75mm 3‑Blade Arc‑Angle Non‑Core PDC Drill Bit

Factory‑direct 75mm 3‑blade arc‑angle non‑core PDC drill bit , engineered for highly abrasive and disturbed complex subsurface conditions. Equipped with 1308 enhanced domed‑bread‑style PDC cutters , its arc‑angle blade geometry optimizes junk‑slot flow path, lowers drilling torque and absorbs heavy impact from cobbles and gravels, mitigating chipping and premature cutter failure.

This bit delivers consistent penetration rate for sandstone, sandy conglomerate, cobble interbeds, fractured weathered rock and mixed complex formations. It features outstanding impact resistance and long‑term wear performance. Widely deployed for non‑coring drilling jobs: geological exploration, building site investigation, geotechnical survey, mining tunneling and water well drilling. Compatible with standard geological drill rigs; custom thread connections available. Bulk supply for overseas contractors, drilling service companies and international distributors.

Key Advantages

1. 1308 enhanced domed PDC cutters: improved impact resistance against gravel & cobble shock, extended service life
2. Optimized 3‑blade arc‑angle profile: superior cuttings evacuation, avoid bit balling, smoother rotary drilling
3. Heavy‑duty forged steel body, high wear tolerance for fractured and variable strata, minimize frequent bit replacement
4. Multi‑purpose suitability: geological survey, geotechnical investigation, construction site exploration, mining, water well & shallow geotechnical drilling
5. Original manufacturer, custom thread options, bulk order support for global engineering projects

Suitable Formations

Sandstone, sandy conglomerate, cobble layers, fractured weathered strata, mixed complex interbedded formations, gravel interlayers

Applications

Geological exploration, geotechnical investigation, building site survey, mining drilling, water well drilling, shallow geotechnical engineering.
