Craftro HP 2.35mm Dental Lab Sintered Diamond Discs Fine 22*0.2mm 1/pk

Material High‑strength steel substrate with sintered industrial diamond abrasive layer; fitted with standard 2.35 mm HP metal shank core.

Max Recommended Speed 20,000 RPM Maximum Working RPM range: 8,000‑12,000 RPM for Fine grit

Key Features

1. Sintered diamond cutting disc, 22 mm diameter, 0.2 mm thickness, compatible with standard 2.35 mm HP dental lab straight handpieces.
2. Advanced sintered diamond bonding technology firmly locks diamond grains, offering outstanding wear resistance and longer service life compared to electroplated diamond discs.
3. Fine‑grit formulation delivers neat, burr‑free cutting edges, effectively lowers chipping risk for brittle porcelain and ceramic materials. Autoclavable up to 135 °C for repeated laboratory reuse.
4. Compact 22 mm outer diameter grants easy access to tight, confined spaces for precise sectioning and separation tasks.
5. High‑rigidity steel base reduces operational wobble; evenly distributed sintered diamond grains maintain consistent cutting performance.
6. Ultra‑thin 0.2 mm kerf produces narrow cutting gaps, minimizes material loss for fine‑detail separation and trimming operations.

Application Range ✅ Recommended for:

• Fine sectioning & separation of precious and non‑precious metals, dental alloys
• Precision cutting and trimming of porcelain, monolithic zirconia and all‑ceramic restorations
• Fine trimming for crowns, bridges, metal copings and partial denture frameworks
• Precision lab cutting for cast dental prosthetic components

❌ Not for:

• Direct intra‑oral clinical use on natural teeth
• Composite resin materials

Operating Remarks

• Do not exceed maximum 20,000 RPM.
• Apply light continuous cutting pressure; avoid heavy side‑loading to prevent disc cracking or fracture.
• For dental laboratory use only.
