Superabrasive Grinding Products

Jowitt & Rodgers Co (J&R) has been providing advanced superabrasive grinding products to a wide range of industries since 1990 through its subsidiary, Syntech Superabrasives. In May 2023, J&R closed Syntech in Charlotte, NC and moved a portion of the operations to our plant in Philadelphia, PA. Our product offerings will be adjusted to reflect our focus on fine grinding applications. We will continue manufacturing select resin and metal bonded diamond and CBN products .


J&R SUPERABRASIVES takes pride in serving our clients in innovative ways to assist them in meeting their goals and objectives. Superabrasive grinding wheels are ideal for extremely hardened surfaces. We will continue finding “creative solutions” in fine grinding to achieve tighter tolerance and finer finishes with exotic alloyed compounds.


Our technical sales and engineering staffs have years of hands-on experience in all types of grinding applications and they are trained to ensure that the solutions we provide meet all of your expectations. We specialize in helping our clients meet their challenges whether it is cost reduction, productivity improvement, or improved tool quality.
