  • Engineered with pointed diamond segments for ultra sharp and aggressive cutting. Starts holes faster and drills efficiently through reinforced concrete, brick and stone.
  • Wet use only. Water cooling reduces heat and dust, protects diamond segments and extends service life. Not designed for dry drilling
  • Built for rebar concrete and hard masonry. High-density diamond matrix resists segment loss and cracking under heavy-duty wet drilling.
  • 15.7" (400mm) drilling depth with 17.7" (450mm) overall length, ideal for thick concrete walls, stone blocks and deep penetration tasks.
  • Standard 1-1/4"-7 UNC thread fits most core drilling rigs and machines. Stable connection ensures accurate drilling and safer operation.
