Our laser-welded segmented diamond bits (heavy-duty engineering core bits featuring precision CNC-machined steel barrels and laser-welded diamond segments) are engineered specifically for high-impact, fast, and continuous core drilling through heavily reinforced materials. Utilizing high-energy laser welding technology, the diamond segments are metallurgical melted directly to the alloy steel core, delivering extreme joint strength, superior thermal safety, and complete segment detachment prevention during heavy dry or wet drilling operations.
They are extensively utilized across civil engineering, road construction, building renovation, and heavy stone processing sectors:
Reinforced Concrete & Rebar Cutting: Essential for penetrating heavily reinforced concrete walls, bridges, foundation piles, and steel rebar structures.
Asphalt & Pavement Core Sampling: Ideal for road construction testing, asphalt pavement coring, utility line installations, and airport runway maintenance.
Granite, Marble & Hard Masonry: Applied in heavy stone fabrication for deep hole drilling, anchor installations, and plumbing pass-throughs in dense natural stone.
Building Infrastructure & HVAC Ducting: Perfect for core drilling large-diameter openings for AC ductwork, plumbing risers, and electrical conduits.
High-Strength Laser Welded Joint: Laser beam welding fuses segments onto the steel barrel with unmatched bond strength, completely eliminating segment loss even during dry drilling or accidental rebar impacts.
Precision CNC Machined Heavy Barrel: Engineered with seamless alloy steel barrels turned and threaded on multi-axis CNC lathes (1-1/4″-7 UNC, M14, 5/8″-11, or custom connections) to ensure exact concentricity (+/-0.005 mm) and zero drill wobble.
Aggressive Diamond Matrix Formula: Formulated with high-grade industrial diamond grains and premium metal bond matrixes, providing rapid penetration speeds and exceptional wear resistance in hard aggregates.
Dry & Wet Drilling Flexibility: Outstanding thermal resistance allows safe dry drilling where water coolant is restricted, while also delivering maximum tool life under wet drilling conditions.
Versatile Dimensions & Custom Threads: Fully customizable in core diameters (18 mm to 350+ mm), drilling depths, barrel wall thicknesses, thread standards, and custom laser markings.
