15 1/2 Inch Iadc 537 Rubber Sealed Bearing Tci Tricone Rock Bit For Medium Hard Formation

Introduction

1. High-strength and high-toughness carbide teeth are used to improve the impact resistance of the teeth and reduce the tooth
breakage rate;
2. The optimally designed tooth row number, tooth number, exposed tooth height and unique alloy tooth shape give full play to the
cutting ability and cutting speed of the drill bit;
3. Widely used in petroleum exploration, mining exploration, geothermal wells, hydrological exploration and other fields.
Our company can provide specific solutions according to the actual drilling situation, and customize assembled drill bits of any
diameter, including large-diameter machine pile drill bits, different types of drill bits, reaming bits, directional drilling
bits, etc.
