Dental Plaster Cutting Disc is dedicated heavy-duty cutting tool exclusively manufactured for dental lab gypsum plaster model processing. Constructed with rigid stiff steel substrate and bonded premium natural diamond particles, it enables smooth, vibration-free plaster separation and contour trimming without crumbling model edges.

All variants adopt uniform fine 50μm diamond grit for balanced cutting speed and ultra-smooth finished plaster surfaces. Four standard dimension sizes cover full lab workflow demands:

1. Large lab bench grinder size:

• D853520: 85mm * 0.35mm * bore 20mm, perforated vented steel body for fast heat dissipation
• D903020: 90mm * 0.30mm * bore 20mm, solid stiff steel plate for maximum rigidity during heavy plaster bulk cutting

2. Small handpiece compact size:

• D452518: 45mm * 0.25mm * bore 1.8mm, fan-shaped vent structure for low-speed handpiece operation
• D352518: 35mm * 0.25mm * bore 1.8mm, mini compact design for delicate small plaster model fine trimming

Vented/perforated body designs effectively expel plaster dust and reduce thermal buildup to prevent plaster cracking during continuous cutting. Precision laser-cut steel blank ensures perfect concentricity to eliminate shaking at high rotating speeds. OEM laser marking and customized mixed-size lab kits are available for global dental lab suppliers.

• Rigid stiff steel base maintains flat shape under heavy plaster cutting load, no disc warping
• High-quality natural diamond fine 50μm grit delivers consistent smooth cutting performance
• Zero-vibration concentric manufacturing prevents model chipping and uneven cutting lines
• Multi-size specifications (35/45/85/90mm) fit bench grinders and low-speed lab handpieces
• Vent/perforated structures accelerate dust evacuation and heat dissipation to protect plaster models
• Thick durable diamond coating extends service life for high-volume daily lab plaster cutting

1. Stiff steel structure avoids flexible disc bending, keeping straight clean cutting lines on thick plaster blocks
2. Fine 50μm diamond grit leaves smooth plaster surfaces, minimizing extra manual sanding work
3. Vibration-free rotation drastically reduces plaster edge crumble, lowering model scrap rate
4. Dual bore size options adapt to existing bench grinding machines and handheld lab grinders
5. Long-lasting natural diamond coating cuts frequent disc replacement costs for busy prosthetic labs
6. Dust-release vented design prevents plaster debris buildup between grits, sustaining steady cutting speed

1. Full/partial denture gypsum master model separation and excess plaster trimming
2. Orthodontic bracket plaster model cutting, arch form contour shaping
3. Implant model plaster block rough sizing and framework base trimming
4. Casting ring plaster mold split and excess plaster removal before metal casting

1. Premium natural diamond grains offer superior hardness and adhesion vs synthetic low-grade diamond alternatives
2. Strict stiff steel blank thickness control guarantees stable anti-warp performance under heavy load
3. Complete in-stock size range for one-stop lab consumable bulk ordering
4. Flexible MOQ supports small lab trial orders and large distributor wholesale batches
5. Custom OEM service includes private brand laser engraving and customized packaging kit sets
6. Full pre-shipment QC testing for concentricity, diamond coating adhesion and cutting sharpness

Q1: What equipment fits these plaster cutting discs?

A: 20mm bore discs match dental bench grinders; 1.8mm bore discs fit standard dental lab low-speed handpieces.

Q2: Why use stiff steel instead of flexible disc for plaster cutting?

A: Stiff rigid steel ensures straight, clean cuts on thick plaster, flexible discs will bend and create jagged crumbling edges.

Q3: Can this disc trim acrylic denture material?

A: Not recommended; it is optimized for gypsum plaster only, acrylic requires dedicated tungsten carbide trimming burs.

Q4: How to clean and extend disc lifespan?

A: Brush off plaster dust after every use, store flat to avoid bending steel base, avoid overloading cutting pressure during operation.
