      The EZ Lock Mandrel works as advertised. It allows for very quick and easy replacement of cutting, sanding and buffing heads, No tools are required to change heads once the mandrel is mounted in the Dremel tool. It is a big improvement over the screw head mandrel which requires a small screw to be removed from the top of the mandrel each time you want to change or replace a head. The only down side is that the mounting bracket which fits the cutting,sanding or buffing head to the mandrel tends to break away from the head too often. I recently completed a project using the EZ Lock Cutting heads designed for plastic to cut a piece of plexiglass to make a 32" round cover for a coffee table. The tool worked brilliantly the edges cleaned up with a light buff from the EZ Lock buffing pads. The problem was that I went through at least 6 cutting heads due to the fact that the metal bracket meant to mount the cutting head to the EZ Lock Mandrel kept separating from the head, rendering the cutting wheel useless. I finally switched back to the traditional mandrel and finished the job without having to change cutting heads. Note that the EZ Lock Cutting Wheels did not wear down and still had plenty of life remaining - they just broke away from the mount. This could have been because I was using them to cut a radius which caused tension on the mount, but I did not force them and they were cutting fine. If you are making straight cuts, and will have to change heads, this tool is worth the investment. Also note, the EZ Lock Mandrel will only work with heads that are designated as EZ Lock. You will not be able to use the EZ Lock Mandrel with other manufacturer's tool heads as you can with the standard mandrel. The only other downside of the EZ Lock line up is the cost. The replacement tool heads are about three times more expensive that their standard mandrel counterparts, but you pay for convenience.

      I just bought a new Dremel after leaving mine behind in one crazy heck of a move. When I bought new heads for it, I realized some of them required the EZ lock mandrel to be used--the best ones did. If you buy a Dremel set with several tools, this may already come with it but my new Dremel did not have it. And really, it's something you'll want.

      This allows you to change out the heads on your Dremel in a snap--no special tools, far less time. And that can be a huge bonus if you are working on something creative, which I do all the time with my Dremel tool. Heck, I use it for everything from cutting spurs grown too long on my rooster (he doesn't feel it, but he sure feels inconvenience in walking when they are too long!), to doing creative cuts in wood, to doing fast trims when putting reclaimed wood up on a wall, and more.

      Quite frankly, I use it quite a bit. And time is money, so in my mind this pays for itself in one day of Dremel use. Not only that, but in my opinion Dremel is moving towards heads that only use this--some of the best ones can't be used without it so it is simply not only a better way of using the Dremel, but for many of us, a must-have.

      Simple. Easy. Saves Time.

      Enough said with that alone.

      Mi Dremel originalmente trae 3 diferentes mandriles (diametros diferentes), es necesario para usar diferentes accesorios, pero la mayoría de estos últimos son discos y todos utilizan el tamaño más grande.

      Este aditamento reemplaza a esa pieza, siendo más grande y robusto, creo que queda mejor. Además claro que es más fácil instalar los discos.
