Manufactured with premium industrial diamonds and advanced laser welding technology, these drill bits are ideal for creating clean, accurate holes in reinforced concrete, asphalt, masonry, brick, granite, and other tough building materials.The laser welded core drill bit process fuses each diamond segment securely to the steel barrel, ensuring superior bonding strength and preventing segment loss, even under heavy-duty drilling conditions. This guarantees long service life, stable performance, and consistent cutting speed for both wet and dry drilling applications.Available in a wide range of diameters and segment designs, our diamond core drill bits meet the needs of various construction projects, from plumbing and electrical installations to structural anchoring and roadwork. Soft, medium, and hard bond options allow contractors to choose the right bit for different material hardness levels, ensuring maximum efficiency and cost-effectiveness on the jobsite.To maintain the highest quality standards, every concrete core bit undergoes strict inspection procedures, including segment hardness testing, welding strength verification, barrel quality checks, and high-speed balance testing. This guarantees that each tool delivers safe, smooth, and vibration-free drilling performance.Contractors around the world rely on our core drilling tools for their reliability, precision, and adaptability. Whether you are cutting through reinforced concrete walls, drilling deep cores in floors, or creating openings for utilities, our laser welded diamond core drill bits are designed to save time, reduce operator fatigue, and deliver professional results every time.Choose our laser welded core drill bits for your next project and experience the perfect combination of cutting power, durability, and safety in one professional-grade drilling solution.Detailed PhotoSpecificationDiameterSegment SizeSegment NumberValid LengthConnection?20Crown Segment1450mmUNC 1-1/4"-7?22Crown Segment1450mmUNC 1-1/4"-7?2512mm*3.5mm*9mm3450mmUNC 1-1/4"-7?2812mm*3.5mm*9mm4450mmUNC 1-1/4"-7?3216mm*3.5mm*9mm4450mmUNC 1-1/4"-7?3616mm*3.5mm*9mm4450mmUNC 1-1/4"-7?3816mm*3.5mm*9mm4450mmUNC 1-1/4"-7?4216mm*3.5mm*9mm5450mmUNC 1-1/4"-7?4724mm*3.5mm*10mm5450mmUNC 1-1/4"-7?5224mm*3.5mm*10mm5450mmUNC 1-1/4"-7?5724mm*3.5mm*10mm5450mmUNC 1-1/4"-7?6224mm*3.5mm*10mm6450mmUNC 1-1/4"-7?6724mm*3.5mm*10mm6450mmUNC 1-1/4"-7?7224mm*3.5mm*10mm7450mmUNC 1-1/4"-7?7724mm*3.5mm*10mm7450mmUNC 1-1/4"-7?8224mm*3.5mm*10mm8450mmUNC 1-1/4"-7?9224mm*3.5mm*10mm8450mmUNC 1-1/4"-7?10224mm*3.5mm*10mm9450mmUNC 1-1/4"-7?10724mm*3.5mm*10mm9450mmUNC 1-1/4"-7?11224mm*3.5mm*10mm10450mmUNC 1-1/4"-7?11724mm*3.5mm*10mm10450mmUNC 1-1/4"-7?12224mm*3.5mm*10mm10450mmUNC 1-1/4"-7?12724mm*3.5mm*10mm10450mmUNC 1-1/4"-7?13224mm*3.5mm*10mm11450mmUNC 1-1/4"-7?14224mm*3.5mm*10mm11450mmUNC 1-1/4"-7?15224mm*4.0mm*10mm12450mmUNC 1-1/4"-7?16224mm*4.0mm*10mm12450mmUNC 1-1/4"-7?17224mm*4.0mm*10mm13450mmUNC 1-1/4"-7?18224mm*4.0mm*10mm13450mmUNC 1-1/4"-7?20024mm*4.0mm*10mm15450mmUNC 1-1/4"-7?22524mm*4.0mm*10mm16450mmUNC 1-1/4"-7?25024mm*4.0mm*10mm17450mmUNC 1-1/4"-7?27524mm*4.0mm*10mm19450mmUNC 1-1/4"-7?30024mm*4.5mm*10mm21450mmUNC 1-1/4"-7?35024mm*4.5mm*10mm23450mmUNC 1-1/4"-7?40024mm*4.5mm*10mm25450mmUNC 1-1/4"-7Available Segment ShapesMore Core drill bit segment shapesWe produce wide range of core drill bit segments with different shapes, we can also do customized production as per customer's request..Quality Control And InspectionInspect the welding strengthWelding strength is critical for the safety and durability of a laser welded core drill bit. Using advanced laser welding technology, we bond each diamond segment firmly to the steel barrel. After welding, every diamond core drill bit is inspected with stress and pull tests to ensure segments cannot detach during heavy-duty drilling. This prevents accidents, downtime, and tool failure. By guaranteeing welding strength, our concrete core bits perform safely and consistently under both wet and dry drilling conditions. Contractors can rely on our core drilling tools for secure segment bonding and stable performance in demanding applications.Inspect the hardness of the segmentsThe diamond segment is the key cutting part of every laser welded diamond core drill bit. To guarantee efficiency and durability, we carefully test each segment's hardness before production. Segments that are too soft wear quickly, while those that are too hard can slow cutting speed. Our inspection ensures the diamond core drill bit delivers the right balance between cutting aggressiveness and long service life. This means faster drilling, consistent performance, and lower replacement costs for contractors. With strict hardness testing, our concrete core bits are reliable tools for a wide range of materials, from reinforced concrete to masonry.Inspect the core drill barrelsThe drill barrel provides strength and stability to a diamond core drill bit. Each barrel is inspected for thickness, roundness, and material quality before use. A poor-quality barrel may deform, wobble, or overheat during drilling, reducing tool life and accuracy. Our inspection process ensures the barrels meet high standards for dimensional accuracy and durability. With strong and precise barrels, our laser welded diamond core bits maintain smooth drilling, stable alignment, and long service life. Contractors using our concrete core bits can work confidently, knowing each tool is built with a reliable and carefully inspected barrel.Do the dynamic balancing test on drill barrelsProper balance is essential for safe and efficient drilling. Each diamond core drill bit is tested on high-speed machines to check its balance. Unbalanced tools cause vibration, reduce accuracy, and increase wear on both the drill and machine. By inspecting and correcting balance, we ensure smooth and stable drilling with less operator fatigue. Balanced laser welded core drill bits cut more efficiently, generate less heat, and deliver cleaner holes in reinforced concrete, masonry, and stone. This inspection guarantees that every concrete core bit provides professional contractors with reliable, vibration-free performance.Company ProfilePro Diamond Tools Manufacturer In ChinaFounded in 2017, Diacutex Diamond Tool is a professional manufacturer and exporter of diamond cutting and grinding tools.
