Introduction of tungsten steel diamond drill bits :
Our tungsten steel diamond drill bits for hard rock are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series. The matrix layer of the "DIYFIA" contains a uniform distribution of these crystal that are embedded in a powdered metal bond.
The matrix of our tungsten steel diamond drill bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action.
Feature of tungsten steel diamond drill bits
1. High wear resistance and impact-resistant toughness
2. Long drilling life
3. High drilling efficiency
4. Fast penetration rate
5. Labor intensity can be reduced
