Hello! Shandong Xinruishanhe Engineering Equipment Co., Ltd., welcomes your visit!
4-Hole Gauge Scraper
Cutting tools (including face scrapers, drag bits, and teeth) serve as the primary excavation force for shield tunneling. Forged from premium 42CrMo alloy steel, the tool matrix provides unyielding structural stability under extreme torque. Cutting edges are precision-brazed with high-grade tungsten carbide (HRA 86+), offering an optimized balance of impact toughness and abrasion resistance. Integrated with proprietary hardfacing overlays to prevent premature matrix recession, these tools are engineered for high advance rates and extended drive lengths in sand, clay, and weathered rock.
