Two Neo-40 magnets embedded in the hex shank secure the reamer inside the impact socket, significantly reducing the risk of the tool falling out during use at height. Designed for use with air impact wrenches, these reamers are ideal for enlarging and aligning holes in structural steel assemblies, bridge erection, truck and trailer frames, and ship construction.

The tool also meets OSHA 29CFR Part 1926.759 for falling objects protection, which standard construction reamers do not address.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What drive tool is this reamer designed to be used with?\u003c\/strong\u003e\u003cbr\u003eA: The hex nut shank is designed for use with impact wrenches, including air impact tools.
