Review on 🔄 Greenlee 645-011 4" Change Through by Carl Durant

These quick change mandrels are great, especially on big jobs when the saw becomes dull or breaks. Replacing the saw is completely hassle-free as you don't have to remove the mandrel to remove the saw. Simply turn the saw counter-clockwise, remove and replace with a new one. No hex keys fall out or tighten, no screwdrivers needed. Just a glove for a fairly warm saw to change into.
