Diamond Wheels

Diamond Wheels

Eagle Superabrasives offers 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

Hybrid bond wheels are the industry leader in the manufacturing of solid carbide endmills, drills and reamers.

Eagle Superabrasives’ hybrid bonds utilize a unique bond system offering superior tool edge retention and stock removal rates that were unheard of a few years ago.  Our bond system is comprised of a mixture of specially selected alloys, ceramics, diamond powders and coatings, all sintered in environmentally-controlled furnaces.

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, longer spindle life and no thermal damage to the tool.

We are currently able to manufacture hybrid bond wheels up to 10″ diameters.

RESIN BOND Diamond Wheels

Resin bonds are the most commonly used bond system for superabrasive grinding wheels. They are 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, all at an affordable price.

Resin bond wheels come in two varieties: Phenolic and Polyimide.

  • Phenolic resins are typically used for wet or dry grinding, off-hand grinding, centerless grinding and general purpose tool room use.
  • Polyimide resins offer a considerable performance increase over generic phenolic resins. You can expect to see greater stock removal, better form holding, higher temperature tolerance and minimal wear when grinding with polyimide bond wheels.

At Eagle, we manufacture resin bond wheels up to 30″ in diameter every day.


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

These wheels are extremely aggressive and free cutting. They provide excellent tool life, require less stoppages for dressing than their resin bond counterparts, are cool-cutting and are suitable for “lights out” high production grinding.

Eagle vitrified bonds range from 3/16″ diameter all the way to a 40″ segemented diameter.

METAL BOND Diamond Wheels

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

Metal bond wheels offer the best grit retention and a very long service life. They are industry-leading for form holding, but require high horsepower machinery and are significantly slower cutting than resin bonds and other bond systems.  Metal bonds work best when grinding a very abrasive material.

Eagle metal bond wheels start at a minimum diameter of 3/8″, and max out at 16″.
