Description:
Brief Introduction of B-Series Diamond Core Bits
The B-Series diamond bits are cutting tools .They are widely be used for wire-line core drilling. They contain diamond segments bonded to a base material.
The Bits could be impregnated, they are single tube core drill bits.
They are widely applied in cutting non-ferrous materials.
Yaheng’s bits are using high quality diamond materials and also based on Yaheng’s exquisite technology.
 Features of B-Series Diamond Bits
 1. Wide hardness range. Yaheng could produce the bit hardness from 5 to 55°
2.  High drill speed.
3. Longer service life.
4. Competitive prices.
5. 15 years experience in manufacturing diamond core bits.
