Why Your HDD PDC Bit Performs Poorly: The Impact of Blade Count, Cutter Size & Back Rake
Blade count, cutter size, and back rake are the three key factors that determine HDD PDC bit performance:
More blades = higher stability, lower penetration rate
Larger cutters = higher aggressiveness, faster wear
Greater back rake = stronger durability, lower cutting efficiency
The optimal combination depends on formation hardness and drilling conditions.

Core Barrel Drilling Fails in Hard Rock: Causes, Fixes & Proven Solutions
Core barrel drilling fails in hard rock mainly due to incorrect tool selection, mismatched cutting teeth, insufficient torque, and poor drilling parameters. To improve performance, contractors must optimize the core barrel design, select the right teeth, and match machine power with rock strength.
How to Choose the Right Core Barrel for Different Rock Conditions
Choosing the right rock core barrel is critical for achieving high efficiency, low wear, and stable performance in hard rock drilling projects. Many contractors struggle with slow penetration, excessive tool wear, or even tool failure—often due to incorrect tool selection.
As one of the most essential Rotary Drilling Tools, the core barrel plays a key role in bored pile construction, especially in challenging ground conditions.
