01 / Material families
CBN abrasive grains are not the same product as a PCBN cutting composite. PCD machining materials and PDC drilling cutters also serve different workpieces and tool geometries.
Ferrous metal grinding
Synthetic CBN grains for resin, vitrified, metal or electroplated abrasive-tool systems. Consider crystal morphology, friability, grit size, grinding duty and bond compatibility.
Series: CBN-A10 / A20 / B10 / B20
Explore CBN MaterialsPrecision machining
Polycrystalline diamond tool materials used in selected non-ferrous machining, abrasive composites, graphite and similar applications. Evaluate cutting edge, workpiece and tool construction.
Selection focus: substrate, tool geometry, grade and processing regime.
Explore PCD ToolsFerrous material cutting
CBN-based polycrystalline cutting materials for demanding ferrous machining. Unlike loose CBN abrasive grit, PCBN is a consolidated cutting-material system selected by cutting conditions and geometry.
Selection focus: workpiece hardness, operation, insert geometry and cutting regime.
Explore PCBN CompositesDrilling & geological tooling
Diamond-table cutting elements bonded to a substrate, commonly selected for drilling and other specialized high-wear tool designs. Examine cutter geometry, formation and impact-abrasion balance.
Product paths: oil & gas, mining / geology, milling / cutting.
Explore PDC Cutters02 / CBN grade reference
SinoDiam's four familiar CBN grades vary in crystal shape and intended abrasive-tool conditions. The table is a discussion framework—not a guarantee of output or universal interchangeability.
CBN A10 · Amber / irregular
Irregular amber CBN chosen for selected resin-bond grinding applications; review friability and desired self-sharpening behavior.
View CBN-A10CBN A20 · Amber / regular
More regular-shaped amber crystals considered for selected vitrified, metal-bond and electroplated tool designs.
View CBN-A20CBN B10 · Black / friable
Friable black CBN, often evaluated for resin-bond applications where controlled particle fracture and finishing behavior matter.
View CBN-B10CBN B20 · Bright black / blocky
Blocky black CBN to evaluate where crystal toughness, grinding load and tool operating conditions are key parameters.

CBN grit, PCBN cutting materials, PCD and PDC all belong to advanced superabrasive supply, yet they solve different problems in grinding, precision machining and drilling.
| Material | Supplied material system | Typical workpieces / uses | What to confirm |
|---|---|---|---|
| CBN Grit | Discrete abrasive grains for bond-tool production | Hardened steel and selected ferrous grinding operations | Bond type, grain shape, mesh, grinding load and finish |
| PCD | Polycrystalline diamond cutting material / tools | Aluminum, copper, composites, graphite and selected abrasive non-ferrous workpieces | Tool geometry, grain structure, machine and cutting regime |
| PCBN | Consolidated polycrystalline CBN cutting material | Hardened steels, cast iron and selected ferrous precision machining | Workpiece hardness, cutting parameters, grade and insert configuration |
| PDC | Polycrystalline diamond cutting table with supporting substrate | Oil and gas drilling, mining, geology and related specialized cutters | Formation, abrasion / impact duty, cutter size, shape and mounting |
Typical applications only. Final grade, manufacturing construction, limits and performance must be assessed against the specific tool design and operating conditions.
04 / Application paths
Different toolmakers may start with similar material names but need very different final product constructions.
CBN abrasive grades for resin, vitrified, metal and plated grinding systems.
CBN Grit →PCD materials for selected aluminum alloys, copper, graphite and abrasive composites.
PCD Materials →PCBN cutting composites evaluated for ferrous workpieces, edge design and cutting parameters.
PCBN Composites →PDC cutter systems for drilling designs with defined rock formation and load requirements.
Oil & Gas PDC →Polycrystalline diamond cutting elements for drilling and geological tool configurations.
Geological PDC →Distinguish micron diamond feedstock for polycrystalline production from finished cutting products.
SND-M/PCD Powder →05 / Technical selection workflow
A material recommendation should be based on application conditions, not just a catalog name.
06 / Manufacturing & technical supply
SinoDiam supports technical material selection, processing discussions and international sourcing across several superabrasive categories.
China operations include industrial diamond and superabrasive product development, manufacturing coordination and specialized processing, together with technical communication for CBN, PCD, PCBN and PDC inquiries.
The Thailand operation focuses on crushed diamond, micron diamond powders and selected coated diamond materials. It should not be assumed to manufacture every advanced superabrasive family listed on this page.
07 / Technical questions
These answers support initial material discussions. Final product choice requires the applicable technical datasheet and process validation.
CBN grit is supplied as individual abrasive grains used in grinding tools. PCBN is a consolidated polycrystalline CBN cutting material used in certain turning and machining operations. They are not interchangeable product forms.
PCD is commonly considered for non-ferrous metals, graphite and selected abrasive composites; PCBN is considered for hardened steels, cast iron and other suitable ferrous applications. Check tool geometry and cutting conditions.
They differ in crystal color, morphology and intended grinding/bonding considerations. A10 is irregular amber, A20 more regular amber, B10 friable black and B20 blocky black. Confirm current mesh and technical specifications before selecting.
No. PDC cutters are a specific composite cutting-element construction often used in drilling or geological tools, commonly involving a polycrystalline diamond table and supporting substrate. PCD machining tool materials are selected for different cutting geometries and workpieces.
No. SND-M/PCD is a micron diamond powder for selected polycrystalline material manufacturing processes. Finished PDC cutters are separate products with their own dimensions, constructions and application requirements.
Please share your material or formation, processing method, desired product family, any known grade or dimensions, expected order volume, destination and target schedule. When available, include tool drawings and current trial results.
