Review on 💎 Enhancing Precision: LOT Pcs Diamond Hole Drill for Flawless Cutting by Jason Taylor

I bought this set to drill concrete and porcelain stoneware. I needed different sizes so I could drill the right holes for different valves and controls when remodeling my master bathroom. They look pretty cheap but they did a fantastic job. The main thing is that they are well cooled with water when drilling holes. You don't need a special drill bit or extra parts, everything fits snugly in the drill chuck and works perfectly. Major hardware stores sell a similar product for about half the price and comes with just a nozzle and a 'cup' that you attach to the drill site so you can fill it with water to keep it cool. You don't actually need a mug as there are several ways to achieve the same result without a mug, e.g. B. making a ring out of plumbing and gluing it to the surface you are drilling into and then filling it with water. I poured a small amount of water onto the work area every 5-10 seconds until the cut was complete. You only need to use moderate pressure to get a nice clean cut. My only caveat: be careful which side you start on. If you cut the tile from the bottom up you will chip it. I gave the bit a slight tilt as I got to the end point when drilling from the bottom so one side started cutting through the top. I then flipped the tile over and used the top cut as a pilot drill to the bottom of the tile for an extremely precise, splinter-free cut.
