Product Q&A

Q:Are your drill bits compatible with mainstream drilling rigs?

Yes. All our drill bits comply with Spec 7-1 industry standards, compatible with most mainstream rig models (e.g., Schlumberger, Halliburton) and can be directly assembled without additional adjustments.

Q:How to choose the right drill bit size and type?

It depends on 3 key factors: drilling depth (shallow/medium/deep wells), formation type (abrasive/soft-hard alternating/hard rock), and rig specifications. We can recommend the most suitable model based on your specific project parameters.

Q:What types of oil drill bits do you supply?

We mainly supply PDC drill bits (including 6-wing, 7-wing, 8-wing models), tricone drill bits, core drill bits, and scraper drill bits, suitable for onshore and offshore oil & gas drilling.

Q:What should we pay attention to during drill bit use?

Avoid excessive drilling pressure and speed; keep the drilling fluid clean to ensure effective cooling and chip removal; check the bit regularly for wear or damage to avoid jamming or bit breakage.

Q:What shipping methods do you support?

By express (DHL/FedEx/UPS, 3-7 days), by air (5-10 days), by sea (20-35 days). We will choose the most cost-effective way by your delivery address and urgency.
