The Quick Mandrel, developed by a cabinetmaker, has a new quick-release system that allows you to easily lock and quickly release your hole saw. Line up the pins and push into place with a simple twist to lock your hole saw. No screws, no threads, as fast as changing a bit in your screw gun!
The shank on the quick mandrel is ~7/16". Please make sure your drill chuck can accept this size. 3/8" drill chucks will not work with this product. Most drills will have a 1/2" chuck, but please check yours before ordering.
