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"
