SND-G Series RVD Diamond Guide: Choose G05, G10, or G15 for Your Project (3-Way Comparison)
If you’re an SME cutting ceramic tiles, a luxury stone polisher working on hotel lobbies, or an industrial manufacturer grinding aerospace parts, choosing the right RVD diamond is critical for both budget and performance. SinoDiam’s SND-G series (G05, G10, G15) is specifically designed to meet these diverse needs. Whether you’re focused on cost-effectiveness or high-precision work, there’s a perfect match for your project.
Here’s a quick breakdown of the SND-G series:
- SND-G05: Budget-friendly for low-to-medium tasks (e.g., home stone renovations).
- SND-G10: Precision-focused for high-gloss finishes (e.g., marble polishing).
- SND-G15: Industrial-grade for tough, high-load work (e.g., carbide cutting).
Below, we break down their differences in a 3-way comparison table, plus show you how to pick the right one in just 2 minutes.

How to Pick the Right SND-G Grade in 2 Minutes
Use this simple framework to match your project to the right grade:
- If you’re on a budget (SMEs, local shops)
Choose SND-G05 if:- You’re cutting or edging low-to-medium intensity materials (e.g., ceramic, residential stone, ordinary glass).
- You need to simplify inventory (80–500 mesh covers all common sizes).
- You want to save 20% on annual tool costs without sacrificing basic performance.
- Example: A small NA glass shop uses G05 for window pane chamfering—they replace wheels every 80 hours (vs. 65 hours with generic RVD) and save $500/year on procurement.
- If you need precision & high gloss (luxury stone, jewelry)
Choose SND-G10 if:- You’re polishing medium-hard stones (e.g., marble, granite) or trimming carbide molds.
- Surface quality is critical (e.g., luxury hotel floors, jewelry-grade diamonds).
- You want to reduce rework (15% lower stone reject rates).
- Example: An EU marble processor uses G10 for hotel lobby polishing—they achieve a 90° gloss finish in one step (vs. two steps with cheaper RVD) and cut project time by 25%.
- If you need industrial durability (aerospace, mining)
Choose SND-G15 if:- You’re working with hard materials (e.g., basalt, aerospace alloys, carbide).
- You need tools to handle high loads (e.g., highway construction, turbine polishing).
- You want to lower TCO (30% ROI within 6 months via fewer replacements).
- Example: A NA aerospace supplier uses G15 for turbine blade polishing—tools last 2–3x longer than standard RVD, and post-processing time drops by 25%.
FAQ: Your SND-G Series Questions Answered
Q1: Can I get custom mesh sizes for any SND-G grade?
A: Yes! G05 offers 80–500 mesh (standard), while G10 and G15 can be customized for bulk orders (e.g., 60/80 mesh for G15 industrial grinding, 400/500 mesh for G10 jewelry pre-shaping). MOQ: 25kg for G10 and 50kg for G15.
Q2: Is SND-G15 compatible with metal bond tools common in NA/EU?
A: Absolutely! G15 is engineered for all industrial bonds, including metal bond (used in heavy-duty grinding discs for highway construction). Its uniform shape ensures strong adhesion, even at 850°C—perfect for high-load tasks.
Q3: Is SND-G05 less durable than G10/G15?
A: G05 is designed for low-to-medium tasks and lasts 80–100 hours in ceramic/glass processing—ideal for SME cycles. For high-load work (e.g., hard rock grinding), G10/G15 are more durable, but G05 offers unbeatable value for budget-focused projects.
