Thin Wall Diamond Core Drills

In the technical information tab on the product page you'll notice these indicate a shank size of 4.6mm which is too large for use in a Dremel. In a Dremel you will need an adjustable multi chuck then you can hold any drill bits with shank sizes of up to 3.2mm. One of the team will be in touch to let you know which of our diamond drills bits can be used in a Dremel.

You can also add a piece of masking tape to the drilling area, or start your rotary tool at an angle until the drill bit bites, then return to a vertical angle and carry on drilling.
