Wet Diamond Core Drill for the drilling of mass concrete and reinforcing. Other specifications and sizes are available P.O.A. These cores provide very fast cuts with a long lifetime, the DTOX segments and crowns are completely Cobalt free making it safer for the operator and the environment.
Notes for wet drilling
These drills are designed to work with coolant. Insufficient water will shorten the drill life and can result in segment loss with brazed bits.
When drilling through reinforcement maintain coolant flow & keep steady pressure on the drill bit.
When using small diameter drills maintain a steady but not excessive pressure as they are not so robust as larger size drills
Ensure the rig is securely mounted and in good working order ensuring no excessive play in the rig.
