These cutting wheels are cheap and perform superbly when used as advised. ([...])

I currently use these to cut aluminum alloy metal ferrules as well as certain plastics, such as those that make up ice coolers. I've broken cutting wheels because I've gone against these tips. With any high-powered tools, caution and scrutiny are always a necessity, especially for obtaining high performance. I've copied the 'Tips' section for those who decide not to follow the link.

Pros:

- Does exactly the following: Ideal for cutting, grooving and trimming all kinds of metal. May also be used on other materials-including thin wood, plastics and ceramics. Cut-off wheels make it easy to cut bolts or screws or make slots in rusted or stripped bolts and screws for removal with a screwdriver.

-Cheap

Cons:

-Fragile and can easily break when not used as advised.

User Tips

The cut-off wheel cuts only along its edge. Do not attempt to sand or cut curved holes with them. (I do this, but very carefully. Not recommended bc they do break if not carefully applied!)

Secure objects to a stable surface while working.

Hold the tool so that the wheel is at a perpendicular angle to the material being cut.

Keep a light touch, as the wheel will break under too much pressure. If chattering occurs, increase speed.

Plastics require very slow speeds, because they tend to melt at the contact point. Wood requires low speeds also, always experiment on a scrap first.

5.0 out of 5 stars Cuts Ductwork, February 1, 2011

By 

Ryan Triangle "Ryno" (O'Fallon IL) - See all my reviews

This review is from: Dremel 409 Cut-off Wheels .025" thick, 36 Pack (Tools & Home Improvement)

Does take some tecnique to get long life out of the discs like another poster mentioned. Just wanted to say that these discs work great on cutting ductwork. I saw what metal cutting shears do on ductwork and wanted a more precision cut for mounting my whole house humidifier and accessories.

Tip: I found that if I started the line and continued on the marked trail, the disc wore down realatively fast. My method in the end, for long disc life, was to use a "stitch-like" method for cutting the ductwork. So I'd start into the material until it cut through, the picked up the tool and started a new cut right next to the last cut. Hopefully that makes sense. Good luck.

This product for the cost was a steal as the cutting blades are usually around 2.00 dollars each and not a whole container for around 3.00.What a deal and they were not cheap knock offs.They performed excellently.
