The DeWalt DW1803 7/16-Inch Quick Change Mandrel is used with a 1/2 inch or larger chuck and 1-1/4- to 2-1/8 inch hole saw. The primary application of a hole saw is to install pipe, copper tubing, or PVC. These saws can be used to cut a round hole in either wood or metal, and when used with the proper mandrel, they will fit most drills.

I love the quick change mechanism on this shank. It's very secure and makes quick changing of hole saws very easy.

I have utilized several manufacturer's hole saw mandrels performing electrical work, routinely drilling light guage steel, aluminum, bronze, silicon bronze, stainless steel, plastics, and wood. Some mandrels are difficult to change from one size hole saw to the next because of inexpensive hex set screws stripping. Soooo aggrevating! Others, made like the Dewalt mandrel compare with an exposed spring release, but the spring being exposed, many times shavings interfere, it can be damaged, ruining the spring and making it difficult to unscew the locknut. I have found the Dewalt Mandrel to be easy and durable. Of course, drilling with hole saws can be dangerous and one should always be cautious, not agressive, allowing the saw to perform at it's own rate, especially when penetrating a variety of materials. I have yet to have this mandrel break or cause problems. It has proven to be very reliable, and I have been utilizing it for almost a year, drilling hundreds of holes (2-3/8" - 4-1/2"). I am sure, as with most attachments for power tools, even with the best of care, they will eventually have to be replaced. But, at this rate, my DeWalt Mandrel has paid for itself several times and has proven to be very effective and safe. "SAFETY FIRST"

Appears to be a well built product. I've had frustrations with the quick change collar releasing while using it and results in a stuck mandrel in the hole saw. Today, after many years of use, one of the two pins in the quick connect broke off. I'm confused how it managed it, since the engineering would make one think it would be impossible.
