this thing breaks constantly. Absolutely junk. I'd love to see how bad the grade of "carbide" it is that they're using.

used to cut 5/8 thick HR steel, cut like butter, nice product and price.

This little corn cob cuts really well. It's small size allows for rough-milling in tight areas. It's carbide, so it should perform equally well in steel or aluminum. It is value-priced, so I feel comfortable exploring its limits...

Not durable, but works well for a while. Just what you’d expect for the price
