Diamondsharp utilizes state of the art laser welding for superior bonding strength able to withstand heat generated from dry drilling. Sometimes referred to as hole saws, these drills may either be used with a non-percussion drill or hand-held grinder equipped with 5/8 inch -11 threads for direct connection. Electric hand drills equipped with a 3/8-inch 3-jaw chuck require the No, 101 adapter listed below to mount any of the drills shown in the picture.
