  • 【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.
  • 【Professional Usage Instructions】To maximize service life, continuous water cooling is recommended. The water cooling system prevents overheating, reduces dust and noise, extends tool life, and improves cutting performance.
  • 【Parameter】2 1/2"/64mm, Drilling Depth: 15''/380mm, Thread Type: 1-1/4-7"", Total Length: 17.7''/450mm, Diamond Segment: 24 x 4.8 x 15mm
  • 【Wide Range of Application】This concrete core drill bit is specifically designed for wet drilling in concrete, reinforced concrete , exposed aggregate concrete, old concrete, fireclay brick, masonryIt is especially suitable for installation tasks of air conditioning, piping systems, and range hoods.
