Non-leached Polycrystalline Diamond Inserts, PCD Cuttes For Rock Core Drill
PDC consists of two parts: polycrystalline diamond layer and tungsten carbide bas. It is a super hard product made by sintering super hard composite material under special high temperature and high pressure.
Features: Good wear-resistance, impact resistance and good thermal stability.
Application: it is suitable for making petroleum drill bits, coal mine drill bits and cutters.
Zzbetter can provide PDC with various specification. Our standard PDC product is of cylindrical form, other forms of these cutters can be made according to customers' specific requests. We can also provide leaching and polishing process according to your special requirements.

Design Target of D PDC Insert
ZZBetter D PDC inserts are mainly used mining picks and DTH hammers, which can be applied for drilling hard formations and abrasive formations.
ZZBetter can produce different types of Spherical Products, the specifications of D PDC inserts are from Φ5mm ~ Φ25mm, with shape of dome, Conical, Parabolic and Teeth.
Design Target of T PDC Cutters
1. TC PDC Cutter (Flat shaped, Comprehensive products)
2. TD PDC Cutter (Flat shaped , High Wear Resistance Products)
3. TP PDC Cutter (Spherical Products)
To meet different drilling requirements of PDC cutters, Zzbetter had developed the third generation TC and TD PDC Cutters in the year of 2014.
TC PDC Cutter: Compared with TRC PDC cutter(the second generation), TC PDC cutter has improved impact- resistance more than 1 time, and the wear-resistance of TC PDC cutter declines a little(less than 20%), thermal-stability significantly increases.
TD PDC Cutter: Compared with TRC PDC cutter(the second generation), TD PDC cutter has improved wear-resistance 40%, impact-resistance and thermal-stability significantly increase.
Zzbetter TP PDC cutters are mainly used in back-up row, inner cone, gauge row of PDC bits and Rock roller bits, which can be applied for drilling hard formations and extremely hard formations.
We can produce different types of Spherical Products, the specifications of TP PDC cutters are from Φ5mm~Φ25mm.
T PDC Cutters characters and recommendations
| Products | Characters | Recommendation |
| TC series | Excellent impact resistance and good wear resistance. TC is the products with balanced technical indexes, comprehensive performance excellent. | Recommended for use in complex geological condition of vertical well section. |
| TD series | Excellent wear resistance and good impact resistance. TD is the products with excellent wear resistance performance. | Recommended for use in high demand for grinding of horizontal well section. |
| TP series | Spherical products with excellent impact resistance and good wear resistance. | Recommended for the use of PDC in kick-off section with TC or TD. |
We have strict quality control system for PDC cutters, the following lab tests and analysis to make sure every piece of product are perfect when reaching to customers' hand:
