Description
The ATTRITOR GZH pre-sinter Zirconia bur set is the laboratory's complete green-state shaping kit — nine HP-mounted instruments that take milled or hand-built Zirconia from rough green-state to a smooth, sinter-ready surface before the furnace locks in the shade and strength.
- ✓ Nine-piece set — coarse finishing burs plus medium-and-fine 2-in-1 polishers
- ✓ Pigment-free body — no color contamination before sintering
- ✓ Standard HP lab shank (2.35 mm) — fits the handpiece you already run
- ✓ Built for pre-sintered (green-state) Zirconia, the soft, forgiving stage
Why You’ll Love It
✦ One kit, every contour — no hunting for the right shape mid-case.
✦ Pigment-free across the set — the restoration shade is never contaminated before firing.
✦ Drops into your HP handpiece — standard 2.35 mm shank.
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.
→ Coarse reduction on a wheel contour (15x3.4mm): use GZH040-15C.
→ 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.
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.
