½" BSP Male thread Wet Diamond Core Drill| Kern-Deudiam | 12mm - 42mm dia. x 300mm E/L
Wet 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
- Make sure that the rig is securely mounted and in good working order ensuring no excessive play in the rig.
