Bihui Diamond Finger Bit, 20 mm M14

BIHUI diamond finger bit, 20 mm

The Bihui brand has not been working on the Ukrainian market that long. But it specialises in tools for tilers. One tool specific to professional tilers is the straight and tapered bit with diamonds applied by vacuum brazing. The bits are made for enlarging holes, for putting a small chamfer inside a hole, and for taking material off the tile edges. The quality of the vacuum brazing gives the bit a long working life. The bit mounts on an angle grinder. It works dry. Medium speed is preferable, it makes the bit last longer. But for speed you are allowed to work at the maximum 11000 rpm. The Bihui brand offers 2 straight bits, 10 and 20 mm, and 2 tapered bits
