Ohio Tool Works is proud to offer the popular Sunnen Style "H50 & H70" series abrasive mounts for the MPS Tool System. The "OH" series system is our replacement for the Sunnen "H" series abrasive sets and is available in both conventional vitrified grades as well as metal-bonded diamond and CBN.

Our "OH" series abrasive sets are completely interchangeable with the Sunnen machines such as the "HL", "STH", "HTB", "HLH" or any machine using a MPS modular tooling system. And compared with the competition, OTW's OH Series offers 11% more usable abrasive for longer stone life and sulfer fill for cleaner cutting (no loading) at no extra cost.

The direct interchange, competitive price, large selection, off the shelf delivery and more usable abrasive will help to reduce the costs of your honing operation.

OH500 Series consists of two (2) abrasive assemblies.

OH700 Series consists of two (2) abrasive assemblies and two (2) guides.
