Niqua® 82 Tool Steel Burs Long Bud

Shape deep concave hollows, smooth tapered contours, and machine transitional curves in precious metal mountings without leaving flat facets or tool chatter. Manufactured to Swiss-Made standards for NIQUA, the NIQUA® SUPER Q® Long Bud Bur "82" (Knospfräser lang) is a heavy-duty rotary milling and contouring cutter engineered for professional goldsmiths, diamond setters, sculptors, and fine metalworkers.

Featuring an elongated bud-shaped (bullet) cutting head with a gently rounded dome tip and tapered side flanks, the Series 82 bur combines end-face smoothing with broad flank milling. This profile allows artisans to access deep recesses with the domed nose while using the tall tapered body to true internal walls, clear heavy casting sprues, and blend flowing contours smoothly. Forged from premium hardened tool steel, each bur delivers clean chip evacuation and dependable edge retention in soft, ductile alloys including yellow gold, sterling silver, copper, brass, and related non-ferrous metals. Fitted with an industry-standard 2.35 mm (3/32") shank, these large long bud burs mount directly into jeweler flexible shaft handpieces, heavy-duty bench micromotors, and quick-change chuck systems. Available in substantial diameters of 6.00 mm and 8.00 mm (Art.-No. 03 243 060 and 03 243 080), each size is packaged in a bench storage box containing 6 pieces.

Why Choose NIQUA® SUPER Q® 82 Long Bud Burs

• Distinctive Long Bud (Bullet) Geometry: Combines a rounded apex with an extended tapered body, providing depth reach and continuous flank milling in deep cavities. 

• Smooth Transitional Contouring: The rounded nose eliminates sharp digging marks, enabling smooth transitional passes inside hollow signet rings, heavy bezels, and cast components. 

• Deep Swarf Evacuation Flutes: Precision-ground flutes clear metal shavings quickly outward during heavy stock removal, preventing tool loading and galling in ductile gold and silver. 

• Low-Vibration Concentric Operation: Precision-ground tool steel core minimizes radial runout, ensuring steady handpiece tracking and smooth cuts. 

• Hardened Swiss-Quality Tool Steel: Provides wear resistance, edge sharpness, and extended service life across continuous workshop use. 

• Universal 2.35 mm (3/32") Shank: Provides compatibility across standard flexible shaft systems, quick-change handpieces, and laboratory micromotors without collet adapters.
