4‑Blade Arc‑Angle Non‑Core PDC Bit

Manufactured by professional drilling tool factory, this four‑blade arc‑angle non‑core PDC bit features optimized arc‑profile crown geometry for balanced force distribution, low drilling vibration and well‑formed borehole wall. Equipped with 1308 chamfer C11 round PDC cutters , upgraded brazing technology delivers balanced impact resistance and abrasion resistance. It realizes efficient shear‑rock breaking in intact rock formations and greatly improves rate of penetration (ROP), cutting overall operational cost for field projects.

It performs well in intact rock formations: tuff, gneiss, bluestone, limestone, marble, sandstone, basalt. Multiple standard thread connections are available: Z‑42, Z‑50, Z‑76, Z‑88, 2 3/8REG, 2 7/8REG, 3 1/2REG, 4 1/2REG, NC26, NC31, compatible with most common drilling rigs. Widely applied in geological exploration, mining exploitation, water well drilling, coal mine drilling, slope stabilization anchoring, bridge construction and other engineering projects. We supply to Southeast Asia, Africa, Central Asia, Russia and other global markets, supporting OEM customization and bulk order.
