That 146mm diameter gives you a solid 5.75-inch hole, and we forge it form high carbon steel so it holds up better than some cheaper alloys under heavy torque. 2. Most guys running water well rigs go with the 3-blade scraper shape because of that it clears cuttings fast in softer formations, and it's pretty much fine for coal mining too but don't push it through hard granite—it'll wear quicker than you'd like. 3. You'll get API threads as standard, but we can do Reg or custom if your tooling needs it, and the sandblasted suface treatment helps with corrosion during storage. 4. Lead time is usually 20 days or so for a standard order, and we can ship in wooden boxes or cartons depending on your preference—MOQ is just 1 piece so you can test one before committing to a bulk run. 5. We've had some buyers ask for blue or gold coloring, which is fine, but the color doesn't affect performnce any—it's basically cosmetic. 6. Anyway, we keep stock on the common sizes like 6-inch and 7.5-inch, but teh 146mm might need a quick production slot, so confirm availability when you're ready.
MOQ is just 1 piece, so you can order a single bit to test it out before committing to a larger batch.
Custom orders usually ship within 15-20 days after confirming thread specs and color. Standard sizes ship faster.
Yes, it's built to API standard and we can provide the relevant certs with the shipment.
You can choose API, Reg, or go fully customized. Just tell us your rig's thread type when ordering.
Each bit goes in a wooden box or carton to protect it during shipping. We can label or pack as you require.
