Review on Effortlessly hitch and cut with Starrett XA10 Quick Hitch Carbide Tipped by Dustin Keller

This arbor is good for concrete. I use an old nail to make a groove where I want to drill. This eliminates the "walk" that a drill might want to do when you first start drilling. But it drills through concrete easily. When attaching your hole saw, always make sure it is secure and you should be able to get the job done fairly quickly.
