Product Description

Coal drilling teeth diamond pick teeth PDC conical buttons PDC cutter

PDC buttons are essential components for modern drilling, typically available in two primary functional shapes to suit different geological requirements.

Flat Nose PDC Buttons

Flat nose PDC buttons are composed of diamond and carbide layers, sintered under specific high temperature and high pressure conditions. These super-hard composite materials are ideal for petroleum geologic drill bits, specifically designed for soft and upper strata drilling.

Ball Nose PDC Buttons

The ball nose series combines the high toughness of cemented carbide with the extreme wear resistance of diamond. Featuring optimized impact geometry and synthesized under constant high pressure, these buttons offer superior impact and wear resistance. They are perfectly suited for roller bits and mine submersible drills in hard or complex formations.

🚀

The Main Advantages

High wear resistance for extended operations.
Excellent high impact resistance for tough terrains.
High thermal stability under extreme friction.
Increased working life of PDC cutters (by more than 6 times).
Significant reduction in bit replacement frequency and labor intensity.

🏗️

Applications

Due to high performance, PDC cutters are widely utilized across various drilling industries:

Oil and gas PDC bits (Face, gauge, and backup cutters)

PDC bits for geothermal drilling

PDC bits for water well drilling

PDC bits for directional drilling

Frequently Asked Questions

Q1: What does PDC stand for?

PDC stands for Polycrystalline Diamond Cutters. They are made by combining synthetic diamond with a tungsten carbide substrate under high pressure and temperature.

Q2: What are the differences between Flat Nose and Ball Nose PDC buttons?

Flat nose buttons are generally used for petroleum geologic bits in soft strata, while ball nose buttons offer higher impact resistance for hard formations and roller bits.

Q3: How much longer do PDC cutters last compared to traditional materials?

PDC cutters can increase the working life of drilling bits by more than 6 times due to their extreme wear and impact resistance.

Q4: Are PDC cutters suitable for geothermal drilling?

Yes, PDC bits are highly effective for geothermal drilling, as well as oil, gas, water well, and directional drilling applications.

Q5: What makes these buttons thermally stable?

The sintering process under high temperature and catalytic methods ensures the diamond layer maintains its integrity even during high-friction drilling operations.

Q6: In what sizes are these PDC cutters available?

Common specifications include sizes such as 1916, 1913, 1613, 1610, 1313, and 1308 to fit various bit designs.
