Every single bit gets presure-tested at 25 bar minimum before it leaves the floor—we've had too many field failures with subpar inserts to skip that step, and the YK05/T6 carbide holds up better than the standard T6 in thermal cycling, which is basically what happens during deep hole drilling.
The thermal insert process means the ballistic or dome buttons stay locked in even when face gets hammered into granite—concave or convex face geometry is your choice, but most buyers go with flat for general well drilling because it gives a flatter wear pattern, roughly 15-20% longer life between dressings.
Batch consistency is tight enough that our company can send you COAs from the last three within 24 hours—if you're running a multi-rig operation, you'll appreciate not having to retest every pallet for hardness variation, which we've seen cause premature button loss in cheaper bits.
Also, the DHD350-140mm 5inch model is actually better suited for high air pressure hammers than those low-pressure CIR series jobs—don't try to run this on a 7 bar compressor unless you like slow penetration and stuck strings, it's just a fact of the geometry.
Retest policy is straightforward: we'll take back any bit that fails within the first 50 meters of drilling if you send us a piece of the broken insert and teh originial COA—usually 2-4 weeks turnaround, but confirm lead time if you're in a rush and need a replacement shipped same day.
MOQ is typically 10 units or so for custom face profiles like convex, but stock bits with flat face and dome buttons ship within a week—packaing is standard cardboard with foam inserts, nothing fancy, but it keeps the carbide form chipping in transit.
Our MOQ is typically 10 pieces, but we can negotiate for smaller trial orders if you're testing the bits for a new project.
Yes, we're ISO9001 certified, and we can supply material certificates and inspection reports with each shipment.
Absolutely—you can mix ballistic or dome buttons with flat, concave, or convex face designs. Just specify your combo when ordering.
Standard lead time is around 15–20 working days after confirmation, depending on the customization complexity and order size.
Store them in a dry, ventilated area away from moisture and extreme temps—ideally in their original packaging to protect the carbide inserts.
