Diamond Wheels

Diamond Wheels

At Eagle Superabrasives, Inc. we offer Diamond grinding wheels in four different bond types as listed below. Each bond type has unique properties and should be carefully selected to obtain the best grinding results.

HYBRID BOND Diamond Wheels

Used in the manufacture of solid Carbide End Mills, Drills and Reamers.

Our unique bond systems, comprising of a mixture of specially
selected alloys, ceramics and diamond powders and coatings, all sintered in environmental controlled furnaces, offer stock removal rates and tool edge retention that were unheard of only a few years ago.

Hybrid bonds have now become the industry standard bond type for all manufacturing of end mills, drills and reamers.

They offer the benefits of hugely reduced cycle times, with material removal rates of up to 10 times that of any resin bond product, wheel edge retention of more than 20 times that of resin bond wheels, lower spindle load, excellent thermal stability, reduced tool deflection plus longer spindle life and no therrmal damage to the tool .

Manufacturing capabilities of up to 10” Diameter

RESIN BOND Diamond Wheels

Resin bond is the most commonly used bond system that is used for grinding all types of Tungsten Carbide tools, Ceramics, Glass, ferrites, refractories and semi-conductors. It offers good elasticity, superior surface finish and highly efficient grinding performance at a very cost effective price

  1. Phenolic Resins. Typically used for wet or dry grinding, off-hand grinding, centerless grinding and general purpose tool room use.
  2. Polyimide Resins. These resins offer considerable
    performance increase over phenolic resins. Greater stock
    removal, better form holding, higher temperature tolerance
    and minimal wear are all benefits of polyimide body

Manufacturing capabilities of up to 27” diameter


Vitrified bond systems are typically selected for grinding PCD and PCBN tools, ceramics and semi-conductors.

Vitrified bond wheels are extremely aggressive and free cutting. They provide excellent tool life, need dressing much less than resin bonds, are cool cutting and are suitable for “lights out” high production grinding.

Vitrified Bond – Min. Diameter 3/16 in. / Max. Diameter 40 in. (Segmented)

METAL BOND Diamond Wheels

Typical applications for metal bonds are grinding glass, ceramics, refractories, ferrites, tile, stone and quartz.

Metal bond offers the best grit retention and a very long service life. Form holding is the best available, but it requires high horsepower machinery and is much slower cutting than resin bonds for example and works best when a very abrasive material is being ground.

Metal Bond – Min. Diameter 3/8 in. / Max. Diameter 16 in.
