SND Micron Diamond Guide:
If you’ve ever stared at a list of micron diamond grades and thought: “Do I need M10 or M15 for gem polishing? Is M/PCD only for PCD tools? Can MDW work for my silicon wafer cutting?”—you’re not alone.
SinoDiam’s SND micron diamond series (M05, M10, M15, M/PCD, MDW) isn’t a “one-size-fits-all” lineup. Each grade is engineered for a specific purpose: some prioritize budget-friendly grinding, others precision diamond polishing, and a few are tailored to niche applications like PCD tool manufacturing or diamond wire cutting. This guide breaks down the differences clearly—so you can choose the right grade in 5 minutes without technical jargon.
Quick Overview: What Each Grade Does Best
Here’s a one-sentence summary of each SND micron diamond powder grade, your “quick reference cheat sheet”:
- SND-M05: Economy-grade for basic grinding and pre-polishing (tiles, jade), ideal for budget-conscious workshops.
- SND-M10: Mid-tier, versatile for multi-material polishing (gems, glass, ceramics), balancing cost and performance.
- SND-M15: Premium precision for ultra-smooth polishing and finishing (aerospace parts, luxury gems).
- SND-M/PCD: Specialized for PCD/PDC tool manufacturing, where ultra-low impurities are critical.
- SND-MDW: Expert for diamond wire and saw cutting, perfect for silicon wafers and hard/brittle materials.

FAQ
Q1: Can I use M10 instead of M/PCD for PCD tools?
A: Not recommended. M/PCD’s ultra-low silicon (≤0.01%) is critical for avoiding cracks. M10 has higher impurities (≤0.3%).
Q2: Can M15 cut silicon wafers?
A: No, M15 is for polishing, not cutting. MDW is designed for high-tension diamond wire cutting.
Q3: Polishing jade—M05 or M10?
A: Pre-polishing → M05. Final glossy polish → M10.
