Niqua® 8235 Set

Equip your jewelry bench with an all-in-one rotary tooling system engineered to cut stone seats, round prongs, mill flat bearing surfaces, and contour curved mountings without tool chatter. Manufactured to Swiss-German standards for NIQUA, the NIQUA® SUPER Q® "8235" Tool Steel Bur Set combines essential bur geometries in calibrated jeweler sizes.

Featuring a master selection of precision-ground burs, the 8235 set covers every critical jewelry fabrication phase from initial roughing and undercutting to stone seating and final claw doming. The collection includes foundational shapes: Ball (A), Lens (HH), Wheel (K), Inverted Cone (24), 45° Cone (NN), 30° Cone (N), 90° Cone (P), Stone-Setting Bur (Q), Cylinder (RR), Cup Bur (S), Wheel (Y), and Bud Shape (Z). Machined from premium hardened tool steel and finished primarily with precision fine cut (f) fluting, each bur delivers clean chip evacuation and low-vibration operation in ductile alloys such as yellow gold, sterling silver, copper, and brass. Fitted with universal 2.35 mm (3/32") shanks, every tool drops directly into jeweler flexible shaft handpieces, precision micromotors, and quick-change bench systems. The complete assortment is organized in a compact, clear-domed rotating bench carousel stand that protects cutting edges and keeps sizes indexed at the workstation.
