Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Power Drilling: Designed for drilling into concrete, masonry, and ALC blocks using SDS-type impact drivers. The carbide-tipped edge ensures precision and efficiency in hard materials.
  • Impact Resistance: The SDS shank type guarantees stable attachment to hammer drills, enabling high-impact drilling for professional and heavy-duty applications.

Key features

  • 1. Advanced Carbide-Tipped Material Technology

    • With a carbide-tipped design, you can drill through concrete and masonry with 20% longer bit life compared to standard steel-tipped bits*. The hardened carbide ensures resistance to wear and extreme temperatures, maintaining sharpness even in heavy-duty applications.

  • 2. SDS Shank for Enhanced Stability

    • With an SDS-plus shank, you can achieve 30% better grip and stability in impact drivers* than hex-shank bits, reducing slippage during high-impact drilling. This design absorbs vibrations, prolonging tool and bit lifespan.

  • 3. High-Speed Performance for Commercial Use

    • With optimized cutting geometry, you can drill 25% faster than non-impact bits* in concrete and brick, thanks to the carbide’s precision and the SDS shank’s compatibility with high-torque impact drivers.

  • 4. Commercial-Grade Durability

    • Designed for continuous commercial use, this bit can handle 10+ hours of daily drilling* without losing sharpness, making it ideal for construction sites or frequent masonry projects.

  • 5. Japanese Quality Assurance

    • Certified under Unika’s rigorous Japanese quality control standards, you can trust precision-engineered durability and compliance with industrial-grade specifications.
