DTH bit
Jessif Rock Drill Co., Ltd. produces DTH bits constructed from a premium nickel‑alloy steel known as 23CrNi3MoA and equipped with YK05 tungsten carbide inserts, a combination that delivers high durability and wear resistance. The manufacturing process includes a hot‑insertion technique for the carbide buttons and a fully CNC‑controlled machining sequence that ensures dimensional consistency across each batch. Military‑grade heat‑treatment standards are applied to achieve a uniform hardness profile, and the bits are engineered for rapid penetration and effective hole cleaning.
In the rock‑drilling market, nickel‑alloy steel of the 23CrNi3MoA grade is regarded as a high‑performance material, offering tensile strengths above 1 200 MPa and good toughness in abrasive conditions. The YK05 carbide inserts provide a cutting edge comparable to internationally recognised T6 brands, enhancing wear life in hard‑rock applications. Typical DTH bits of this class are supplied in shank diameters ranging from 57 mm to 660 mm, covering low to high air‑pressure rigs, and are compatible with major brands such as Atlas Copco, Ingersoll‑Rand and Mission.
These bits are targeted at mining contractors, geothermal drilling firms and water‑well operators who require reliable performance in varied geological settings. The listing does not state a specific minimum order quantity, lead time or price, so buyers should request those details directly from Jessif Rock Drill. Common payment methods in the sector include T/T and L/C, but confirmation with the supplier is essential before finalising any purchase.

Sourcing DTH bit from Jessif Rock Drill Co., Ltd. - China Import Guide
Before ordering, confirm the 23CrNi3MoA alloy composition, YK05 carbide grade and the military‑grade heat‑treatment parameters. Request material test reports, hardness certificates and dimensional drawings to ensure the bit matches your rig’s shank size and performance requirements. Verify that the supplier can provide ISO or other quality certificates as part of the documentation package.
When planning shipment, ask the supplier which Incoterms they can offer, such as FOB Changsha or CIF Shanghai, and clarify the expected lead time once the order quantity is finalised. Typical payment methods include T/T and L/C; negotiate terms that align with your financing arrangements and request a pro‑forma invoice before payment. Ensure that the wooden crate packaging is suitable for your freight forwarder and that palletisation meets your handling standards.
Arrange a third‑party inspection before the bits leave the factory to check hardness, dimensional accuracy and the integrity of the carbide inserts. Request a pre‑shipment test report covering these parameters, as well as copies of any ISO or SGS certificates mentioned. Upon arrival, inspect the crates for damage, verify that all documentation accompanies the shipment, and confirm that the received bits conform to the agreed specifications before acceptance.
