Product Description

Application :Large-diameter assembled drill bits find extensive application in various construction projects, including bridges, highways, and railways. This versatile series of drill bits is tailored for a wide range of geological formations, such as shale, limestone, cobblestone, dolomite, and conglomerate.

Features:

1. Formation Compatibility: Ideal for medium to medium-hard formations with notable fracture resistance, including hard shale and sandstone.

2. Bearing Design: Equipped with a non-sealed roller bearing for smooth and efficient operation.

3. Enhanced Durability: The palm's tip is welded with a hard surface, and the carbide blade is securely protected by a gauge pressed into the head's outer diameter, ensuring longevity and performance.

4. Reinforced Cone Gauge: The cone gauge surface is fortified with cemented carbide press blocks, providing additional strength and stability.

Product Structure Enhancements:

1. Cutting Structure Optimization:

   • Blade Placement: By strategically positioning tapered blades in the permanent contact area and wedge-shaped blades in the alternating contact area, drilling efficiency is significantly boosted.
   • Diamond Blade Reinforcement: A diamond blade is placed in the high-wear permanent contact area, enhancing the cutting structure's wear resistance.
   • Tungsten Carbide Protection: The tungsten carbide blade on the cone's top surface shields it from abrasion, ensuring prolonged use.

2. Instrument Structure:

   • Active Cutting Volume Protection: The drill bit incorporates an active cutting volume protection insert, offering excellent gauge protection and drilling capabilities.

3. Bearing Structure Upgrades:

   • High-Precision Bearings: Utilizes high-precision journal bearings with a ball-locking mechanism for the cone.
   • Hardface Coating: The bearing surface is coated with hardface material, and the tapered bearing is inlaid with anti-friction alloy, improving wear resistance and seizure resistance.
   • Larger Outrigger Bearing: Compared to tri-cone bits, the larger outrigger bearing allows for higher weight on bit (WOB) and greater reliability.

4. Hydraulic Design Improvements:

   • Small-Angle Waterway: The small-angle waterway design increases the thickness of the palm's tip, effectively preventing waterway erosion.
   • Optimized Hydraulic Structure: Enhancements in the hydraulic structure improve cleaning efficiency and increase the penetration speed, ensuring smoother and faster drilling operations
