Import Diamond Blade For Dry Cutting — Buy in Bulk from Supplier in China

This diamond blade is engineered for dry cutting of hard natural stone such as granite and marble, with a segment height of 8 mm and a core thickness of 1.2 mm, as stated in the product data. The blade is designed for use with standard 125 mm to 230 mm angle grinders and circular saws, with a bore diameter of 20 mm to accommodate common arbor sizes. Its diamond concentration is rated at 75%, and the bond hardness is formulated for medium to hard stone applications, ensuring consistent wear and prolonged cutting life under high-friction conditions.

The diamond segments are electroplated with industrial-grade synthetic diamonds in a nickel matrix, a standard method for dry-cutting blades where coolant is not used. The core is made from high-carbon steel with stress-relieved tempering to resist warping during extended use. While the listing does not specify the exact diamond grit size, typical blades for this application use 50/60 mesh for general cutting and 80/100 mesh for finer finishes. The absence of water cooling requires the blade to dissipate heat through air flow and segment design, making segment spacing and venting critical to avoid glazing.

This blade is purchased by stone fabricators, masonry contractors, and renovation crews working on commercial and residential projects where dust control is prioritized over wet cutting. Buyers typically order in batches of 50 to 200 units, with packaging in cardboard boxes of 10 blades each. Trade terms are commonly FOB Qingdao or CIF destination port, with lead times averaging 15 to 25 days after order confirmation. The blade is not certified to ISO or CE standards as claimed in the source text; buyers should request test reports for segment adhesion and rotational safety before bulk purchase.
