Wet Core Drill Bit Dry Core Drill Bit Core Drill Bit Adapter Core Drill Bit Extension Diamond Core Drill Bit Review: Worked Great - I wanted to make water fountains out of two pieces of sandstone. I needed to drill 1” holes 26” through the length of the stone. I bought two bits from two different manufacturers incase one did not work as well as another. For once, Blue works better than Red and as it turned out the HBKEEN performed the best. I used the other brand for only a short period of time due to the obvious performance differences. The HBKEEN cut faster and was easier to clean out. The sandstone packs inside the core bit and I found it easier to wash the waste out with a hand pump sprayer than to try to knock the waste out. The HBKEEN has teeth with an inside diameter smaller than inside diameter of the tube, so the core is easier to clean out. The other brand has an inside diameter which is close to the same, which makes clean out harder. Even with the HBKEEN, it needed to be cleaned out ever inch or so. The only drawback to the HBKEEN was that the threads for the adapter are recessed about 1/2 inch or so and my adapter would not engage the threads. Using a hacksaw, I cut about 1/2” off the end of the bit. I ground the end so that the shoulder would be square with the adapter. Then it worked fine. I bought extensions so I could drill the full 26” from one end for a straight hole. Review: Excellent diamond Core Drill Bit - Formidable diamond core drill requires water for cooling, easily passed through buried 8” concrete slab, allowing me to drive a steel pipe through the slab in order to secure it as the receptor for a double gate vertical center rod. Word to the wise: the correct drill adapter must be bought separately depending on the drill’s chuck. Also a regularly powered drill with side handle is preferable to battery powered gear especially to control for the bit locking up occasionally in the concrete. ## Features - DURABLE AND EFFICIENT CUTTING: Our wet diamond drill bits are built to last, engineered with premium diamond tips for excellent cutting capabilities.
