This 152 mm RC TCI tricone bit is built for crews who measure progress in clean samples and steady footage rather than promises. The large insert teeth “bite” with a crisp, tactile snap, while the sealed bearing runs cool and quiet—less chatter at the rotary table, a steadier hum through the string. Reverse circulation pulls fines through the center, so cuttings leave the face fast and the cones don’t polish. On mixed benches—soft shale turning gritty without warning—the cutting structure stays engaged, pushing a consistent rate of penetration with fewer stalls. Picture your sampler tray: sharp-edged chips instead of slurry, colors that read true. That’s how decisions get faster on site, trips get fewer, and budgets hold.

Built for RC hydraulics. A generous center passage and balanced nozzles sweep fines before they glaze, keeping inserts sharp and torque stable.
Large-insert cutting structure. Chisel-profile inserts fracture friable lithology cleanly and resist micro-chipping in abrasive streaks, protecting ROP when the ground changes.
Quiet, cool bearings. The elastomer-sealed system retains premium grease under heat and load, which you’ll notice as a lower, steadier rotary sound and longer run hours.
Edge armor that pays back. Optional gauge and shirttail hardfacing defends OD and heel, preserving hole size and directional intent on longer pushes.
API-ready rig-up. The 3 1/2 API REG PIN connects fast across mixed fleets, reducing connection risk and change-out time.
Operator feedback you can feel. Cleaner returns and linear torque make it easier to dial in WOB and pumps by sound and feel, not trial and error.
Standards & Classification: IADC mapping and API thread compliance across fleets; documentation on request for QA/technical files.
Structure & Materials: TCI vs. steel tooth selection, sealed/journal/roller bearing options, and gauge/shirttail protection packages tailored to abrasion levels.
Operating Guidance: Starting windows for WOB/RPM, mud weight/viscosity hints under RC, and nozzle/center-return setup to control face cleaning and sample clarity.
Applications: Water well, oil & gas, HDD crossings, geothermal loops, and mineral exploration—each with typical lithology notes and starter parameters.
Customization: Center-hole diameter, nozzle layout, IADC fine-tuning, private labeling/marking, and packaging specs aligned to your depot workflows.
Quality & Compliance: Incoming material control, assembly tolerances, seal and lubricant temperature performance, and inspection records for audits.
Commercials: MOQ from 1 pc, wooden-case packaging, indicative lead times, Trade Assurance/escrow options, and after-sales technical onboarding.
A bit should lower total cost per meter, not just look good on spec sheets. This RC-first design keeps ROP high while protecting inserts and seals—fewer unplanned pulls, fewer regrinds of cuttings, and steadier decision-making from cleaner samples. For contractors scaling across regions, we align threads, protection packages, and operating windows to your rigs and rock so crews don’t relearn basics every site. You get clear documentation, responsive failure analysis, and selection support that shortens the ramp on new ground. In short: predictable footage, cleaner data, less noise—both in the returns and in your project plan.
Operational advantages at a glance
Reduced trips via longer bearing life and stable torque signature
Consistent sample quality under RC for faster on-site calls
Configurable protection to preserve gauge and reduce corrective reaming
API thread compatibility to simplify fleet logistics
Q1: Which formations fit this 152 mm RC TCI bit best?
Soft to medium formations (soft shale, limestone, sandstone) including abrasive interbeds. For very hard, massive quartzites, request a harder IADC option.
Q2: What startup parameters do you recommend?
Begin around 0.6–0.8 kN WOB and 70–90 r/min, then tune by torque stability and return clarity. Maintain mud properties that keep fines suspended under RC flow.
Q3: Can we customize features?
Yes—center-hole diameter, nozzle layout, IADC fine-tuning, and gauge/shirttail protection can be configured to your pumps and ground.
Q4: How does RC improve economics vs. conventional circulation?
By pulling cuttings through the center, face heat and regrinding drop; inserts stay sharper, seals last longer, footage between trips extends.
Q5: Threads and fleet compatibility?
Standard is 3 1/2 API REG PIN; alternatives are available to match your drill string and adapters.
