Craft TC Drilling

This is a small range of hinge sinking machine bits that are usually used kitchen furniture manufacturers and fitters for producing the circular groove required to fit the circular hinges that are commonly used for cupboard and cabinet doors. They are designed to be used with pillar drill machines and all feature two wings and a centre point. Depending on which bit you go for, they are designed either to work exclusively with natural timbers or with melamine covered chipboard.
