- Next-generation ceramic alumina abrasive grain for significantly faster cut rates, resists wear, resulting in 50%-300% longer life, greatest productivity
- X-wt. cotton cloth and resin bond for excellent grain retention and life
- Improved resin bond system for improved grain retention and longer life
- Advanced grinding aid for cooler cutting, longer life
- 36-60 grit is recommended for removing heavy burrs, stock removal, removing flash and parting lines and removing rust, scale and pit marks
Spiral rolls are strips of abrasive cloth rolled and glued to form a solid shape that is designed to break down during use and reveal the next layer of abrasive. There are mounted on a mandrel and used on high speed grinders for grinding, finishing and polishing channels, fillets and radii and deburring small holes.
