Retrac Drill Bit

Pulanka's Retrac drill bits feature carbide crafted from low-cobalt, medium-grain material, delivering performance on par with top international brands. These premium buttons provide exceptional rock drilling capabilities, withstanding fracture risks during high-stress operations.

The optimized front angle design and precision grinding of the cutting edge achieve an effective combination of efficient drilling advancement and smooth bit withdrawal, significantly reducing the risk of bit jamming. The scientifically designed spiral flutes with optimal helix angles ensure rapid and thorough chip evacuation, preventing accumulation and blockage.

This guarantees stable drilling operations and enhances overall construction efficiency. The comprehensive product specification series caters to diverse construction scenarios including mining, water conservancy, hydropower, and highway projects. A rigorous quality control system ensures stable and reliable performance in professional applications.

Feature:

Our Medium & Deep Hole Drilling Series LF89-T51

1. Precise Drilling: Retractable design minimizes deviation, ensuring straight holes and boosting mining profitability.

2. Excellent Comprehensive Performance: Improves borehole straightness during drilling with superior slag discharge (flushing) capability. Effectively handles soft-to-hard abrasive rock formations, reduces bit face wear and deformation, and ensures drilling quality and efficiency.

3. Durable & Cost-Effective: Constructed with high-quality cemented carbide (e.g., tungsten carbide) and a rational structural design, featuring strong wear and breakage resistance. Low carbide shedding rate and long service life minimize replacement frequency and reduce operating costs.

4. Easy Replacement Design: Easy to remove the drill bit, not easy to get stuck.Simple replacement shortens equipment downtime and lowers consumable costs.

Application Scenarios：

Underground Mining Operations: Suitable for bench drilling and long-hole drilling in underground mines (e.g., metal mines, coal mines). Pre-drills holes for blasting operations and enables stable drilling in complex rock formation conditions.

Tunnel & Drift Excavation: Used for pre-drilling in tunnel and underground drift excavation projects. Cooperates with excavation equipment to provide precise holes for subsequent blasting or support construction, adapting to soft-to-hard abrasive rock formations.

Quarry & Construction Projects: Rock drilling for blasting in quarries; rock drilling operations in building foundation construction (e.g., pile foundations, foundation treatment) and infrastructure projects such as roads and dams.
