STEPPED DIAMOND PLATED CORE DRILL 2.35mm Shaft
These step from a 2.35mm shaft and taper to a narrow head allowing it to fit in most micromotor handpieces.
Diamond Core drills are used in a rotary tool such as a Dremel or can be used in a drill press for making small holes through stones. The holes can be used for hanging the stone by a cord, leather or jewellery findings.
It is always recommended to use a coolant (usually water) when working with these drill bits. This will help increase the life of the product and offer you a better value. It is also recommended that you wear eye protection such as safety glasses.
Do not force the drill bit, let the diamond do the cutting. Frequently take the drill bit out of the hole you are drilling and flush with water to remove the debris.
