It’s unique fracturing characteristic produces a free cutting action that provides optimal performance when machining nonferrous materials such as tungsten carbide, glass and a variety of ceramics.

Resin bond diamond clad with a metallic coating such as Nickel or Copper may provide additional tool life, as the metal coating improves heat dissipation and the enhanced coating texture improves particle retention in resin bond systems.

RB-50

Very High Friability

Semi Blocky Shape
Density 3.52 g/cm3

Highest friability resin bond diamond particles with a crystal structure that promotes microfracturing. Effective for high precision grinding applications where surface finish is a critical factor.

RB-100

RB-100

High Friability

Semi Blocky Shape
Density 3.52 g/cm3

Economy grade semi-blocky resin bond diamond that is slightly more friable than a standard resin bond diamond. RB-100’s increased friability, coupled with its free cutting action, provides solid performance where cost is a key factor.

RB-150

RB-150

Medium - High Friability

Semi Blocky Shape
Density 3.52 g/cm3

Standard grade blocky resin bond diamond. This medium friability crystal demonstrates an ability to self sharpen which produces a free cutting action that is critical in maintaining the balance between tool life and grinding performance.

RB-200

RB-200

Low - Medium Friability

Semi Blocky Shape
Density 3.52 g/cm3

Premium grade blocky resin bond diamond that is the least friable in our family of resin bond diamond products. Controlled micro-fracturing produces a free cutting action while requiring more force per grain to generate new cutting edges vs. the RB-150.

Resin Bond

systems are widely used for all-purpose superabrasive grinding applications in either phenolic or polyimide bonds. Resin bond systems can be utilized in either wet or dry grinding operations and offer excellent particle retention and part finish.

Vitrified Bond

systems are manufactured from ceramic materials that are strong, durable and brittle. Vitrified bonds are very effective in advanced grinding operations because of their ability to hold the abrasive and reduce heat generation in the grinding zone due to their high porosity levels when compared to other bond types.
