For nearly 50 years, Global Diamond Co., Ltd. has been providing our customers with the best possible products, taking into account the infinite applications and possibilities of diamonds—the hardest substance on Earth—as well as the ever-changing trends in processing technology and the global economic landscape.
Industrial synthetic diamonds
Synthetic diamonds produced using high-pressure equipment are available in a variety of grades and sizes, primarily for use as tooling materials.
Diamond powder
Synthetic diamonds, primarily produced using the high-pressure, high-temperature (HPHT) method, are indispensable as tool materials for cutting, grinding, and polishing hard-to-machine materials. We will introduce them by abrasive grain size.
Saw Size
Coarse-grained diamond abrasives primarily used in tools for stone processing and civil engineering applications
Mesh size
Diamond abrasives with a finer grain size than saw-size, primarily used in machining applications as grinding and cutting wheels
micron-sized
Precision-graded diamond abrasive grains with a particle size generally of 50 μm or less, finer than the mesh size
Polycrystalline diamond
A synthetic diamond produced by the explosion method, primarily used for polishing applications
Special shapes
Synthetic diamond particle products in various shapes
Diamond-coated material
Diamonds synthesized using the chemical vapor deposition (CVD) method are expected to serve not only as materials for cutting tools and optical components, but also as next-generation materials for applications such as substrates.
CVD single-crystal diamond
A single-crystal diamond produced by the CVD method.
CVD polycrystalline diamond
A polycrystalline diamond produced by the CVD method.
Industrial natural diamonds
Natural diamonds, which do not contain catalysts or metallic components used in the production of synthetic diamonds, are highly friable and are characterized by their sharp cutting edge.
Industrial natural diamonds
We handle products ranging from inch-sized to micron-sized.
CBN
CBN (cubic boron nitride), which is second only to diamond in hardness, maintains stable properties even under high-temperature conditions and is widely used as an abrasive grain for machining iron-based materials where diamond powder is not suitable.
Mesh Sized CBN powder
CBN abrasive grains with a particle size of 35 μm or larger, finer than saw-cut size
Micron-sized CBN powder
CBN abrasive grains with a particle size of 50 μm or less
Other Products
Here we introduce high-quality slurries featuring PCD (sintered diamond), available only from a trading company specializing in diamond products.
