Review on Raizi Mortar Raking Diamond Bit For Mortar Removal (5/16 Inch X 1 Inch) by Byron Howell

This product fit well on my grinder and had a convenient flat edged section for loosening with a wrench. It cut through mortar well. I used it to grind out the vertical brick joints. However, it took very little time for the bit to dull. Within at most a few minutes, I was already having to put my weight into the tool for it to perform well. I know that some mortars are harder than others, so it’s possible that the mortar in my home was hard. Regardless, I would have expected this to last longer.I would use this again, but not for the price. If it cost 1/3 the price, I wouldn’t mind using for another project.Picture shows the first one I used and how far worn down the but got compared to a new one.
