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

These will cut through thick steel just fine at 45000 rpm, but they wear down fast, good quality cutting wheels though, better than many others out there.

These cut great! They last much longer than the non reinforced type, which sometimes can be seconds. They're much tougher and far less brittle. I will stick with the older old style manual mount type. It's the same disk without quick mount, they screw on disk. They are a much better value. Many more disks for much less cost. Same brand and quality. Is slight ease of use worth the cost? Lastly they cut cleanly, and can smooth sharp edges.

Get these, using high speed air pencil grinder and the special dremel chuck, magic. Cut off two Jeep JK rear axle bearing retainers and races using only 1.5 of these disks. Great for fine cuts or in tight spaces, last surprisingly long time. Great non slip chuck system as well.

Worked great for cutting off nail staples from hardwood flooring that was removed and repurposed for a craft project. Had thousands to remove and my dremel with these metal cutoff wheels worked perfectly.

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.

These are great cutting tools. I love the easy lock system. It works MUCH. better than anything else I've seen used. These cutting wheels are far less likely to explode than anything I've used otherwise. Be aware that some of the amazon shippers can get mixed with fake ones, so be sure that what you are getting is authentic.

Great for Hobby folks

Good value

Très souvent des imitations Chinoises mal sertie , mais ce produit est conforme et bien serti .

Useful set of metal cutting wheels. EZ lock is better than the default one with teh screw For cutting small things like bolts and screws, they work great. Even for deburring sharp edges, they are useful Will buy again when on sale
