Review on 🔪 Lenox Tools 1779802 Arbor 4 Inch: Professional-Grade Cutting Efficiency for Precision Jobs by Dustin Woodrow

It took me a second to figure it out as there were no instructions but once I did it worked/fitted perfectly. Unfortunately I didn't pay attention to the size of the shank because it didn't fit the portable unchucked drill I was planning to use. For this drill I had to break out a large electric drill. It's fine, but make sure you know the size of your drill bit before buying. Still get 5 stars!
