  • Product Description

Features & Benefits

  • Advanced ST58 Thread Profile: The ST58 thread offers a significant advantage over conventional T-threads, providing a more rigid connection, better energy transmission, and superior resistance to jamming, especially in deep hole applications.

  • Extended Thread Life: The modern rope thread design of the ST58 interface results in less wear and tear on both the bit and the drill rods, leading to a longer overall service life for your entire drill string and reducing consumable costs.

  • Optimized for Modern Rigs: Engineered to take full advantage of the power and advanced features of modern hydraulic drifters, the ST58 system allows for higher penetration rates and greater drilling precision.

  • High-Productivity Design: Combines the efficient 89mm drilling diameter with the superior ST58 thread to create a tool that delivers unmatched performance in demanding production benching environments.

Recommended Applications

  • High-Efficiency Bench Drilling: The primary application. Ideal for quarries and mines equipped with modern, powerful drill rigs, seeking to minimize drilling time and maximize operational uptime.

  • Deep Hole and Production Drilling: The ST58 thread's stability makes this bit an exceptional choice for deep production holes where straightness and easy uncoupling are critical.

  • Demanding Ground Conditions: The robust thread design provides extra security and performance when drilling in complex or fractured rock formations.
