Features of Impregnated diamond bit
1. Carefully selected grades of high quality synthetic diamond which distributed in the depth of bit's matrix series

2. The matrix layer of the crown contians a uniform distribution of these crystal that are embedded in powdered metal bond.

3. Designed to expose new diamonds to the bits' cutting face as wear occurs.

4. Fast penetration rate is maintained as a result of this action.

5. Optimum diamond size, concentration and matrix type are dependent on the hardness and abrasiveness of rock formation.

6. Impregnateion Depth: 4/7/9/10/12/13/16/24mm or based on consumers' need
