Precision Corner Grinding Tool for Concrete, Stone & Hard-to-Reach Areas

The Ballistic Diamond Corner Grinder is a professional-grade precision grinding tool designed for finishing corners, edges and other areas that standard grinding cups and floor grinders simply cannot reach. Manufactured using premium industrial diamonds, these high-performance corner grinders deliver fast material removal, excellent control and long service life on concrete, masonry, stone and other hard building materials.

Available in 25/30 Grit, 60 Grit and 120 Grit, the Ballistic Corner Grinder allows contractors to progress through multiple grinding stages while maintaining a consistent finish throughout the project. Its conical diamond head provides easy access into tight internal corners, around columns, staircases, expansion joints and detailed concrete work where conventional tooling is ineffective.

Whether you’re preparing concrete for epoxy flooring, removing imperfections, cleaning inside corners or refining detailed work before polishing, the Ballistic Corner Grinder is an essential accessory for every professional flooring contractor.
