60 Degree Included Angle Fine (600 Grit) Diamond Cone

Our 60 degree included angle diamond cones are the perfect way to grind down the interior lip of vessels or other open ended glass pieces. Available in Coarse-100 grit, Medium-220 grit, and Fine-600 grit, they can be used before the resin based smoothing cones for quickly removing more glass from thicker walled pieces and creating larger interior bevels.
