- ✓ for pre-sintered (green-state) zirconia only

If You Are Looking for…
→ coarse reduction on a flame contour (5.5x13mm): use GZH243-5C.
→ coarse reduction on a bullet contour (8.5x13mm): use GZH275-8C.
→ 2-in-1 polish on a bullet contour (10x22.5mm): use GZH507-10MF.
→ 2-in-1 polish on a point contour (7x19mm): use GZH507-7MF.
→ Everything in one box: use the ZET-USDD 9-piece set.
Handling
- Use in a standard HP lab handpiece at a comfortable bench speed; let the bur do the work on soft green-state material.
- Avoid overheating — light, intermittent pressure preserves the instrument.
- Clean zirconia dust under running water and follow your lab’s instrument-hygiene protocol.
