We've been shipping these cutters to coal mining operations for years now, and the key differentiator is how well they hold up under repeated impact loads—the ≥30 J/cm² impact resistnce isn't just a spec sheet number, it translates to noticeably fewer bit changes in hard rock intervals, and the working temperature up to 750°C means you're not cooking the diamond layer when friction heats up. 2. 8mm to 19mm diameters cover most standdard bits, but if you need a custom geometry for a reaming tool or hole opener, we can adjust diamond layer thickness form 0.5mm to 2.0mm (usually takes 2-3 weeks for a new run). 3. Most of the guys running horizontal wells go with the 16mm or 19mm for back cone protection because they get better wear balance, and the suface finish at Ra ≤0.2μm helps with chip flow in sticky formations. But it's actually not the best pick for very soft topsoil sections where you'd burn through the diamond layer faster—a standard tungsten carbide insert does fine there. 4. We've got about 300 units in stock for common sizes like 13mm and 16mm, but MOQ on custom runs is 50 pieces or so—HPLC purity isn't a thing here obviously, but COA and performance data accompany every batch per API specs. 5. Price fluctuates with raw tungsten costs, though lately it's been pretty stable, and our company can typically match polycrystalline diamond compacts to your specific formation hardness once you send the rock sample.
Our standard range starts at 8mm, but we can go down to custom sizes below that. Just send us your exact requirements, and we'll work out the geometry and diamond layer for smaller diameters.
Yes, we can supply API-compliant quality documentation, including impact resistance and compressive strength test reports. Just let us know what format you need when placing the order.
Custom diamond layer thicknesses like 1.5mm usually add about 2-3 weeks to production. Standard sizes ship faster, but we'll give you a firm timeline once we confirm the specs.
Yes, they're designed for soft to extremely hard rock, and the diamond layer holds up to 700°C in air. The tungsten carbide substrate handles the thermal stress, so you're good for high-temperature drilling.
For custom sizes like 15mm, our MOQ is typically 50 pieces per order. If you need fewer, we can discuss pricing, but 50 is the standard to keep setup costs reasonable.
