Power Tool Sintered Fast Cutting Hole Saw Diamond Core Drill Bit for Granite Marble Concrete Ceramic

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Efficiency Drilling: Diamond-tipped edges enable rapid cutting through hard materials like granite, marble, concrete, and ceramic tiles, ensuring minimal effort and maximal productivity.
  • Precision and Longevity: Sintered diamond-steel construction maintains sharpness and accuracy over extended use, reducing downtime for replacements.

Key features

  • 1. Material Technology

    • With diamond-embedded sintered steel construction, you can achieve precise, long-lasting cuts in hard materials like concrete, granite, and ceramic tiles. The diamond-tipped design ensures 30% faster cutting compared to traditional carbide-tipped bits*.

  • 2. Interactive Design

    • With an ergonomic cylindrical shape and pointed diamond-tipped edges, you can ensure stable control and accurate hole placement, reducing misalignment during drilling. The round shank design offers better compatibility with power tools than hexagonal shank alternatives*.

  • 3. Performance Parameters

    • With a range of diameters (6mm to 60mm) and customizable working lengths (12mm to 100mm), you can adapt to diverse drilling needs, from small-scale repairs to large commercial projects. The 20+ size options outperform single-diameter competitors*.

  • 4. Scenario Solutions

    • Designed for professional use in construction and renovation, you can handle continuous drilling in hard materials like marble and concrete. The durable steel body withstands heavy-duty use, ideal for commercial settings compared to consumer-grade bits*.

  • 5. Certification Standards

    • Backed by CE certification, you can trust compliance with safety and quality standards for industrial use. This certification ensures reliability beyond uncertified alternatives*.

Supplier's note

  1. Three Technical Breakthroughs:

    • Diamond Sintering: The Pro Model’s diamond grit is bonded under high pressure, tripling abrasion resistance compared to standard carbide bits.
    • Extended Working Lengths: The Pro’s 100mm depth enables drilling in 20cm-thick concrete, ideal for structural renovations.
    • Universal Shank Compatibility: Round shanks fit 90% of power tools, eliminating adapter needs.

  2. Optimal Version Selection:

    • Base Model: Best for DIYers or small projects requiring 6–30mm holes (e.g., tile repairs).
    • Advanced Model: Suited for contractors needing mid-range durability and 6–50mm flexibility (e.g., HVAC installations).
    • Pro Model: Recommended for industrial users handling thick materials or high-volume drilling (e.g., commercial construction).

*Pro Model lifespan exceeds industry benchmarks by 40% due to advanced diamond grain distribution.
