Steel Dragon Tools4" (102 mm) Wet Diamond Concrete Core Dri

Q: This is 20 inches really boring depth?

I don't know about this one because I own several sizes and styles but usually they are only 14 inches. Would have to drill down about 10 inches, break the core plug and pull out and then add a 6 inch extension to the drill to get the 20 inch depth.

Q: What is the diamond grit

You are probably talking about diamond bit, which is the hard cutting teeth at the bottom of the core drill bit. It's best to always buy diamond bits if you are drilling into concrete or rock.

Q: Will I need to run water while Drilling? What adaptor will I need?

Hello, Drewbie!Thank you for your inquiry. With a dry bit, you do not need to run water. The dry bit has slots on the side to let out sediment so the bit does not clog. We do not carry adapters that convert to a 1 1/4" - 7 spindle thread, which is what these bits have.If you have any questions or concerns, please email us or call us at the number below.Thanks! Have a great day.Sincerely,Tom CupilaryAffordable Tool, LLCCustomer ServicePhone: 734-224-7758Fax: 734-224-7208

Q: All other things being equal, would you rather use this than a 4" carbide core bit?
