Re: Re: drilling jasper?
Yes, I did use water. Things went fine initially but quickly slowed and the diamond was gone by before going through .... I had bought 6 cores from Rio Grande .... did not take long to wear them down to just metal .... maybe I was being too impatient in expecting it should drill easily as it did for the first 1/16 inch?
