Review on Diamond Core 💎 Drill for Concrete- Toolgal by Bobby Frazier

I have years of experience drilling wells and 33 years as a plumber. I'm a plumber at a big academy and I'm fed up with constantly messing around in my shop to get rental junk as our shops don't need an annuity. On day one I used it alone to punch twenty-three 3" holes in 10" concrete in one day! There are too many bad experience reviewers here to call them all abusive drill bits, and different steel fills and bad welds in different batches are possible, but with all the bits I've ever bought, I've NEVER had the issues that many others had. Follow my advice and you shouldn't have any problems either. Tips from a knowledgeable person: 1- Connect the water hose to the machine. Do not use a spray gun unless there is another option. The hose plays an important role in preventing debris from entering the cut groove and also keeps the plug from getting stuck in the core, keeping it cooler and free from accumulated debris. drown him. The second you lose revs is the same second you slow down the rate it shrinks and risk burning the car. 3- Listen when others use your car. Again, listen to people who lean in too far and slow it down. 4- Before tightening a little, wrap a loop of solder between the threads and where the core will sit. This will make later removal of the bridle MUCH easier and almost effortless. You only need to tighten the drill bit by hand, rotating the core tightens it while cutting. You don't have to unscrew it to begin with, which makes it a bit difficult to remove later. my dentition, 4 inches from the bottom of the teeth. When I touch the tape I just take the chisel and stick it in the side. If you're going at least 4 inches and there's no rebar, you don't even need a hammer, just a light tap on one side and the other breaks it clean. One of the reasons cars get stuck is double friction. The concrete on the outside of the bit is much softer than the inside. A slight change in angle can dramatically increase this friction. If you break it at 4 inches or a little later, you'll retain high RPM and much faster shots with less effort. If you go too far beyond 4 inches you will likely blow off the bullet in the drill bit, rotating with the drill bit making further penetration almost impossible. 6- In and out. A little back. They will form a hardened ring of concrete around the drill. This will prevent you from easily removing it from the hole. Just be careful when using a hand drill that you don't come out all the way, otherwise you may get caught, and you may be surprised. 7- DO NOT hit the object hard with a hammer Anyone who has drilled a core knows that when a piece of concrete breaks off in the core, you hit the sides to pull the piece out. It's still true, but don't hit hard. You need lots of quick little soft hits. No hard hits. You will dent and warp it, which always makes it very difficult to use (even if you can't see it). If you use a hose connection and break it every 4 inches you will most likely never need to do this, but if you are using a spray gun you will probably ALWAYS need to move away from the auger. What actually pushes the cork out when tapped is the fact that smaller particles and dust fall out around the cork, allowing the cork to move more freely. Have fun drilling!
