Diamond Grinding Discs DGD
Long Life Surfaces with Consistent Results
Buehler diamond grinding discs (DGD’s) offer extended life, high removal rates, increased efficiency and consistency and reduced waste relative to silicon carbide paper.
They are a great choice for many grinding applications including grinding very hard materials that silicon carbide paper may not effectively grind.
Process a Variety of Materials
Buehler offers multiple different types of diamond grinding disc products depending on the material being processed as well as the speed and surface quality needed.
Only an occasional dressing is required with some materials to maintain the surface.
DGD Color
Our most versatile diamond grinding disc, the unique characteristics of the resin bond used provides long life and high removal rates on most materials, including ductile materials, most metals and polymers.
DGD Color discs are available with PSA or Magnetic backing in abrasive sizes from 8 micron to 240 micron.
DGD Terra
Resin-bonded DGD Terra provides a very gentle removal rate with excellent flatness and surface quality making it an excellent choice for brittle and delicate materials (e.g. ceramics, glass).
DGD Terra discs are available with PSA or Magnetic backing in abrasive sizes from 0.5 micron to 165 micron.
DGD Ultra
The metal bond in DGD Ultra disc makes it more durable than resin bond, and it works great for grinding highly abrasion-resistant materials such as cemented carbides and very hard ceramic.
DGD Ultra discs are available with PSA backing in abrasive sizes from 6 micron to 125 micron.

Frequently Asked Questions
How do I store my DGDs when not in use?
Are there any working parameters recommended while working with DGDs?
When grinding with DGD’s use of 300 RPM (base) and 60 RPM (power head) generally provides optimal material removal, thus greatest grinding efficiency. Always grind with water coolant, adjust water flow such that the disc remains wet yet not saturated with copious water flow as this may reduce grinding rate.
For most materials 5 pounds per square inch surface area is ideal, this translates into ~ 4lbs/1” or 30mm sample, 5lbs/1.25” sample, 7lbs/1.50” or 40mm sample, ~ 12lbs/2” or 50mm sample. When working with highly abrasion-resistant materials (very hard ceramic, carbides, refractory alloys) increase pressure to ~6lbs. per square inch.
When should I use a dressing stick?
Which dressing stick should I use?
How do I use a dressing stick?
What can I do if I don't have a dressing stick?
In the event no dressing stick is available, one can use a stiff nylon brush to clean DGD’s though this is not quite as effective as a dressing stick.
