12-Inch Tricone Drill Bit – Milled Tooth & Tungsten Carbide Insert Options

The 12-inch Tricone Drill Bit is a versatile and robust rotary tool used in various drilling applications including oil and gas exploration, geothermal wells, water well drilling, and foundation construction. Featuring a tricone design with three conical cutters and configurable cutting structures, this bit is suitable for a wide range of formations — from soft to ultra-hard. Options include Milled Steel Teeth (MT) for soft formations and Tungsten Carbide Inserts (TCI) for more abrasive and harder formations. With bearing options including open roller, sealed roller, and sealed journal bearings, this bit is engineered to withstand various loads and depths. It features precision-fit cutting elements, durable gauge protection, and customizable nozzles for efficient mud circulation and cooling.
