Milwaukee core bit extensions let you drill through thicker materials than a standard core bit can reach on its own. Adding an extension gives you an extra 7-1/2 in. of drilling depth, so you can core all the way through thick walls, slabs, and foundations without stopping short.
Great Lakes Power Tools carries Milwaukee heavy-duty core bit extensions sized to fit Milwaukee diamond core bits and the adapters that go with them. Whether you're coring deep concrete, block, or masonry for plumbing, electrical, or HVAC runs, an extension gives you the reach to finish the hole.
