Drag Drill Bit with 3-Blade Wing Step Face Carbide
Professional mining and quarry rock drilling drag bit designed for optimal performance in soft formations.
Product Overview
Manufactured from forged high-quality alloy steel and hard alloy, these drag bits utilize state-of-the-art welding technology and multiple precision heat treatment processes. This ensures the highest penetration rate and longest service life under demanding drilling conditions.
Recommended Applications
Designed primarily for soft formations including sand, clay, and soft rock. Ideal for water well drilling, mining, geothermal drilling, environmental drilling, and exploration applications. Not recommended for coarse gravel or hard rock formations.
Wing Configuration Options
Three-wing bits: Offer faster drilling speeds
Four-wing bits: Provide longer durability and drill straighter holes
Key Advantages
Copper Brazing Technology: Tungsten carbide tips are attached using advanced copper brazing welding, ensuring optimal hardness and preventing alloy flaking
Integrated Body and Wings: One-piece construction prevents wing breakage even when drilling in hard rock formations
Large Flow Course Design: Suitable for both air and fluid drilling without compromising bit strength
Thread Quality
2.3/8" API Reg (good quality) threads precisely machined using CNC equipment to ensure accurate coupling with drill rods.
Construction Options
Available in solid or welded construction. Solid one-piece construction offers maximum durability and is recommended for oilfield and natural gas applications where zero tolerance for error is required.
