JURA Knife-Edge Diamond Shapers for Drill Bits & Carbide Gravers
Professional-grade diamond discs, engineered for precise shaping, finishing, and polishing of drill bit tips and carbide gravers. The knife-edge profile provides full control for accurate material removal, even in tight or detailed areas, ensuring consistent geometry and optimal cutting performance.

Blue Disc (Medium Grit): Ideal for initial shaping and correction of drill bit tips or carbide graver faces.
Yellow Disc (Fine Grit): Perfect for final polishing, producing a clean, sharp cutting edge for smooth drilling or a fluid, precise graver cut.
Each disc is mounted on a tapered mandrel for enhanced support, optimal balance, and minimized vibration during rotation, ensuring smooth, stable operation at higher speeds.

JURA Tip: Start with the blue disc to shape or correct the tool, then finish with the yellow disc for a refined, precise cutting edge that improves performance and prolongs tool life.

Compatible with all standard 2.35 mm micromotor systems.
Available individually or as a complete set.
