These PDC concave drill bits are primarily intended for drilling in soft to medium formations like mudstone, limestone, shale, sandstone, and granite.Well-suited for various tasks such as hydrogeological exploration boreholes, gas drainage holes, agent plug-holes, and grouting boreholes, especially in medium-hard to hard rock formations.Operate efficiently under low drilling pressure and medium-low drive speed, facilitating efficient drainage.

Features:

Equipped with wing drill bit gauges made of cemented carbide, ensuring high hardness, excellent wear resistance, and good toughness even under high temperatures. This design choice helps reduce overall drilling costs.

Comprising three or five water holes, effectively cooling the PDC cutter and flushing out mudstone debris, thus minimizing downtime and enhancing on-field efficiency.

Incorporating two 1308 PDC cutters for the pillar and two middle water holes, efficiently cooling the PDC cutters while simultaneously clearing mudstone debris, preventing damage to the compact (PDC cutter ) components..The concave-type PDC (Polycrystalline Diamond Compact) non-core drill bit is expertly engineered for outstanding performance in hard rock formations. Tailored to excel in demanding environments, it stands out for:

1. Hard rock formations: Specifically crafted for drilling in challenging rock formations.

2. High-speed cutting and precision: Designed to meet the demands of drilling operations requiring swift cutting and precise results.

Featuring a concave design and diamond-coated cutting edges, this drill bit efficiently drills through even the toughest rock formations. Its non-core design allows for easy removal from the wellbore, reducing downtime and boosting overall drilling efficiency. Ideal for applications in oil and gas, mining, and construction industries, it's a dependable and cost-effective solution for hard rock drilling.
