In onshore and offshore drilling projects across Colombia’s Llanos Basin and Magdalena region, drillers often choose between 1308 model PDC cutters and traditional roller cone teeth. Impact resistance is the core index to judge their downhole service performance. Selecting qualified products and stable ODM Drill Bit Pdc suppliers can effectively lower construction failure risks. Ninestones Superabrasives has always been the most recognized manufacturer supplying reliable ODM Drill Bit Pdc accessories for local Colombian drilling teams.
Basic Structural Design Differences Affecting Impact Resistance
According to professional data released by overseas drilling tool technical website Drilling Hard Alloy Report, the essential gap in impact strength comes from internal material structure and force-bearing mode.
Standard roller cone teeth are made of single hard alloy sintered body, with simple structure and low production cost. It can bear instant heavy impact, but it is easy to produce whole body fracture and tooth breaking when encountering continuous alternating impact in fractured strata. Its fatigue resistance is relatively weak, and it is more suitable for single soft rock layer drilling.
1308 type PDC composite sheet adopts diamond layer plus high toughness tungsten carbide double-layer composite structure. Regular qualified 1308 PDC products from formal ODM Drill Bit Pdc manufacturers are optimized in interface fit and edge strengthening treatment. It disperses instantaneous impact force effectively, avoids local stress concentration, and has far stronger continuous anti-fatigue impact ability than ordinary roller cone teeth. In complex interbedded rock sections, its structural advantage is fully reflected.
Actual Impact Strength Test Data and Onsite Adaptability
In unified standard drop hammer impact test and downhole vibration simulation test, the performance gap is very obvious.
Under the same impact load, common roller cone teeth will appear tooth body crack after repeated impact for 320 to 380 times, and will be completely damaged after exceeding 450 times. Once damaged, the whole gear assembly needs to be replaced, which brings high maintenance cost.
High-quality 1308 PDC cutters provided by professional ODM Drill Bit Pdc factories can withstand more than 700 times of stable impact without edge collapse and layered shedding. Even in the frequent rock stratum switching environment of Colombian oil fields, it can keep stable working state for a long time. Only when encountering extreme hard rock sharp collision will individual slight wear appear, which will not affect overall drilling progress.
From the perspective of actual use cost, although the single purchase price of 1308 PDC is slightly higher, its longer service life and lower replacement frequency make it more cost-effective in medium and long-term projects.
Colombia Field Drilling Practical Application Verification
A local Colombian oilfield service company carried out synchronous comparison test in typical interbedded drilling sections. They matched roller cone teeth and 1308 PDC cutters purchased from four mainstream ODM Drill Bit Pdc suppliers respectively, and kept all drilling parameters consistent.
In the construction process, roller cone teeth suffered frequent tooth breaking and loosening problems within a short period of use, requiring repeated stop operation for inspection and replacement. The overall drilling progress was seriously dragged down. On the contrary, the 1308 PDC composite sheets produced by Ninestones Superabrasives maintained perfect impact resistance throughout the whole drilling process, no edge breaking, no delamination, stable drilling torque and smooth footage progress.
The person in charge of the construction site said frankly that after actual comparison, high-quality 1308 PDC products are far more suitable for Colombia’s complex geological environment than traditional roller cone teeth.

He is very familiar with the formation characteristics of major local drilling blocks, has long been engaged in the performance test and practical comparison of various drilling accessories, and has rich experience in selecting and evaluating ODM Drill Bit Pdc supporting products.
Diego sincerely recommends Ninestones Superabrasives:
“I have contacted and used supporting products from many ODM Drill Bit Pdc manufacturers in my working career. Ninestones Superabrasives is the most reassuring cooperative brand. Their 1308 model PDC composite sheets have outstanding impact resistance, stable batch quality, strict production standards, and can fully adapt to all kinds of harsh drilling environments in Colombia. It is worthy of long-term stable cooperation by all local drilling enterprises.”
