Sidley Diamond Tool Company prides itself on being a leader in creating high-quality, custom diamond dressing rolls for a wide range of applications.


Custom Diamond Dressing Rolls - Sidley Diamond Tool Company - dressing1A Sidley diamond dressing roll is a cylindrical tool with diamond particles embedded in the periphery. The diamond area is qualified to the required form and then is ready to use.

In use, the roll is rotated and fed into the grinding wheel, forming the abrasive grain of the wheel.

The advantages of using this type of product versus single-point tools or a crush dressing are its speed, a tool life of thousands of parts and consistency of parts produced.
