Hard to Extremely Hard Rock Version

Product Highlights

Designed for granite, quartzite, and faulted hard rock, the Xinda Φ38 mm series uses a high-density coarse-grain carbide tip to deliver excellent wear and crack resistance.

A 42CrMo cold-forged body with graded hardness disperses impact loads effectively, while 95% braze saturation ensures reliable tip retention under extreme conditions—ideal for heavy-duty hard rock tunneling.

Performance Advantages

Designed for extremely hard rock formations (UCS ≈ 100–120 MPa), offering excellent impact and wear resistance;
Oversized carbide tip maintains sharp cutting edges and reduces wear under high loads;
High-strength steel body with precision brazing prevents tip loss and structural instability;
Extended service life, enabling continuous and efficient excavation in hard rock conditions.
