Core Bore Drill Bits - Supreme Silver Professional Wet Core Bit

Plumbing and electrical contractors drilling pipe and conduit penetrations through cured concrete walls will find this wet core bit handles the demanding work. The Supreme Silver Professional series from Diamond Products uses a silver-brazed segment design that maintains cutting speed in reinforced concrete and block. Water cooling through the bit extends segment life and controls dust on interior jobs where containment matters. The brazed construction holds segments secure under the torque and side load that comes with drilling at angles or in tight spaces. Works with standard core drill rigs for holes in foundation walls, mechanical rooms, and retrofit installations where clean, accurate penetrations are required. Built for drilling contractors and mechanical trades running multiple holes per job.
