Niqua® 4235 Set

Streamline your bench operations with an essential rotary bur assortment engineered to mill stone seats, round prongs, cut flat bearing floors, and shape transitions cleanly without chatter. Manufactured to Swiss-German standards for NIQUA, the NIQUA® SUPER Q® "4235" Tool Steel Bur Set combines core jewelry bur profiles in medium-to-large calibrated sizes.

Targeted specifically at goldsmiths, jewelers, and model makers executing heavier fabrication, stone setting, and repair work, the 4235 set brings together 8 core profiles: Round / Ball (A), Wheel (K), 30° Cone (N), 60° Cone (O), 90° Cone (P), Stone-Setting Bur (Q), Cylinder (RR), and Cup Bur (S). Machined from premium hardened tool steel and ground primarily with precision fine cut (f) fluting, each bur delivers clean chip evacuation and low-vibration operation across soft precious metals like yellow gold and sterling silver, as well as copper, brass, and related non-ferrous alloys. Fitted with universal 2.35 mm (3/32") shanks, every tool seats directly into jeweler flex shaft handpieces, precision bench micromotors, and quick-change bench systems. The assortment is housed in a compact benchtop rotary carousel stand with a clear protective dome cover that safeguards cutting teeth from dust and bench filings.
