For mining and quarrying operations that prioritize operational efficiency and cost control, the Henglong long-life 7-tooth 7-degree mining drill bit delivers exceptional performance in rock drilling applications. This drill bit is meticulously engineered to extend service life while maintaining optimal drilling performance, specifically designed for medium-hard to hard rock formations. Ideal for blast hole drilling, production drilling, and exploration projects.
Key Advantages
7-Tooth Configuration for Balanced Drilling Efficiency
7-Degree Cutting Angle for Optimal Stability and Cost Savings
Long-Lasting Structure for Maximum Cost-Effectiveness
The drill bit body is forged from high-strength alloy steel and treated with a proprietary heat treatment and hardening process, enhancing core toughness and corrosion resistance. Tooth surfaces are reinforced with wear-resistant hard alloy coating, and the drill shank connection is precisely machined to prevent slippage while ensuring stable, reliable power transmission.
Industrial Applications
Open-Pit Mining Blast Holes
Drilling uniform diameter blast holes in coal and iron mines for explosive placement
Underground Production Drilling
Ore extraction in underground mine tunnels; extended lifespan reduces frequent bit changes in hard-to-reach areas
Exploration Drilling
Conducting geotechnical surveys and ore body mapping with consistent drilling accuracy
Quarry Operations
Drilling foundation holes and fragmentation holes for construction aggregate production, balancing speed and durability
In today's competitive mining market, every cost saving per meter drilled accumulates into significant project savings. The Henglong long-life seven-tooth, seven-degree mining drill bit incorporates three key cost-saving elements: the seven-tooth design reduces drilling time, the seven-degree angle minimizes maintenance downtime, and the long-life construction significantly lowers replacement costs. For mining companies seeking to enhance productivity without increasing equipment budgets, this drill bit represents a strategic investment in long-term cost-effectiveness and operational reliability.
