Johnson Tools Hot sale 6 types of Diamond Drilling Segment for Core Drill Bit Reinforced Concrete Core Drilling

Customize your drilling performance with Johnson Tools' 6-Type Diamond Segment Series. We understand that different aggregates and steel reinforcement levels require different cutting characteristics. That's why we offer 6 specialized segment shapes—including Turbo, Roof Top, and Great Wall—designed to optimize speed, life, and starting ease when drilling through Heavily Reinforced Concrete. Perfect for professional Retipping workshops and contractors who weld their own bits.

Why Choose Our 6 Segment Types?

  • 1. Roof Top (V-Shape): The "Pointed" design reduces contact area for Instant Starting. It centers the bit immediately, preventing the tool from wandering or vibrating on the first cut.

  • 2. Turbo (Grooved): Features side grooves to flush out slurry and reduce friction. Ideal for Deep Drilling and high-speed cutting in hard concrete.

  • 3. Great Wall / Ladder: A corrugated design that provides aggressive biting edges. Excellent for cutting through Hard Aggregates (like Flint or River Rock).

  • 4. Sandwich: Constructed with a softer center and harder sides. This ensures the segment wears evenly ("concave" wear) to keep the diamonds exposed and razor-sharp at all times.

  • 5. Normal (Flat): The classic, massive segment shape. Offers the maximum diamond volume for the Longest Lifespan in general masonry.

  • 6. Mesh / Dimple: Reduces side drag significantly, perfect for lower-power drill motors or drilling with limited water flow.

Technical Specifications:

  • Application: Reinforced Concrete, Cured Concrete, Brick.

  • Welding Method: High-Frequency Silver Brazing (Recommended for Retipping).

  • Dimensions: Length 24mm; Height 10mm/12mm; Width (Matched to your barrel thickness).

  • Bond: Cobalt-based matrix for cutting steel rebar.

    1
    Q1: Which shape is best for drilling Rebar?
    A: The Turbo or Sandwich segments are typically best for rebar. The Turbo flushes metal shavings out quickly, while the Sandwich design stays sharp even when cutting through ductile steel.
    2
    Q2: Why use "Roof Top" segments?
    A: "Roof Top" segments are essential for a New Bit. If you use flat segments, it takes a long time to grind them into the correct curve, and the bit may wobble. Roof Top segments start cutting immediately.
    3
    Q3: Can I mix different shapes on one bit?
    A: Yes! Some professionals use a "Hybrid" setup. For example, using Roof Top segments to start the hole and Turbo segments for the rest of the ring to maximize speed and cooling.
    4
    Q4: How do I attach these segments?
    A: These are designed for High-Frequency Induction Brazing using Silver Solder and Flux. This is the standard method for retipping used core drill barrels.
