FAQ
You are more than welcome to return your item unless the product description states it is non returnable (this applies to face masks, thongs, socks and some lingerie – please refer to “Product Details” for more information).
Please do your best to try on, handle and repackage the items with care. Items must be returned in their original condition – unworn, undamaged, free of makeup, pet hairs, deodorant and perfume and have all original tags.
PDC bits use fixed polycrystalline diamond compact cutters to shear the formation, while tricone bits use three rotating cones equipped with steel teeth or tungsten carbide inserts to crush and break the formation.
PDC bits can provide high penetration rates and efficient drilling in suitable homogeneous formations. Tricone bits are often preferred where the ground is harder, fractured, interbedded or highly variable.
The right choice depends on the actual geology, drilling parameters and project requirements rather than formation hardness alone.
Yes. Drillnova can customize PDC bits according to HDD rig and project requirements, including bit diameter, blade configuration, PDC cutter size, connection and nozzle arrangement.
Send us your HDD rig model, required bit size, connection and formation information, and our team can recommend a suitable PDC bit configuration for your application.
Production lead time depends on the bit size, configuration and order quantity. Standard PDC bit configurations can typically be produced within 2–3 weeks, while customized designs may require additional time for drawing confirmation and production.
Drillnova ships PDC bits worldwide by air, express courier, sea or rail, depending on the destination, order size and delivery requirements. For urgent projects, we can also help evaluate the fastest available shipping option.
