Specializing in soft to medium-hard formations, our IADC 537G tricone bit from China combines ductile iron cones with staggered TCI teeth (10mm height) for efficient cutting in clay and siltstone. The sealed roller bearing system with self-lubricating journals reduces maintenance by 30%, while the concave bit face minimizes cuttings balling in sticky shale. With a 500kN WOB rating and 200 RPM tolerance, it’s suitable for shallow gas wells, water well construction, and offshore foundation drilling.
Custom nozzle configurations, ISO 9001-certified quality, and dedicated logistics for oversized bit delivery to global sites.

The 22'' (558.8mm) IADC 537G TCI tricone bit is optimized for soft to medium-hard formation drilling, featuring three ductile iron cones with tungsten carbide inserts (10mm height) in a staggered pattern. The bit incorporates a sealed roller bearing system with double-row ball bearings, capable of handling WOB up to 500kN and RPM up to 200. Its 20° cone angle and 8-blade design enhance cutting efficiency in clay, siltstone, and low-UCS sandstone, compliant with IADC 537G specifications for general-purpose applications. The concave bit face design reduces cuttings balling in sticky formations, supported by four 20mm nozzles for high-volume mud flow.
15° tip angle on conical teeth maximizes chip formation in unconsolidated clays (UCS <50MPa), achieving ROP up to 40m/hour in Mississippi Lime
Lightweight aluminum alloy cones (30% weight reduction) reduce starting torque by 20%, enabling easy engagement in low-WOB scenarios
Staggered tooth spacing (15mm) minimizes regrinding needs, with field data showing 30% longer tooth life in silty sandstone
Polyurethane seals with fabric reinforcement resist swelling in oil-based mud (OBM) with high aromatic content, passing 100-hour immersion test (ASTM D471)
Self-lubricating journal bearings (graphite-impregnated bronze) require no pre-drilling maintenance, reducing rig floor preparation time by 30 minutes
0.15mm bearing clearance accommodates thermal expansion in high-temperature wells (150°C), preventing seize-up during tripping
5mm-deep helical grooves on gauge pads disrupt mud cake formation, reducing differential sticking incidents by 40% in shale intervals
Concave bit face (radius 1.2m) improves cuttings flow velocity by 20% at the bit face, as measured by high-speed photography in lab tests
Optional nozzle configurations (jet: 16/18/20mm; impact: 12/14mm) allow customization for different mud types and flow rates
Shallow gas well drilling in alluvial plains (e.g., Texas Gulf Coast) with high clay content
Water well construction in loose Quaternary sediments requiring 1% diameter tolerance
Foundation drilling for offshore platforms in sandy seabeds with high tidal currents
Coalbed methane extraction in soft coal formations (Vickers hardness <50HV)
Nozzle Retaining Ring: Stainless steel clip (316SS) with anti-backout threads, tested to 10g vibration resistance (IEC 60068-2-6)
Cone Wear Gauge: Dial indicator (0.001mm resolution) with magnetic base, enabling precise measurement of cone penetration after each run
Bit Storage Rack: Heavy-duty steel rack (load capacity 2000kg) with adjustable dividers, compliant with OSHA 1910.176 storage standards
Formation-Specific Design: 5-point geometry optimization including tooth height, spacing, and angle based on client-provided core analysis (e.g., Atterberg limits for clays)
Quality Control: 20-stage inspection process including dye penetrant testing for cracks, torque testing (500-1000 ft-lb), and rotational balance checks
Logistics Network: Dedicated flatbed transport for oversized bits, with crating compliant with IMO IMDG Code for international shipments
Warranty Coverage: 1-year warranty against manufacturing defects, including free bearing replacement for premature failure (excluding wear and tear)
