About Jessin Rock Drill Co., Ltd. - Drilling Machines & Tools Supplier in China

China‑based Jessin Rock Drill Co., Ltd. lists ten active product lines, all centered on drilling equipment and related accessories. The catalogue includes PDC bits, DTH bits, DTH hammers, extension rods, MF drill rods, Atlas Copco spare parts, a shank adapter, a Boomer 281 spare part, drifter spare parts and a grinding cup, each falling under the broader HS chapters for drilling machinery and tool accessories (typically HS 8467‑8469). The supplier is classified as an imported, harbor‑tier vendor, indicating it sources its inventory for international buyers rather than manufacturing in‑house. Its product focus spans both agricultural drilling applications and general industrial drilling machines, reflecting the dual top categories identified in the data. The listing does not provide specific certifications, so buyers should verify any required compliance independently.

Product Range and Specialties of Jessin Rock Drill Co., Ltd.

The current catalogue covers a spectrum of rotary and percussion drilling components. PDC (polycrystalline diamond compact) bits are offered for hard‑rock applications, while DTH (down‑the‑hole) bits and hammers serve medium‑depth drilling in mining and construction. Extension rods and MF drill rods provide modular lengthening for drill strings, and the grinding cup is used for surface preparation of drill bits. Atlas Copco spare parts, including shank adapters and specific model components such as the Boomer 281 and drifter parts, cater to OEM maintenance needs. In the drilling tools industry, PDC bits are commonly graded by cutter size (e.g., 8 mm‑30 mm) and wear resistance, DTH hammers are rated by impact energy (typically 2‑12 kJ) and pneumatic or hydraulic drive, and rods are defined by diameter (30 mm‑76 mm) and tensile strength (often > 1000 MPa).

Trade and Export Information - Jessin Rock Drill Co., Ltd.

China is a leading exporter of drilling equipment, with major markets in Southeast Asia, the Middle East, Africa and South America where mining and infrastructure projects drive demand. HS chapters 8467‑8469 cover drill bits, hammers and spare parts, and shipments are frequently packed in wooden crates or steel containers sized for 20‑foot or 40‑foot units. Buyers usually request certificates of conformity to ISO 9001 or ISO 14001, and for safety‑critical components, CE marking or equivalent national approvals are common. Typical Incoterms for these heavy tools are FOB Shanghai or CIF destination ports, allowing buyers to manage inland transport. Exporters from China often provide mill test reports, material certificates and performance test data to satisfy importer compliance in target regions.

Sourcing from Jessin Rock Drill Co., Ltd. - Buyer Guidance

When sourcing drilling components from Jessin Rock Drill Co., Ltd., request detailed product datasheets that specify cutter grade, impact energy, rod diameter and tensile ratings. Verify mill test reports and, where applicable, ISO or CE certification copies before confirming orders. Samples of PDC bits or DTH hammers should be evaluated for wear resistance and impact consistency, and buyers should ask for third‑party inspection reports such as SGS or BV. Confirm packaging dimensions and weight to plan container loading, and clarify the preferred Incoterm to align with logistics responsibilities.

What types of drilling bits does Jessin Rock Drill Co., Ltd. supply?

The supplier lists PDC bits and DTH bits, which are standard for hard‑rock and medium‑depth drilling respectively. Both types are typically sized by cutter diameter and length, and buyers should request the specific size range needed.

Are Atlas Copco spare parts genuine or aftermarket?

The catalogue includes Atlas Copco spare parts such as shank adapters, Boomer 281 components and drifter parts. Buyers should ask for authenticity certificates or part numbers to confirm OEM compatibility.

What specifications are common for DTH hammers offered by this supplier?

DTH hammers are usually defined by impact energy (2‑12 kJ), pneumatic or hydraulic drive type, and maximum operating pressure. Request the hammer’s energy rating and pressure limits for project matching.

How are extension rods and MF drill rods typically sized?

These rods are commonly sized by outer diameter (30 mm‑76 mm) and length (typically 2‑6 m per section). Tensile strength and weight per meter are also standard data points buyers request.

What documentation should I request before purchasing?

Ask for mill test reports, material test certificates, and any ISO or CE conformity documents relevant to the product. Third‑party inspection certificates add additional assurance.

Which shipping terms are most used for these drilling tools?

Exporters from China often use FOB Shanghai or CIF destination ports for heavy drilling equipment, allowing buyers to arrange inland transport and customs clearance.

What are the typical packaging methods for the grinding cup?

Grinding cups are usually packed in reinforced cardboard boxes with protective padding, and stacked in wooden crates for container loading to prevent breakage.

Which markets commonly import these Chinese drilling products?

Major importers include mining‑intensive regions such as Africa (South Africa, Zambia), the Middle East (UAE, Saudi Arabia), Southeast Asia (Indonesia, Vietnam) and South America (Chile, Peru).
