High-wear PDC cutters on a one-piece steel body delivering a high rate of penetration and long footage — suited to medium-hard to hard formations in water well drilling, geological prospecting and coal-bed methane drainage.
A four-blade layout with generous junk slots keeps balling risk low and full-hole water well drilling efficient.
PDC core bits carry diamond compacts on annular blades, shearing a ring of rock while preserving an intact core — combining high penetration with high recovery. Used in water well, geological and engineering coring. The 152 mm size is offered with different blade counts and core diameters.
Key features: · Annular shear blades, fast penetration · Intact core, high recovery · Wear-resistant PDC, long runs · Blade count and core size customizable
All products use premium diamond grit and imported matrix powders, processed by hot-press sintering, laser welding and piece-by-piece inspection. Hardness, density and bond strength are sampled before shipment to guarantee batch-to-batch consistency.
OEM/ODM supported: dimensions, matrix hardness, diamond concentration, threads and connections can be customized to your drawings or rock conditions. Neutral packing and private label available; samples in 7–15 days.
Factory-direct pricing with no middlemen. Our technical team advises on model selection and drilling parameters. Fast delivery with ample stock of standard sizes.

Description from the Supplier
The following content is provided by the manufacturer, covering product features, factory advantages and how to work with us.
Product Description
PDC Drill Bits · 152mm Four Blades PDC Diamond Non-Core Drill Bits for Water Well Drilling
PDC bits braze polycrystalline diamond compact cutters onto a high-strength alloy-steel body. Their working life is 10–30 times that of tungsten-carbide bits and drilling efficiency can be raised by about 60%, with no re-sharpening needed — reducing labour intensity and overall cost.
The range covers two- and three-wing anchor bits, PDC core bits, non-coring (full-face) bits and multi-wing bits for coal-seam roof bolting, water wells, and highway, bridge and railway foundations and geological exploration. Optimized hydraulic layouts give smooth cuttings removal and effective cooling.
Product Advantages
More than 20 years of professional experience in diamond tools; the factory has been producing synthetic diamond tools since 2009.
Factory-direct supply: we are the manufacturer, with no middleman — better prices at the same quality.
High-grade raw materials: imported cobalt and nickel powders and high-quality diamond single crystals, with a formula validated by testing.
Advanced processes and strict inspection: hot-press sintering, vacuum brazing and laser welding, with piece-by-piece inspection and sampling of hardness, density and bond strength.
Efficiency and life: PDC anchor bits last 10–30 times longer than tungsten-carbide bits and raise efficiency by about 60%; impregnated bits drill fast with a long service life.
Full range and customization: AQ–PQ and T2/T6 series, common sizes 24–600 mm; matrix hardness, diamond concentration, threads, packing and buyer labels can all be customized (OEM/ODM).
Fast response and reliable lead time: enquiries answered within 10 hours, about 7 days delivery when the mould is ready and about 12 days when a new mould is required.
Packing & Delivery
Standard packing is an inner box in a thick export carton; neutral packing or your own packing method is available on request. Port of shipment: Guangzhou / Shenzhen. Trade terms: FOB, CFR, CIF, EXW. Payment: T/T, L/C, D/P, Western Union and PayPal.
