Global Leading Diamond Tool Manufacturer.
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.
