QDL pitches custom ODEX bits over mass-produced drilling tools

QDL is promoting customized ODEX bit services as a more efficient option than mass-produced drilling tools for deep-well, foundation and overburden projects. The company says the approach improves penetration, reduces stuck-drill risk and better matches specific ground conditions across global drilling jobs.

Why it matters: - QDL is arguing that drilling efficiency depends more on tool-to-ground matching than on upfront purchase price. - In deep-well and overburden drilling, fewer trips, less clogging and lower stuck-drill risk can cut downtime, labor and fuel costs. - The company positions custom ODEX bits as a way to improve rate of penetration and project predictability in difficult formations.

What happened: - Putian Qideli Engineering Equipment Co., Ltd. promoted its custom ODEX bit supplier services as an alternative to mass-produced drilling tools. - The company published the comparison from Putian, China, on Sept. 18, 2026. - QDL said its customized approach is designed for deep-well drilling, water wells, geothermal work, piling and foundation engineering.

The details: - QDL says standardized tools are built for average conditions and can fail in loose overburden, boulder beds, backfill and fractured formations. - The company says those failures can include premature button fracture, body shearing, clogging, stuck drills and dropped components. - QDL says its customization process starts with drilling method, rock density, borehole diameter, operating air pressure and site conditions. - The company says its ODEX bit range runs from 90 mm to more than 500 mm. - QDL says it can match bit shanks to CIR, P, QD, HD, DHD, MISSION, QL, SD, NUMA, MACH and BR hammer models. - The company lists six overburden drilling systems: eccentric overburden drill system, 2-wing eccentric reaming bit, swing wing drill bit, 3-wing concentric casing system, ring bit concentric casing system and sliding block drill bit. - QDL says the eccentric overburden drill system opens on forward rotation and retracts on reverse rotation. - The company says the 2-wing eccentric reaming bit is aimed at loose, soft formations and low-pressure drilling at 0–30 meters. - QDL says the swing wing drill bit was first optimized for small rigs in the Russian water well market. - The company says the 3-wing concentric casing system works well in 0–40 meter soft strata or hard overburden and reduces the need for operator skill. - QDL says the ring bit concentric casing system is recommended for complex loose ground or deep wells beyond 50 meters. - The company says the sliding block drill bit is suited to continuous large-diameter foundation pile holes in shallow complex rock layers. - QDL says its bits use special alloy steel, deep carburizing heat treatment, custom flow ports and junk slots. - The company says those features help resist wear, remove cuttings and keep cutting edges cool. - QDL says its button socket process keeps abnormal button-dropping below 0.5% and bit fracture below 1%. - The company says clients can provide shank and casing dimensions, and QDL returns technical blueprints for fit verification. - QDL cites ISO9001 and SGS as part of its manufacturing framework. - The company says its Chile project used a ring bit concentric casing system to complete an 80-meter continuous casing run in loose soil and fractured rock. - QDL says it began manufacturing in 1993 and specialized overburden tool production in 2009. - The company says it is based in Putian, Fujian, and operates as a vertically integrated business with in-house production, quality control and export logistics. - QDL says annual export value exceeds $10 million. - The company says its repeat purchase rate is above 97% and product defect feedback is below 1%.

Between the lines: - QDL is framing customization as a response to the limits of one-size-fits-all industrial equipment. - The pitch also aims to reassure buyers that bespoke drilling tools can still fit international hammer standards and global procurement workflows. - The Chile case study is being used as proof that the customization model can solve real field problems, not just improve specifications on paper.

What's next: - QDL is directing buyers to its website for specialized drilling solutions, technical specifications and global case studies. - The company appears to be using field performance claims and international standards to strengthen export demand in water well, foundation and geothermal markets.

The bottom line: - QDL is betting that custom ODEX bits will win contracts by reducing drilling risk, extending tool life and improving jobsite efficiency compared with mass-produced alternatives.
