SinoDiam Metallic Coating Diamond Series: Compare 5 Products & Pick Yours in 2 Minutes
If you’re a tool manufacturer, grinding wheel maker, or industrial machinist searching for “best coated diamond for my bond type” or “how to stop diamond falling off tools”, you’re in the right place.
SinoDiam’s Metallic Coating Diamond Series includes:
Titanium-Coated, Nickel-Plated N30 (30%), Nickel-Plated N56 (56%), Titanium Carbide-Coated, and Surface-Etched Diamonds—engineered for maximum adhesion, heat resistance, and precision.
This guide breaks down the 5 products side by side, so you can quickly see:
✅ What it does
✅ Which bonds it works with
✅ When to choose it
Why Choose Metallic Coating Diamonds?
Uncoated diamonds often fail in industrial tools: they fall off matrices, react with metals, or degrade under heat. SinoDiam’s coated and surface-etched diamonds solve these problems with:
- 🔗 Strong Adhesion: Coatings or pit-like textures “lock” diamonds into metal, ceramic, or resin bonds.
- 🔥 Heat & Chemical Protection: Prevents diamond damage from hot-press forming, welding, or chemical reactions.
- ⚡ Better Tool Performance: Reduces tool wear, processing noise/current, and ensures clean, precision surfaces.

Pick the Right Diamond in 3 Questions
1️⃣ Do you use electroplated tools?
→ Only Surface-Etched Diamond works. Coatings can ruin electroplating layers—its pit-like surface improves adhesion without coating.
2️⃣ What bond type do you mainly use?
- Resin bond only: Nickel-Plated N56 (56% Ni, spiny surface = maximum grip)
- Metal/ceramic bond only:
- Titanium-Coated (best heat protection for hot-press tools)
- Titanium Carbide-Coated (clean surface, tough workpieces)
- All bond types (metal, ceramic, resin): Nickel-Plated N30 (30% Ni, multi-bond = no extra inventory)
3️⃣ Do you need to avoid workpiece contamination?
→ Titanium Carbide-Coated Diamond is inert, ideal for precision parts, e.g., high-alloy steel, aerospace, automotive, or medical tools.
Real-World Applications
- Hot-press tool makers: Titanium-Coated Diamond extends tool life by 30%, prevents diamond fall-off.
- Mixed-bond shops: N30 handles metal, ceramic, and resin—reduces inventory headaches.
- Precision resin polishing: N56’s spiny nickel coating keeps diamonds in place, polishing 45% more parts.
- Electroplated saws: Surface-Etched Diamond cuts noise by 15dB and reduces processing current by 20%.

FAQ – Quick Answers
Q1: Can I use N56 for metal bond tools?
A: No. Its 56% Ni and spiny surface are designed for resin and ceramic tools. Metal bond tools require heat-resistant diamonds like N30 or Titanium-Coated.
Q2: Titanium-Coated vs Titanium Carbide-Coated – what’s the difference?
- Titanium-Coated: heat shield for metal/ceramic hot-press tools.
- Titanium Carbide-Coated: inert shield for clean, tough workpieces, preventing contamination on high-alloy steel or precision parts.
Q3: Can I get finer mesh than 325/400 or 500/600?
A: No. These are coarse-particle products for industrial cutting, grinding, and hot-pressing. For fine polishing, see our Micron Diamond Series (e.g., SND-M15, M05).
