• Best For: Wet coring 1-1/2-inch (38mm) holes for larger conduit bundles and small drain or condensate lines.
• Highlight: At 38mm the barrel clears enough bore to pass several small cables in one penetration instead of drilling two smaller holes.
• Expert Note: A 38mm core takes noticeably more rig thrust than the 32mm, so let the bit feed under its own weight rather than forcing it.
