Diamond segments price

The most critical factor is matching the bond hardness to the material's abrasiveness. For hard materials like granite or quartz, use a soft bond so that the metal wears away fast enough to expose new diamonds. For abrasive/soft materials like sandstone or asphalt, use a hard bond to prevent the segment from wearing down prematurely. Always specify the Mohs hardness of your target stone to the supplier.

Performance is driven by diamond concentration and grit size. A higher concentration (e.g., 25-30%) generally extends the lifespan but may slow down the cutting speed if the machine power is low. Grit size (e.g., 30/40 or 40/50 mesh) affects the finish; coarser grits are for fast, rough cutting, while finer grits provide a smoother edge. Ensure the segment height (typically 10mm to 20mm) is consistent across the batch to prevent vibration.

Sandwich segments have a higher diamond concentration on the outer layers to maintain a straight cut and prevent 'tapering.' Multi-layer segments provide stable cutting speed throughout the segment's life. Arrayed (Arix) technology places diamonds in precise patterns, offering the highest cutting efficiency (up to 30% faster) and the longest life, though at a higher price point.

For dry cutting, Laser Welding is mandatory to prevent segment loss, which can be extremely dangerous. For wet cutting, High-Frequency Silver Brazing is the industry standard. Ensure the supplier uses silver solder with at least 30-40% silver content to guarantee a strong bond between the segment and the steel core, especially for large diameter blades (over 1200mm).

Never skip the sample testing phase. Request a small batch to test on your specific machinery. Use a Schmidt Hammer or a hardness tester to verify bond consistency. On Made-in-China.com, look for suppliers with Audited Supplier status and check their Bureau Veritas (BV) or SGS inspection reports to ensure their factory capacity matches their claims.

Negotiate based on Total Linear Meters Cut rather than just the unit price. A cheaper segment that wears out twice as fast is more expensive in the long run. Ask for tiered pricing (e.g., 500 sets vs. 2000 sets) and request customized formulas for your specific region's stone types. Professional suppliers on Made-in-China.com are usually willing to adjust the metal powder mix to win long-term contracts.

Diamond segments are heavy and dense; Sea Freight is the most economical for bulk, but ensure the packaging is moisture-proof (vacuum sealed) to prevent oxidation of the metal powders. Check your local Anti-Dumping Duty (ADD) regulations, as some countries impose high tariffs on diamond tools from specific regions. Ensure the supplier provides a Certificate of Origin to help with customs clearance.

Utilize Secured Trading Services provided by Made-in-China.com to ensure payment is only released after the goods are shipped. For large orders, hire a third-party inspector to perform a 'During Production Check' (DUPRO) to verify that the diamond grade used in the middle of the batch is the same as the samples provided.
