  • 【High-performance Drilling】Our core bits have 4.5 times the cobalt content of standard drill bits (which contain only 10% cobalt), increasing the hardness of the base material (hardness HRC 70, close to carbide hardness), reducing wear, enhancing heat stability, and thus extending the lifespan of the drill bit to twice that of regular drill bits.
  • 【Industrial-grade Segment】High-speed cutting of reinforced concrete with a diameter ≤25mm; the robust structure and innovative laser welding technology prevent blade breakage.
  • 【Versatile Compatibility】Includes two adapters: a hex adapter for heavier & high-torque drilling machines and an SDS Plus adapter for smaller & lighter to medium drilling machines. This ensures broad applicability and flexibility in various drilling scenarios (do not use in hammer mode).
  • 【Parameter】2 1/2"/63.5mm, Drilling Depth: 11''/279.4mm, Thread Type: 5/8"-11, Total Length: 12''/304.8mm, Diamond Segment Height: 10mm
  • 【Wide Range of Application】This concrete core drill bit is specifically designed for drilling through various materials, including concrete, red bricks, tiled masonry, slag brick walls, asphalt, and rock. It is especially suitable for installation tasks of air conditioning, piping systems, and range hoods.
