Ohio Tool Works is proud to offer the popular Sunnen Style "G25, M27, N37 and W47" series abrasive mounts for the Portable Tool System. The "Portable Replacement" series is available in both conventional vitrified grades as well as metal-bonded diamond and CBN, and in 2-stone or 4-stone configurations.

The OTW series abrasive sets are completely interchangeable with the Sunnen stones and can be used both on hand-held setups or most light-duty machines using portable tooling system.

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