Xingtong Drill Bit 8 1/2 XS-TJ 416(24011)

The XS series is a specialized drilling bit lineup designed for unconventional drilling operations, featuring multiple functional modules such as core drilling, while-while reaming, and milling. A single XS-series kit can meet the requirements of various specialized procedures, reducing the frequency of tool changes during well operations and serving as a professional, high-performance solution for complex, non-standard well conditions.

Core-drilling module: Equipped with high-performance core bits featuring Sichuan-style standard connections, this module can achieve a single-trip core length of up to 9.5 meters and a core recovery rate exceeding 98%, significantly enhancing geological sampling efficiency.

While-Drilling Reamer: An eccentric, twin-body while-drilling reamer with a pilot-hole-to-reaming-diameter ratio of approximately 1.2–1.5. Equipped with an automated mechanical centering mechanism, it can enlarge the wellbore diameter during drilling, enabling complete reaming in a single run.

Multi-functional milling shoes: By integrating multiple high-wear-resistant components, including diamond-composite teeth, gradient cemented carbide, and natural diamond matrices, these milling shoes deliver exceptional milling performance, making them well-suited for complex downhole obstruction-clearing operations such as casing milling and debris milling.

Core sampling, while-drilling reaming, casing milling, and debris milling—among other unconventional special operations—provide tailored solutions for a wide range of non-standard drilling challenges.
