Dremel 1 in. EZ-Lock Mandrel

I've been using EZ Lock for a few years and think it's great. With the screw-type mandrels, there have been a lot of times I didn't bother to use the rotary tool just because of the hassle of the set-up, particularly for a quick job, but with how easy and quick it is to use the EZ Lock mandrels, I get more usage out of my rotary tool (current one is a Dremel 4300) than without EZ Lock. My only complaint is that the spring is a part that wears and it holds the discs with less tension over time. But, the trade-off of a much easier to use mandrel is worth it. Especially when it comes to some of the stuff I do with my Dremel, I'm swapping accessories around some, so being able to quickly change between a cutting disc to a sanding disc or to a different sanding grit or from a grinding disc to sanding disc when I've been doing work on small metal parts ... So, I can live with the spring wearing out. I just hadn't really considered it when I got my first EZ Lock mandrel. And, while there is some loss of tension with initial wear-in of the spring, after it gets to that point, it holds pretty steady for a while, so it's not like I'm going through a lot of these. Overall, I'm sticking with the EZ Lock system and don't bother with the older style anymore. For me, it's one of the small things that makes a big difference.

very good product easy to install and use would purchase it to have a second one, thank you for sending it to me. it is a quality mandrel. so nice to have Dremel as a supplier. Another time saving device

The Dremel EZ Lock Mandrel (EZ402) makes switching Dremel attachments quite fast and easy when EZ Lock attachments are used. It does take a little practice to find a good grip to pull back the lock, but once this is mastered it becomes quite easy.

not so easy for me to do the small movements with arthritis in my hands but it was easier after the first feew tries. Good idea just have to get used to it. Dremel sent this item to me free of charge to try for them. I like hte idea just wish it was easier to use.
