Review on 🧰 6-Inch Blade Scraper with 2-Foot Long Handle - CO-Z SDS-Max Chisel Bit for Efficient Tile Grout, Adhesive, Wallpaper, Thinset, Wood, Linoleum Flooring Removal - Rotary Hammer Drill Compatibility with SDS-Max Bits by Antonio Gonzalez

I bought this attachment to use with my 11 lb Makita jackhammer for medium to thin tile removal. I couldn't even get half of my job done and the racquet pins started vibrating. About every 2 minutes I had to pull them up. Eventually one fell out so I pulled them all out and replaced them with the four spares that came with it. I worked with the new bolts for about 5 more minutes, then they also started vibrating and falling out. A quick look at the bolts shows that the vibration of the chisel and drill bit is smoothing the threads of the bolts and they are no longer staying in, much less tightening. Very disappointed with the product and this purchase has thrown me back on my project. I recommend looking for a bit that doesn't have friction points (like screws) that can fail prematurely. The blade itself was ok but the product as a whole is not what I would recommend.
