Craftro HP 2.35mm Dental Lab Sintered Diamond Discs Medium 22*0.3mm 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: 10,000‑14,000 RPM for Medium grit

Key Features

1. Sintered diamond cutting disc, 22 mm diameter, 0.3 mm thickness, compatible with standard 2.35 mm HP dental lab straight handpieces.
2. Sintered diamond bonding technology provides strong abrasive retention, high cutting stability and far longer service life than electroplated diamond discs.
3. Medium‑grit cutting surface balances cutting speed and edge quality; delivers clean cuts with reduced chipping on hard brittle materials. Autoclavable up to 135 °C for repeated lab use.
4. Compact 22 mm outer diameter enables access to confined working areas for separating and sectioning prosthetic workpieces.
5. Rigid yet moderately flexible steel base minimizes wobble during operation; consistent diamond distribution maintains stable cutting performance.
6. 0.3 mm thin‑kerf design creates narrow cutting gaps, reduces material wastage during sectioning and separating procedures.

Application Range ✅ Recommended for:

• Sectioning & separating precious and non‑precious metals, dental alloys
• Cutting and trimming porcelain, monolithic zirconia and all‑ceramic restorations
• Cutting crowns, bridges, metal copings and partial denture frameworks
• Lab separation work 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.
• Use light continuous cutting pressure; avoid heavy side pressure to prevent disc cracking.
• For dental laboratory use only.
