QL50 QL60 QL80 Down the Hole Dth Hammer Button Drill Head

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Performance Drilling: Designed for drilling into hard materials like rock and concrete using down-the-hole (DTH) technology. The tungsten carbide tips ensure efficient penetration and extended tool life.
  • DTH Mechanism: Utilizes a percussive rotation system for high-impact drilling, reducing wear and enabling faster hole formation in tough substrates.

Key features

  • 1. Material Technology: Tungsten Carbide Cutting Edges

    • With tungsten carbide cutting edges, ensure prolonged durability in hard rock and concrete drilling. These edges outlast standard steel tips by up to 30% in abrasive conditions*, providing consistent performance in demanding environments.

  • 2. Interactive Design: Hexagonal Tapered Shank

    • With a hexagonal tapered shank, achieve secure attachment to drills/hammer drills and precise alignment compared to smooth-shank designs*. This reduces slippage and enhances operational stability during high-impact drilling.

  • 3. Performance Parameters: Forged High-Strength Steel Construction

    • Forged high-strength steel construction delivers 20% faster penetration in dense materials like granite and reinforced concrete than non-forged alternatives*. The hardened body withstands extreme pressures, ensuring reliable operation.

  • 4. Scenario Solutions: Versatile Industrial Applications

    • Engineered for continuous operation in mining, construction, and geotechnical projects, this drill head adapts to heavy-duty scenarios requiring rapid, deep-hole drilling in hard substrates*.

  • 5. Certification Standards: Durable Material Compliance

    • Constructed with carbide and forged steel meeting industrial-grade durability standards, this drill head is backed by a 3-month warranty for commercial and industrial use*.

Supplier's note

  1. Technical Breakthroughs:

    • Tungsten Carbide Tips: Triple the wear resistance of traditional steel tips, enabling longer drilling cycles in abrasive environments.
    • Forged Steel Body: 20% stronger than cast alternatives, ensuring structural integrity under high冲击 loads.
    • Hexagonal Shank Design: Reduces slippage by 40% compared to round shanks, enhancing tool stability.

  2. Optimal Version Selection:

    • QL50 (Base): Ideal for light to medium-duty drilling in standard rock conditions. Perfect for small-scale construction or maintenance tasks.
    • QL60 (Advanced): Offers 15% higher impact energy than the base model, making it suitable for medium-heavy mining operations requiring extended durability.
    • QL80 (Pro): The Pro version’s 30% boosted impact energy and extreme temperature tolerance enable heavy-duty mining in harsh environments. Its tungsten carbide tips paired with forged steel ensure safe handling of abrasive materials like basalt or granite.
