- Cotton fiber and abrasive grain composition enables grinding and finishing in one step.
- The unique construction continually exposes new abrasive grain during the grinding process resulting in a cooler operation.
- Soft, cushion-like grinding action runs quieter, smooth running and resilient, reducing vibration and chatter.
- Cotton fiber abrasives do not load up when grinding softer metals or alloys such as aluminum.
