Komatsu RC Series (Rock Chisel) — Engineered for Extreme Penetration

Komatsu RC Series (Rock Chisel) — Engineered for Extreme Penetration

The Komatsu RC Series (Rock Chisel) is specifically engineered for extreme penetration in hard-packed ground, rock, and frost. The "RC" profile features a sharp, ribbed chisel point designed to fracture hard materials while maintaining structural integrity. Covering the full Komatsu range from the compact PC60 to the massive PC1250 mining excavator, these teeth are the premier choice for quarrying, mining, and heavy-duty trenching where standard teeth fail to penetrate.

1. Core Advantages

  • Superior Penetration: The sharp chisel-shaped tip significantly reduces the hydraulic breakout pressure required to fracture hard strata, improving digging speed and fuel efficiency.

  • Reinforced Ribbed Design: The central vertical rib adds structural strength to the tooth body, preventing catastrophic breakage under high-torque prying forces and ensuring even wear.

  • Premium Alloy Casting: Manufactured using advanced vacuum casting and specialized heat treatment to achieve a high Rockwell hardness rating while maintaining critical core impact toughness.

  • Exact OEM Interchangeability: Fully compatible with Komatsu standard adapters and side-pin locking systems, ensuring a precise fit for the LK and PC series.

3. Key Application Environments

  • Rock Excavation: Primary digging and tearing in limestone, shale, and heavily fractured rock formations.

  • Mining & Quarrying: High-impact loading cycles of shot rock, ore, and tough industrial aggregate.

  • Frost & Hardpan: Aggressive fracturing through frozen topsoil, permafrost, or highly compacted clay strata.

  • Trenching: Heavy-duty municipal utility work and pipe-laying operations in abrasive, rocky soil corridors.

4. Application Note & Selection Advisory

Technical Allocation Protocol:
• Penetration vs. Abrasion: The Rock Chisel (RC) Series is designed specifically for maximizing structural penetration. For extreme high-abrasion but lower-impact environments (such as loose abrasive sand or fine quartz gravel), please refer to our Heavy-Duty (HD) or Long-Life series to ensure optimal wear geometry match.
• Locking Retainers: High breakout forces can stress the locking hardware. Always replace the horizontal pin retainers during every G.E.T. system cycle to prevent accidental tooth loss in the pit.
