Diamond Core Drill Bit Segments are high-performance, industrial-grade cutting components engineered for drilling reinforced concrete. Designed to be welded onto core drill bits ranging from 14mm to 500mm in diameter, these segments are the critical element that delivers speed, precision, and durability in demanding drilling applications. Manufactured with a specialized formula and high-grade diamonds, they ensure efficient wet cutting operations, making them the ideal choice for construction, plumbing, electrical, and coring contractors.

Product Description

Our diamond segments are precision-engineered blocks featuring a robust metal bond matrix embedded with high-concentration synthetic diamonds. As displayed in the product images, the segments exhibit a uniform, semi-cylindrical or block shape with a textured surface, indicative of the optimized diamond exposure. This design ensures consistent, aggressive cutting action and effective debris removal during wet drilling. The segments are produced in a range of precise sizes (e.g., 3x10mm, 24x4.5x10mm) to match specific drill bit diameters, guaranteeing optimal segment placement and performance for every hole size from small anchor holes to large-diameter core openings.

Key Features & Benefits

• Fast Cutting & Extended Service Life: Incorporates a high density of premium-grade synthetic diamonds within a specially formulated bond. This combination provides an aggressively sharp cutting edge for rapid penetration through concrete and rebar, while the controlled wear rate ensures exceptional segment longevity and reduces cost per meter drilled.

• Application-Specific Bond Design: The metal bond matrix is scientifically developed for the specific abrasiveness and composition of reinforced concrete. We offer different bond formulations to match varying concrete hardness and aggregate types, ensuring stable performance, predictable wear, and resistance to segment glazing or premature wear.

• Precision Engineering for Safety & Performance: Each segment is manufactured to exact dimensional tolerances, ensuring a perfect fit and secure welding onto the drill bit body. This precision minimizes vibration and run-out during operation, leading to safer, quieter, and more precise drilling with clean hole edges and no chipping or spalling.

• Optimized for Wet Cutting: Designed explicitly for wet use, these segments rely on water cooling to dissipate heat, reduce friction, and extend lifespan. The wet cutting process also suppresses dust, enhances diamond performance, and ensures faster, smoother drilling cycles, significantly reducing overall working time.

• Great Adaptability & Stable Performance: The segment's formula and structure provide excellent adaptability to various reinforced concrete conditions. They deliver consistent, reliable performance in both vertical and horizontal drilling applications, maintaining cutting speed and integrity throughout the segment's life.
