Description
Overview
Bihui DMB10A and DMB20A diamond milling bits enlarge or refine holes after drilling. Choose the 10 mm or 20 mm straight mill according to the opening and the amount of clearance available; both are medium-grit tools with a 5/8"-11 threaded connection.
Features
- Medium-grit diamond surface for hole refinement.
- Two straight-bit diameter choices.
- Wet or dry operation.

Applications
Use to enlarge or refine an already-drilled opening in tile, stone or concrete. The bits are also described for finishing rough edges on glass, ceramic and porcelain; select the bit diameter and equipment to suit the actual material.
Selection and Use
- Choose 10 mm or 20 mm in the selector; these are individual size options.
- The A-suffix parts here use 5/8"-11 threads. An M14 version described elsewhere in the product family is not an additional thread on the same bit.
- Begin with a drilled opening rather than treating the milling bit as an ordinary hole-starting drill.
