Polycrystalline Diamond Compact 350MM Water Well Drill Bits

Core bits are widely used for mineral exploration, geological exploration, water and electricity projects, traffic construction, and building applications for rock core drilling, exploration, and soil investigation.

Available sizes: NQ, HQ, PQ and more.

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

Originally limited to soft shale formations, modern PDC bits can now drill hard interlayer and long hard rock formations thanks to technological advancements and structural improvements.

With continuous quality improvements, PDC bits now perform in harder, more abrasive, and variable formations that were previously unsuitable. This expansion has significantly impacted the balance between diamond fixed cutting teeth bits and cone bits.

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

Suitable for: Quartzite, basalt, solid granite, quartz porphyry, firm conglomerate, strong sandstone, limestone, and more.
