Jincheng brand diamond segments fitting core drills and saw bodies from 12 mm to 600 mm, covering standard, turbo and corrugated profiles for reinforced concrete, granite, marble and ceramic cutting.
A high-cobalt matrix raises wear resistance across stone and concrete, leaving a clean cut face.
Engineered for the hardness and abrasiveness of granite, using fine high-concentration diamond in a wear-resistant matrix. Fast cutting with minimal chipping — for bridge saws and multi-blade machines cutting granite and marble.
Key features: · Granite-specific formula · High-concentration, wear-resistant diamond · Minimal chipping, higher slab yield · For bridge saws and multi-blade machines
All products use premium diamond grit and imported matrix powders, processed by hot-press sintering, laser welding and piece-by-piece inspection. Hardness, density and bond strength are sampled before shipment to guarantee batch-to-batch consistency.
OEM/ODM supported: dimensions, matrix hardness, diamond concentration, threads and connections can be customized to your drawings or rock conditions. Neutral packing and private label available; samples in 7–15 days.
Factory-direct pricing with no middlemen. Our technical team advises on model selection and drilling parameters. Fast delivery with ample stock of standard sizes.

Description from the Supplier
The following content is provided by the manufacturer, covering product features, factory advantages and how to work with us.
Product Description
Diamond Segments · High Quality Diamond Segment for Concrete and Granite or Marble Cutting
Diamond segments are divided into core-bit segments and saw-blade segments, with roof-top, flat, net and great-wall profiles, covering engineering coring from 18 mm to 600 mm and saw blades from 100 mm to 3,500 mm. They are made with imported cobalt and nickel powders and high-quality diamond single crystals, using a scientifically validated formula and advanced sintering processes.
Segments cut granite, marble and concrete fast and sharply without chipping, with long life and stable performance. Segment size, diamond grit and concentration, and matrix hardness (25–45 HRC) can all be customized to the stone hardness and your machine.
Product Advantages
More than 20 years of professional experience in diamond tools; the factory has been producing synthetic diamond tools since 2009.
Factory-direct supply: we are the manufacturer, with no middleman — better prices at the same quality.
High-grade raw materials: imported cobalt and nickel powders and high-quality diamond single crystals, with a formula validated by testing.
Advanced processes and strict inspection: hot-press sintering, vacuum brazing and laser welding, with piece-by-piece inspection and sampling of hardness, density and bond strength.
Efficiency and life: PDC anchor bits last 10–30 times longer than tungsten-carbide bits and raise efficiency by about 60%; impregnated bits drill fast with a long service life.
Full range and customization: AQ–PQ and T2/T6 series, common sizes 24–600 mm; matrix hardness, diamond concentration, threads, packing and buyer labels can all be customized (OEM/ODM).
Fast response and reliable lead time: enquiries answered within 10 hours, about 7 days delivery when the mould is ready and about 12 days when a new mould is required.
Packing & Delivery
Standard packing is an inner box in a thick export carton; neutral packing or your own packing method is available on request. Port of shipment: Guangzhou / Shenzhen. Trade terms: FOB, CFR, CIF, EXW. Payment: T/T, L/C, D/P, Western Union and PayPal.
