SND830 Saw Grit Diamond
Description:
SND830 Saw Grit Diamond is a budget-friendly synthetic diamond grit (purity ≥99.5% carbon content) featuring a semi-blocky crystal structure—designed for ease of bonding and consistent performance in routine applications. It offers several key benefits, including:
- Low-to-Medium Toughness: With a Vickers hardness of 6,000–6,500 HV, SND830 can withstand light-to-moderate impact (up to 8–10 N) without fracturing. Ideal for tasks like trimming soft stone or grinding concrete.
- Reliable Thermal Stability: It maintains performance at temperatures up to 800°C, preventing softening during extended grinding tasks like polishing concrete surfaces.
- Cost-Efficiency: Priced 25–30% lower than mid-tier SND840, SND830 provides 75% of SND840’s wear performance, making it perfect for high-volume, low-demand tool production (e.g., disposable construction blades).
When used for manufacturing blades, grinding wheels, or general-purpose tools, SND830 consistently delivers value: it reduces upfront costs by 30% compared to SND840, while offering 15–20% longer life than generic budget grits. It is best suited for tasks where tool replacement is frequent or performance demands are low.
Available Grit Sizes:
18/20, 20/25, 25/30, 30/35, 35/40, 40/45, 45/50, 50/60 mesh (particle size range: 0.250mm – 1.00mm), with size tolerance controlled within ±6% of nominal value. This ensures compatibility with standard bonding processes and predictable performance across batches.
FAQ:
Q1: What tasks is SND830 best suited for?
A1:
SND830 excels in low-to-moderate-demand tasks such as:
- Small-scale construction (trimming soft brick, cinder block)
- Home renovation (grinding concrete floors)
- Light stone processing (cutting porous limestone)
- General manufacturing (deburring metal parts with diamond grinding wheels)
It is not recommended for hard rock or high-speed cutting, for which SND860 or SND890 would be better choices.
Q2: How long does SND830 last?
A2:
For routine tasks (e.g., grinding 100m² of standard concrete), SND830-equipped tools typically last 8–12 hours of continuous use—20% longer than generic budget grits but 30% shorter than SND840. It’s designed for “disposable” or short-cycle applications, such as one-off construction jobs where affordability is a priority over tool lifespan.
Q3: What bonding systems work best with SND830?
A3:
SND830 is compatible with low-cost bonding systems like resin and basic metal matrix—commonly used for entry-level tools.
- Resin bonding is ideal for light grinding (e.g., woodworking diamond sandpapers).
- Basic metal matrix bonding works well for small construction blades.
Its semi-blocky crystal structure ensures good adhesion, even with simpler bonding processes (no need for high-temperature sintering).
Q4: Can SND830 be mixed with higher-grade grits?
A4:
Yes! SND830 can be mixed with SND840 or SND860 (in a 1:1 ratio) to balance cost and performance. For example, combining SND830 with SND840 reduces tool costs by 15%, while maintaining 90% of SND840’s wear life. This combination is perfect for manufacturers making mid-range tools for small businesses, such as local stone workshops.
