Dremel EZ456B 1 1/2-Inch EZ Lock Rotary Tool Cut-Off Wheels- Rotary Tool Cutting Accessories, Perfect for Slicing Sheet Metal and Copper Pipe, 12 Pieces

I purchased these to make some small cuts in sheet aluminum and they worked great. The material I was making cuts in was 0.040" 2024 aluminum which is fairly hard as aluminum goes. These wheels cut through the material easy and showed only minimal wear, actually less then I had expected. The locking feature worked fine for me an is a lot easier then the ones that are held on with a tiny screw. So buy these with confidence that they will do what they say and not wear out quickly.

Appearance, Ease of Installation, Quality and Price/Value are excellent. No issues.

I like the new easy-lock system Dremel uses. I think the wheels break off a little more easily than in the past, but that's outweighed by how easy it is to replace them. I find that if I just reduce the speed a bit and work a little more carefully, these last long enough for what I do.

Funny how something so small can work so incredibly well and really cut through just about anything can cost so little. I honestly can't think of any fabricator who doesn't have these in their shop, as when you're in bind and the area to work within is super cramped, these are an absolute life saver!

Love these cutoff wheels! I especially appreciate the quick change feature; before I discovered these, it seems that I spent my valuable time unscrewing the top of the mandrel and painstakingly threading the tiny screw through the new cutoff wheel, and heaven forbid if you tighten it too much. The wheel would crack, and then you start all over again. I find the method of attachment to be easy and quick. Then why the 4 star review, instead of 5? Although they are a pleasure to use and enable me to do my work better and quicker, there are a few “flaws” that could be improved upon. Dremel, take heed…For a “heavy duty” cutoff wheel, these things are snowflakes. Granted, the wheel itself is capable of most things asked of it, but the fittings are unbelievably delicate. If the prongs are not getting loose, the entire circular fitting attached to the prongs often decides to shear off of the wheel, rendering it useless. I am extra careful, well remembering how many of these things I’ve had to throw away because of their delicacy, but the fittings will still disengage with very little provocation. And heaven forbid you try to carry around your Dremel tool with the wheel assembly still in it. No matter how careful you are with it, when you reach for it, you will find a loose wheel spinning around those brass fittings. I hate that I have the unbelievably great cordless Dremel tool (ok, I have 2 of them-one should always have backup) and its versatility is diminished that one must handle those wheels with kid gloves. Very frustrating, as these things are not cheap. Still, for my purposes, I’ve not found anything better, so I continue to buy and use them. This product could be a solid 5 star item, if Dremel would just address the attachment aspect.

Excellent product don't buy cheap imitations you get what you pay for

Used in the past and loved the easy setup. I just wish they were more affordable. But all and all the products work well.

Easy load but a little high on the price
