Enter what you know about the hole — the application, the bit size, the formation, and the IADC code if you have one — and this tool assembles a starting specification: the standard API Regular connection for that bit size, a PDC-or-tricone starting call, and the IADC guidance to carry your bit design from one order to the next. It is a starting point the factory confirms, not a final specification. When it is ready, one button hands the whole thing to WhatsApp as a quote request, China-direct, CFR (Cost and Freight — the sea freight is in the price, and you insure locally) to your port.
This tool covers forgiving applications: oilfield onshore and workover, water-well, HDD and trenchless, and mining and exploration. Deepwater and directional wells run on integrated service contracts are not served — there is deliberately no option for them here, because that work needs a field engineer at the rig, not a specification assembled from a form.
The bit size to connection mapping is the same one published on our bit-to-connection chart, boundary zones and all. Where that chart shows a size can ship with either of two connections — the 4 to 4-1/2 inch band, the 9-1/2 to 9-7/8 inch band, and the 14-3/4 to 17-1/2 inch band — this tool shows both and tells you to confirm the pin against your bit sub, rather than guessing a single answer.
The bit-type and IADC guidance follows IADC bit codes explained. For a tricone, the formation gives a series — the IADC first digit — as a starting filter, hedged, with the second and third digits set later with the factory. For a PDC, the tool does not invent an IADC code: the fixed-cutter IADC class is rarely used in commerce, so a PDC is described by blade count, cutter size, and body type, which the factory sets from the size and your formation. Nothing the tool produces is final — it is the starting point a qualified factory confirms and quotes against, exactly as described on how we verify a bit factory.
