Spiral PDC Core Bit

Factory‑direct supplied spiral PDC core bit features optimized spiral water‑groove design for smooth cuttings discharge and anti‑clogging performance. Reinforced cutting structure is specially engineered for high‑hardness rock formations, delivering remarkable penetration rate and higher core recovery ratio.

Available outer diameters: 76mm, 91mm, 93mm, 110mm, 112mm, 130mm, 132mm, 146mm, 151mm. Custom thread connections are available to match most standard core barrels and drilling rigs.

It works reliably in limestone, bedrock, sandstone, granite, basalt, bluestone and other medium‑hard to hard rock formations. Widely deployed for geological prospecting, rock core sampling, mine exploration, water well drilling and geotechnical investigation projects. Robust bit body together with impact‑resistant PDC cutters reduces frequent bit replacement and downtime, lowering overall site drilling cost. Bulk order and drawing‑based custom manufacturing are accepted.

Spiral‑flute PDC core bit delivers outstanding performance in hard‑rock drilling with efficient cuttings removal and high‑integrity core samples. Multiple sizes in stock, custom threads optional. Suited for granite, basalt, limestone and other tough formations for geological survey, mining coring, water‑well construction. Direct from manufacturer, bulk purchasing for overseas projects supported.

This spiral PDC core bit adopts spiral‑flute hydraulic layout to optimize drilling fluid circulation and mitigate cuttings accumulation & bit jamming risk in hard and fractured interbedded strata. Heat‑treated bit body assembled with high‑performance PDC cutters maintains stable ROP in abrasive rock including limestone, bedrock, granite and basalt.

Full‑range standard sizes from 76mm to 151mm are ready for shipment. Thread profiles can be customized to fit single‑tube / double‑tube core barrels and local drilling rig connections. It fits field geological sampling, mineral resource exploration, water‑well completion, pre‑piling geotechnical survey and slope stability investigation. As original manufacturer, we offer formation‑oriented bit selection support and reliable delivery for overseas wholesalers and engineering contractors.
