Electroplated Diamond Grinding Pins
Electroplated diamond grinding pins are high-precision tools designed for accurate machining of small holes and intricate contours. Manufactured from hardened steel and coated with a uniform monolayer of superhard material grains—such as synthetic diamond or CBN (Cubic Boron Nitride)—through a specialized electroplating process, these pins deliver exceptional performance in demanding grinding applications.
The coating utilizes high-quality lab-grown diamond or CBN abrasive particles, which may include advanced materials like CVD Diamond or precisely selected monocrystal superhard material grains. This ensures outstanding hardness, sharpness, and consistent cutting behavior. The electroplated structure provides excellent grit retention and form-holding capability, allowing the pins to maintain their precise profile throughout extended use.
Exhibiting remarkable thermal stability and wear resistance, these grinding pins are ideal for processing hard and brittle materials such as ceramics, glass, carbides, and hardened steels. Their robust performance also makes them suitable for maintaining and reconditioning diamond cutting tools. Unlike tools based on polycrystalline superhard materials, electroplated pins offer direct and aggressive cutting action with minimal runout and vibration.

Abrasive Types & Recommended Materials
Diamond Grinding Pins
Diamond is the hardest abrasive available. It works best on non-iron and brittle materials such as:
Cemented carbide
Ceramic-metal composites (cermet)
Technical ceramics
Glass, quartz, and optical materials
Ferrites and graphite
Semiconductor wafers
Fiber-reinforced plastics
CBN Grinding Pins
CBN is the second hardest abrasive. It is specially designed for iron-based materials and does not react with steel, making it ideal for:
Hardened steel (above HRC 45)
High-speed steel (e.g., M2, M3)
Tool steel (D2, A2, etc.)
Stainless steel
Cobalt alloys (e.g., Stellite)
Nickel-based heat-resistant alloys
Other hard or difficult-to-machine steels
Main Benefits
High precision: Hardened and centerless-ground shanks provide good balance and stability.
Efficient cutting: The exposed abrasive layer removes material quickly and consistently.
Shape retention: Excellent for machining holes with tight size requirements.
No dressing needed: The electroplated coating keeps its shape through the whole life of the tool.
Custom options: Available in different head sizes, shank diameters, grits, and lengths.
