Integrated Alloy Drag Bit (Specialized for F≤4 Soft Rock Efficient Drilling)
High-Quality Alloy Blades
Fast Soft Rock Drilling
F≤4 Specialized
The Integrated Alloy Drag Bit features die-cast integrated alloy steel construction combined with high-quality alloy blades, specifically designed for F≤4 soft rock and slightly soft formations. With durable, wear-resistant steel body that resists deformation, and sharp alloy blades, this bit delivers fast drilling speed and smooth cuttings removal in soft formations. Suitable for water wells, geological surveys, soft formation opening, and other scenarios, offering a cost-effective solution for efficient soft rock drilling.
Widely used in water well drilling opening and completion, geological survey soft formation sampling, soft formation grouting hole drilling, open-pit soft rock blast hole drilling, soft formation foundation engineering drilling, and other scenarios. Particularly suitable for large-scale rapid soft rock drilling projects.
Core Advantages
Integrated Alloy Steel · Durable & Wear-Resistant
The steel body utilizes die-cast integrated alloy steel construction without splicing seams, with structural strength far exceeding ordinary split-type bits. Excellent wear resistance, impact resistance, and deformation resistance ensure minimal breakage and wear during soft formation drilling, significantly extending service life and reducing bit change frequency and construction costs.
High-Quality Alloy Blades · Efficient Soft Rock Cutting
Equipped with high-quality alloy blades featuring sharp cutting edges and hardness optimized for soft rock characteristics. For F≤4 soft rock (soil layers, mudstone, soft shale, etc.), cutting resistance is minimal with fast rock breaking speed. Compared to PDC bits, drilling efficiency in soft formations is significantly higher, enabling rapid completion of soft rock drilling operations.
Drag Blade Structure · Smooth Cuttings Removal
Classic drag blade wing design combined with blade opening structure allows cuttings to be rapidly removed with circulating medium during drilling, preventing cuttings accumulation and sticking. Ensures continuous efficient drilling, particularly suitable for large cuttings removal requirements in soft formations, improving drilling continuity.
Soft Rock Specialized Adaptation · Lower Drilling Cost
Specifically optimized for F≤4 soft rock, eliminating need for high-cost PDC cutters. Alloy blades offer better cost-effectiveness with fast drilling speed in soft formations and low bit change frequency. Significantly reduces per-meter drilling cost, suitable for large-scale soft rock drilling projects while balancing efficiency and cost.
Complete Size Coverage · Wide Adaptability
Covers various mainstream borehole sizes from small to large diameters, compatible with different drill rig models. Thread types are customizable to meet borehole size requirements for water wells, geological surveys, soft formation opening, and other scenarios. Easy operation and strong versatility.
Applications
Suitable Formations
F≤4 soft rock and slightly soft formations including soil layers, mudstone, soft shale, soft red sandstone, loose sand layers, etc.
✅ Specifically designed for F≤4 soft rock, maximizing soft rock drilling efficiency
Not recommended for medium-hard and harder formations (F＞4, such as limestone, granite).
Drilling Method
Rotary Drilling – Recommended to use clean water or low-solid mud circulation, utilizing drag blade structure and opening design for rapid cuttings removal. Control drilling pressure and rotation speed to avoid excessive loads causing blade wear, improving drilling efficiency and bit life.
