Daotian drill bits were made by metal bonds with proper hardness, which can quickly startup. With innovative suppression technology, our drill bits well closed formation, high strength holding, and longer life.

QUALITY- The quality of the drill bit is evaluated by the amount of chips generated on the face of the glass. Visual check is the only way of ascertaining quality.

BREAK IN TIME- Similar to a diamond wheel, drill bit like any diamond tool requires some time to break in, like produce relatively chip free glass.

FREQUENCY OF DRESSING- Lower the frequency of dressing to re-expose the diamond, better the drill bit.
