Supplier's note

  1. Three Breakthroughs:

    • Cobalt-plated finish: 20% higher heat resistance than uncoated chucks, enabling prolonged drilling in high-temperature environments.
    • Tungsten carbide reinforcement: The Pro model’s 30% tungsten content triples wear resistance compared to standard steel chucks.
    • Keyless design: Reduces bit change time by 50% versus traditional keyed chucks, enhancing productivity in fast-paced workflows.
  2. Version Selection Guidance:

    • Base Model: Ideal for occasional DIY users (e.g., homeowners drilling through drywall or soft stone).
    • Advanced Model: Suited for contractors needing mid-range durability (e.g., drilling through brick or tile).
    • Pro Model: Engineers and industrial workers benefit from its extreme heat resistance and large bit capacity for tasks like drilling reinforced concrete or steel rebar.

*Pro Model tungsten carbide content exceeds industry benchmarks by 10%, ensuring unmatched longevity in abrasive materials.
