Description of π Diamond Concrete Grinding and Shaping with Glitter
Made with high quality GE Superabrasive diamond, this bit will grind faster, last longer and cost you less than any comparable tool. Use on a regular (not impact) drill for grinding or shaping mortar, tile, granite, marble or any similar material. 4 5/8" long X 1/4" shank for use with variable speed die grinders or drills. Allow the bit to do the work and don't press to hard to prevent bending. Small 1/4" diameter prevents over-cutting into adjacent material.
