Designed for plumbing and electrical contractors drilling clean holes through cured concrete walls and floors, this 1-7/16" core bit delivers consistent performance on residential and commercial jobsites.

Diamond segments are laser-welded to the steel barrel for secure attachment under continuous drilling loads. Standard arbor connection fits most professional-grade core drilling rigs and handheld systems. This Husqvarna Professional tool handles concrete, block, and masonry materials where precise diameter holes are required for pipe runs, conduit, and mechanical penetrations. Built for trades running multiple holes per day who need reliable cutting performance and predictable wear rates.
