Drilling Tools and Equipment Solutions

Efficient drilling operations demand high-performance tools that can withstand extreme downhole conditions while delivering consistent results. Yantai Sanmon Machinery Equipments Co., Ltd. offers a comprehensive drilling tools portfolio designed to help operators reduce non-productive time, improve rate of penetration, and achieve total depth safely and economically.

1 PDC and Diamond Drill Bits

Our polycrystalline diamond compact (PDC) drill bits represent the cutting edge of drilling technology, utilizing advanced cutter technology and optimized hydraulic designs for maximum drilling efficiency. Available in sizes from 6" to 17-1/2" with various blade counts (4, 5, 6, and 8 blades), each bit is engineered for specific formation types.

The cutter layout on SANMON PDC Bits is designed using proprietary force-balancing algorithms that ensure even wear distribution and minimize vibration. Premium-grade PDC cutters with enhanced thermal stability and impact resistance deliver extended bit life in abrasive and interbedded formations. Matrix body construction with reinforced blade geometries provides the structural integrity required for high weight-on-bit applications.

For especially hard and abrasive formations, we also supply natural Diamond Bits and thermally stable polycrystalline (TSP) bits that offer superior durability when conventional PDC technology reaches its operational limits.

2 Drill Pipes and Tubulars

SANMON supplies API 5DP certified drill pipes manufactured from high-strength grades including E-75, X-95, G-105, and S-135. Our drill pipe inventory covers sizes from 2-3/8" through 6-5/8" with standard and heavy-weight configurations, offering various tool joint options (NC26 through NC50 and 5-1/2 FH).

Each joint undergoes rigorous inspection including ultrasonic testing of the tube body, magnetic particle inspection of tool joints, and dimensional verification. Internal plastic coating options are available for corrosion protection in drilling fluid service. Heavy-weight drill pipe (HWDP) with spiral and non-spiral configurations provides the transition stiffness required for directional drilling applications.

3 Fishing Tools

When downhole equipment becomes stuck or separated, rapid recovery is essential to minimize costly downtime. Our API 7-1 compliant fishing tools portfolio includes overshots, spears, junk mills, taper taps, and safety joints designed for efficient retrieval operations.

The Series 70 short catch overshot provides reliable external engagement of fish necks in congested wellbore conditions. Our junk mills are manufactured with crushed tungsten carbide inserts for aggressive cutting action on steel and hard debris. Each fishing tool is supplied with complete dimensional data and operational guidelines to ensure compatibility with your specific fishing assembly.

4 Drilling Accessories and Support Equipment

Completing the drilling package, we supply API Model F Baker-style drill pipe float valves, drill pipe centralizers, Stabilizers, and cross-over subs. Our drill pipe float valves feature flapper-type and plunger-type designs with reliable sealing performance to prevent backflow during tripping operations.

SANMON's commitment to drilling performance extends beyond product supply. Our team provides technical consultation on bit selection, drilling parameter optimization, and fishing procedure planning to help your operations team achieve superior results.
