Polycrystalline Diamond Compact (PDC) 350mm water well drill bits are engineered for superior performance in demanding drilling applications. These professional-grade bits combine advanced diamond technology with robust construction for reliable operation.

Professional water well diamond PDC core drilling bits are extensively used across multiple industries:

• Mineral exploration and geological surveys
• Water and electricity infrastructure projects
• Transportation and construction development
• Building foundation soil investigation

NQ, HQ, PQ and additional custom sizes available

• Tricone bits (roller rock bits) in all standard sizes
• PDC cutter/insert types: 1304, 1305, 1306, 1308, 1310, 1313, 1613, 1616, 1916 (oil or mining type)
• PDC non-core bits and coring bits (46mm to 216mm diameter)
• PDC anchor bits for roof bolting (25mm to 43mm diameter)
• Tungsten carbide drill bits: twin-wing coal bits, chisel bits, cross bits, button bits, hammer bits
• Drill rods: hex, twist, spiral configurations

Originally developed for soft shale formations, modern PDC bits now deliver exceptional performance in hard interlayer and long hard rock formations through continuous technological advancements and structural improvements.

With ongoing quality enhancements, PDC bits now effectively drill harder, more abrasive, and variable formations previously unsuitable for diamond fixed cutting teeth bits. This technological evolution has significantly shifted the balance between diamond bits and traditional cone bits.

Ideal for soft to medium hard rock strata, advanced PDC bits can now handle rocks with grade 10 hardness. Widely implemented in domestic coal mining operations.

Quartzite, basalt, solid granite, quartz porphyry, firm conglomerate, strong sandstone, limestone, and similar geological formations.
