GRAPHITE timanttiporakruunu poratelineelle 58G540 122×450mm×11T

On a busy construction site, a plumber needs to run a 122 mm pipe through a reinforced concrete wall. With the GRAPHITE Diamond Hole Saw mounted on a 58G540 drilling rig, the job takes minutes, not hours. This segmented diamond core bit is built for professional wet drilling in concrete, reinforced concrete, masonry, and brick. The 450 mm working length allows deep cuts, while the 1 1/4" UNC thread ensures a secure fit on compatible core drilling machines. Eleven industrial diamond segments, brazed to a high-quality steel body, deliver fast cutting and long life. Water cooling is required to keep the bit cool and flush debris, preserving the diamonds and extending tool life. Whether you're installing ventilation, plumbing, or electrical conduits, this hole saw delivers clean, precise holes with minimal effort.
