• 3-Wing or 4-Wing Configuration for Balanced Rock Cutting – Choose between 3‑wing for faster penetration in soft to medium‑hard formations or 4‑wing for increased stability in harder, more fractured rock layers. Both designs use premium polycrystalline diamond compact (PDC) cutters to shear rock efficiently while reducing vibration and improving hole straightness.
• Non-Coring Solid‑Face Design for Continuous Full‑Hole Drilling – Unlike core bits, this non‑coring (coreless) PDC bit completely destroys and removes the rock formation without retrieving a sample, enabling fast, uninterrupted drilling in geological exploration, water wells, and mining projects where core extraction is not required.
• Compatible with 76mm and 89mm API Drill Rods – Engineered with standard API Reg threads to fit common 76mm and 89mm drill rods, ensuring a secure, leak‑free connection for exploration rigs, water well drillers, and geotechnical equipment.
• Construction for Hard Rock & Abrasive Formations – Made from a high‑strength steel body with wear‑resistant PDC cutters and gauge protection to withstand challenging conditions, including granite, limestone, sandstone, and other medium‑hard to hard rock layers, delivering long service life and reduced downtime.
• Optimized Hydraulic Design for Efficient Chip Removal – Features strategically placed water jets to cool the cutters and flush rock cuttings away from the face, preventing bit balling and maintaining consistent penetration rates in deep‑hole and continuous drilling applications.
