Diamond Plated Twist Drills
Diamond twist 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 finding.
Please Note: The shaft diameter on each drill bit is similar to its drilling diameter. They are not designed to fit a 2.35 collet. Tools such as the Dremel will require an adjustable check to hold the drill bit. Micro Motors and quick release handpiece will also not hold them.
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
