Diamond Corner Drill Cone

The diamond corner drill cone is designed to help you grind into corners, stairs, under cabinetry, curves, and bevels. It is perfect for faster material removal on concrete and hard-to-reach corners.

Our grinding cones come in two variants, 120 grit for fine concrete grinding, and 30 grit for an initial cut or a more aggressive grind/removal. The Corner Grinding Cones are designed to fit with an 8mm shaft for use in Electric/Battery Variable speed drills.

The Corner Grinding Cone attachment is also compatible with Die Grinders or Drills, making it versatile and easy to use. Try our Triangular Grinding Tool today and get the perfect finish for your concrete grinding needs.
