1. Introduction: Heavy-Duty Saw Cutting Synthetic Diamond Grains
In stone processing, quarrying, construction sawing, and geological core drilling, diamond grains encounter severe thermal shock, extreme impact loads, and abrasive friction. GDM Diamond's official 92 Series Saw Cutting Diamond Powder is specifically synthesized to satisfy these aggressive heavy-duty operations. The 92 Series encompasses four distinct crystal strength grades: 9220, 9230, 9240, and 9260.
2. Detailed Breakdown of 92 Series Diamond Grades
GDM 9220 Grade — Low-Load Light Sawing & Soft Stone Polishing
Regular yellow crystal with moderate blockiness and higher friability. Suitable for soft marble slicing, abrasive stone polishing, and low-load electroplated saws where fast free-cutting is prioritized over high impact resistance.
GDM 9230 Grade — Medium-Load General Construction Saws
Semi-blocky monocrystalline grains with balanced impact strength and thermal toughness. Engineered for asphalt cutting blades, green concrete saws, and medium-hard marble circular saw blades.
GDM 9240 Grade — Middle-High Strength Granite & Wire Saws
High-strength cubo-octahedral crystals with smooth crystal faces, high thermal stability (TTI), and low magnetic impurity levels. The industry standard for multi-wire granite saws, gang saws, and hard stone slitting segments.
GDM 9260 Grade — Maximum Strength Mining & Reinforced Concrete Saws
Premium high-grade monocrystalline diamond with complete blocky crystal geometry, zero micro-fissures, and maximum Thermal Toughness Index (TTI >1100°C). Designed for heavy geological mining bits, reinforced concrete wire sawing, and hard granite quarrying.
