- 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
- 80-120 grit for deburring, blending, cleaning and applying a light scratch pattern
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.
