About Xi'an Tydrillbits Co., Ltd - Drilling Machines & Tools Supplier in China

Xi'an Tydrillbits Co., Ltd is based in China and currently lists five active products in its catalogue. All items fall under the broader category of Drilling Machines & Tools and are described with specific model designations such as “25mm Pilling Bullet Teeth C31HD” and “Diamond Head 200mm Pdc Concave Drill Bit”. The catalogue includes a mix of PDC (Polycrystalline Diamond Compact) and tricone drill bits, each referenced by size, cutter type or API standard. The supplier’s product list therefore covers both core‑drilling and non‑core drilling solutions used in oil‑field and mining operations.

The five listed products comprise two API‑standardized bits - an API 2 7/8" 3‑Wings Non Core PDC bit and an API Oil Well Tricone Drill Bit - and three additional engineered bits identified by cutter geometry and material grade. Sizes range from 25 mm diameter up to 200 mm length, indicating suitability for a variety of wellbore diameters and formation types. The inclusion of “C31HD” and “PDC” terminology signals the use of high‑density tungsten carbide and diamond‑impregnated inserts, which are common performance criteria in down‑hole tooling.

Product Range and Specialties of Xi'an Tydrillbits Co., Ltd

The catalogue focuses on down‑hole drilling bits, specifically PDC and tricone designs. In the industry, PDC bits are typically graded by cutter hardness (e.g., C31, C33) and by the hydraulic profile such as “concave” or “bullet teeth”, while tricone bits are evaluated by cone material (tungsten carbide) and gauge size. Common specifications buyers look for include cutter diameter (often 10‑25 mm), overall bit length (150‑250 mm), and API classifications like API 7‑1 for oil‑field applications. The supplier’s “AQ BQ NQ HQ PQ” series suggests a progression of impregnated core drill bits, which in practice are differentiated by grade of impregnation and expected wear resistance.

Typical industry grades for the listed sizes include IC (International Classification) levels for PDC wear resistance and API RP 5C test results for tricone durability. Buyers often request material test reports confirming tungsten carbide composition (often >90 % WC) and diamond particle size (typically 0.5‑2 mm) for PDC bits. The presence of both core and non‑core options allows operators to select tools matched to formation hardness and expected penetration rates.

Trade and Export Information - Xi'an Tydrillbits Co., Ltd

China is a major exporter of down‑hole drilling equipment, with most shipments routed to oil‑producing regions in the Middle East, West Africa, Southeast Asia and Latin America. Drilling bits fall under HS Chapter 84 (Machinery) and are usually declared with HS codes 8465‑90 for other drilling or boring tools. Export logistics commonly employ 20‑ft or 40‑ft containers packed in wooden crates, with Incoterms such as FOB Shanghai or CIF Dubai used for bulk orders. Buyers typically require proof of conformity to ISO 9001 quality management and API 7‑1 or API 5C standards, although the specific certifications held by this supplier are not listed in the provided facts.

Regulatory inspection in importing countries often includes verification of material safety data sheets (MSDS) and compliance with local drilling equipment regulations. Chinese manufacturers of drilling bits frequently obtain third‑party testing reports to satisfy overseas buyers, and many exporters participate in traceability programs that track bit grade and manufacturing batch.

Sourcing from Xi'an Tydrillbits Co., Ltd - Buyer Guidance

When sourcing from Xi'an Tydrillbits, buyers should request the latest product data sheet, including cutter grade, hydraulic profile and API designation for each bit. It is advisable to ask for a recent ISO 9001 audit report or equivalent quality system documentation, as well as material test certificates confirming tungsten carbide and diamond content. Sample procurement is common for PDC bits; a typical minimum order quantity ranges from one to five pieces per size, with lead times of 4‑6 weeks after order confirmation.

Before confirming a purchase, verify packaging details (e.g., double‑wall wooden crates, moisture‑proof liners) and ensure the shipping terms align with the buyer’s preferred Incoterm. Request a third‑party inspection report for the specific batch, especially for API‑specified bits, to confirm compliance with the required wear‑resistance and tensile strength standards.

What sizes of drill bits does Xi'an Tydrillbits offer?

The supplier lists bits ranging from a 25 mm bullet‑tooth bit to a 200 mm PDC drill bit, covering typical diameters used in oil‑well and mining drilling.

Are the listed bits compliant with API standards?

Two products are explicitly labeled with API designations - an API 2 7/8" 3‑Wings Non Core PDC bit and an API Oil Well Tricone Drill Bit - indicating they meet the relevant API specifications.

What material grades are used in the PDC bits?

The catalogue mentions a C31HD grade, which in the industry corresponds to a high‑density tungsten carbide matrix with diamond particles, offering a balance of hardness and impact resistance.

Which certifications should a buyer request from this supplier?

Buyers should request ISO 9001 quality‑system certification and any API test reports (e.g., API 7‑1 or API 5C) that verify the performance of the listed bits.

What is the typical packaging for these drill bits?

Drilling bits are usually packed in moisture‑resistant wooden crates or reinforced cartons, often with individual protective sleeves to prevent damage during transport.

What are common Incoterms used for exporting Chinese drill bits?

Exporters from China often use FOB Shanghai or CIF Dubai for drilling equipment, allowing the buyer to manage freight or receive delivered cost respectively.

How can I obtain a sample before placing a larger order?

Buyers can request a single piece sample of the desired bit size; suppliers generally ship samples in a small crate and provide a test report with the shipment.

What documentation is needed for customs clearance?

Customs typically requires a commercial invoice, packing list, certificate of origin, and any applicable test or quality certificates referenced on the invoice.
