniformly spaced cutting teeth to ensure smooth, accurate cuts—critical for detailed engraving, texturing, and surface refinement. Supplied in a pack of 6, this set offers excellent value for professional jewelers and engravers who must rely on consistent, high-quality performance. The ISO #035 standard ensures dimensional precision and consistent quality on an international scale.
These burs are designed to be compatible with most standard rotary tools using a 3/32" (2.35 mm) shank. They typically measure approximately 1‑3/4" in overall length, making them suitable for use in flex shafts, micromotors, and Dremel-style handpieces. With a 42° cutting angle, they provide an optimal balance between penetration and control. For peak efficiency and to prolong tool life, a lubricant (e.g. Busch Lube‑Stik) should be used. Safe operating speeds will depend on the bur size and material; check the packaging for RPM limits.
As part of the Busch® Pointed Burs series (available in sizes from 0.60 mm up to 5.00 mm), this 3.50 mm variant is ideal for more robust detail tasks and stands on the same high standards of German engineering and quality control.
