  • 【High-performance Drilling Capability】Our core drill bits boast a cobalt content 4.5 times higher than that of standard core bits (which only contain 10% cobalt). This significantly enhances the hardness of the base material—reaching HRC 70, a level close to carbide hardness—thereby reducing wear, boosting heat resistance, and doubling the service life compared to conventional drill bits.
  • 【Industrial-grade Segments】Engineered for high-speed cutting of reinforced concrete with a diameter of ≤25mm, our diamond core drill bit feature a sturdy structure paired with advanced laser welding technology. This design effectively prevents blade breakage, ensuring reliable performance in tough industrial applications.
  • 【Versatile Compatibility】Equipped with two adapters: a hex adapter for heavy-duty, high-torque drilling machines and an SDS Plus adapter for small to medium-sized, lightweight drilling machines. This broad compatibility ensures flexibility and applicability across various drilling scenarios (note: do not use in hammer mode).
  • 【Technical Parameters】Diameter: 1"/25.4mm; Drilling Depth: 11"/279.4mm; Thread Type: 5/8"-11; Total Length: 12"/304.8mm; Diamond Segment Height: 10mm.
  • 【Wide Application Range】Specifically designed for drilling through a variety of materials, including concrete, red bricks, tiled masonry, cinder block walls, asphalt, and rock. It is particularly ideal for installation tasks such as air conditioning, piping systems, and range hoods.
