145mm 4‑Blade Arc‑Shaped PDC Bit

Our 145 mm 4‑blade arc‑shaped PDC bit is purpose‑built for tackling tough, highly abrasive rock conditions, widely deployed in water well drilling, geothermal drilling and geological exploration projects.

Equipped with premium 1613 ultra‑hard PDC cutters , this drill bit delivers exceptional impact resistance and wear resistance. The arc‑shaped blade structure optimizes rock‑breaking contact area, enhances rock shearing efficiency, and effectively mitigates cutter chipping when drilling into hard granite, hard sandstone and other dense abrasive formations.

Adopted robust 3 1/2 REG thread connection , it ensures stable, reliable connection with drill strings, convenient for on‑site assembly and disassembly. The bit body adopts high‑strength alloy substrate, greatly improves overall structural stability, reduces vibration during drilling, extends service life of cutters and the whole bit.

This 4‑blade arc‑shaped PDC bit performs outstandingly in hard granite formations. It balances penetration rate and service life, lowering your consumable replacement frequency and overall drilling cost. It is a reliable drilling solution for drillers and drilling contractors focusing on hard‑rock drilling works.

Application Range：Hard granite, compact hard sandstone, tough metamorphic rock, water well, geothermal hole, geological prospecting drilling
