Import Best Quality 8 1/2 " Matrix Body Pdc Bit — Buy in wholesale FOB from Supplier in China

The 8 1/2 inch matrix body PDC bit from Cangzhou Great Drill Bit Co., Ltd. is built for full-size hole opening in medium to hard formations common to oil and gas exploration. The matrix body construction bonds tungsten carbide particles in a copper-nickel alloy matrix, giving higher abrasion resistance than steel-body alternatives. Strategic placement of polycrystalline diamond compact cutters on the face produces a shearing action that removes rock efficiently without the impact damage associated with roller cone bits. The 8 1/2 inch diameter matches standard API bit sizes for compatibility with common bottom-hole assemblies.

Matrix body PDC bits typically use a synthetic diamond table bonded to a tungsten carbide substrate for each cutter, with cutter exposure, back-rake angle, and layout optimised for the target formation. Thermal stability is managed through cutter grade selection and internal coolant channels that direct drilling fluid across the cutting face to prevent thermal degradation of the diamond table. The standard API connection pin must match the drill collar thread specification; confirm whether the supplier provides a regular pin, slimline, or double-shoulder connection. Gauge protection is normally provided by natural or synthetic diamond grit inserts to prevent diameter loss in abrasive intervals.

This bit suits directional drilling, horizontal wellbores, and mining exploration where rate of penetration and long bit life reduce tripping frequency. Operators in shale plays, sandstone reservoirs, and carbonate formations with compressive strengths below 25,000 psi typically report favourable performance. Buyers should confirm cutter quantity, cutter size (commonly 13 mm or 16 mm), and whether the bit is designed for push-the-bit or point-the-bit steerable motor applications. Cangzhou Great Drill Bit Co., Ltd. is located in Hebei Province, a region with established machining and heat-treatment infrastructure for oilfield tooling.

Cangzhou Great Drill Bit Co., Ltd. operates from Junziguan Industry Zone in Hejian, Hebei Province, China. The company holds a harbor trust tier on the sourcing platform, indicating baseline verification status. The response rate is recorded at 0.00 percent with an average response time of zero hours, which suggests the supplier has not yet established a track record of inquiry response through this channel. Buyers should therefore expect to initiate contact directly and may need to allow additional time for quotation and technical clarification.

The supplier's profile does not state founding year, employee count, revenue, clientele, or specific manufacturing certifications. The location in Hejian places it within a concentration of Chinese drill bit and oilfield tooling manufacturers, which provides access to mature supply chains for tungsten carbide, steel forgings, and CNC machining. Buyers should request factory audit reports, quality management system documentation, and reference installations before committing to large orders. Direct technical discussion about cutter sourcing, matrix infiltration processes, and API specification compliance is advisable.
