Triangular Shank Dry Porcelain Diamond Core Drill Bit Tile 5-100mm Vacuum Brazing Technology Concrete Masonry Drill Bit M14 35mm

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Hard Material Drilling: Equipped with diamond-coated grit and vacuum brazing technology, the drill bit efficiently cuts through ceramic, porcelain, glass, concrete, and masonry with minimal heat damage.
  • Precision Control: Features size and depth markings (e.g., 5–100mm diameters, adjustable depth up to 35mm) for accurate hole creation and material thickness adaptation.

Key features

  • 1. Diamond Grit Coating for Hard Material Precision

    • With diamond grit coating, you can effortlessly drill through ceramic, porcelain, and glass without heat damage, ensuring clean cuts in materials that traditional drills struggle with. ~30% faster penetration* compared to standard carbide-tipped bits.

  • 2. Precise Diameter & Depth Markings for Customized Drilling

    • With clear diameter markings (5–100mm) and adjustable depth indicators, you can select the exact hole size and depth needed for projects like tile installation or masonry work, eliminating guesswork.

  • 3. Vacuum Brazed Construction for Superior Durability

    • With vacuum brazing technology, the diamond layer adheres securely to the shank, enabling prolonged use in heavy-duty applications. Lasts ~50% longer* than non-vacuum brazed alternatives.

  • 4. Triangular Shank Design for Enhanced Stability

    • With a triangular shank (M14 thread), you can achieve secure grip in drills, reducing slippage and vibration compared to round-shank bits*. Ideal for professional and DIY use in demanding tasks.

  • 5. CE-Certified Safety & Versatility

    • Certified to CE standards, ensuring compliance with safety and quality regulations for both home and commercial use. Compatible with masonry, concrete, and tile applications, offering a reliable solution for diverse projects.

Supplier's note

  1. Technical Breakthroughs:

    • Diamond Coating: Triple the hardness of carbide bits, enabling 25% faster drilling in porcelain.
    • Vacuum Brazing: Ensures diamond grit adheres 40% stronger than standard methods, reducing chipping.
    • Triangular Shank: 30% more torque resistance than hexagonal shanks, preventing slippage in tough materials.

  2. Version Selection Guide:

    • Base Model: Ideal for home DIYers drilling small to medium tiles (≤35mm). Its CE certification and 20mm depth handle standard projects.
    • Advanced Model: Professionals working with thicker masonry (e.g., 60mm concrete) benefit from extended depth and 20% faster performance.
    • Pro Model: Commercial contractors drilling 100mm glass or 50mm porcelain gain unmatched durability and 25% speed over competitors. The Pro’s 50mm depth markings enable precise control in heavy-duty applications.

With the Pro’s 40% enhanced durability, users can tackle abrasive materials like granite without frequent bit replacement. Pair its 100mm diameter with the triangular shank’s stability to ensure flawless results in large-scale projects.
