A reliable casing shoe is your first line of defense against borehole collapse. Our diamond impregnated casing shoes undergo a specialized high-pressure manufacturing process to ensure diamonds are evenly distributed throughout the entire cutting crown. This guarantees consistent matrix wear and dependable performance. Designed to fit standard W-series casing threads, these shoes help drilling crews isolate problematic upper layers and transition to core drilling smoothly.
Casing Shoe Size & Compatibility Guide
We manufacture standard sizes fully interchangeable with global exploration equipment parameters:
| Casing Size | Shoe Outer Diameter (OD) | Shoe Inner Diameter (ID) | Matches Core Barrel Size |
| BW Casing Shoe | 73.0mm | 60.3mm | Pairs with BQ Drilling Tools |
| NW Casing Shoe | 88.9mm | 76.2mm | Pairs with NQ Drilling Tools |
| HW Casing Shoe | 114.3mm | 99.2mm | Pairs with HQ Drilling Tools |
| PW Casing Shoe | 139.7mm | 123.8mm | Pairs with PQ Drilling Tools |
Note: Custom heavy-duty walls and specialized face profiles are available for deep-hole or extreme-torque applications.
Technical Matrix & Face Profile Options
To adapt to different overburden geology, we offer multiple cutting face designs:
Flat Face Profile: The industry standard, offering excellent durability and balanced performance in most gravel and soil layers.
V-Ring / Corrugated Profile: Provides faster initial penetration rates in harder consolidated boulders and rock layers.
Heavy-Duty Hardfacing: Reinforced with tungsten carbide pins on the inside and outside diameters to maintain strict gauge tolerances over long casing runs.
Ordering Information
To help us quote the exact specification for your rig fleet, please provide:
Casing Size: (e.g., BW, NW, HW, PW / HWT).
Thread Connection: Standard universal casing thread or premium heavy-duty threads.
Formation Details: Let our engineers know if you are drilling through soft soil, loose gravel, or hard boulders so we can optimize the matrix hardness.
