This product was delivered by UPS to wrong address... Both times a shipper used UPS over the last year, package was dropped off at a wrong address. Spent a day trying to locate package and UPS was no help. Going to request any shipper using UPS that they give to another shipper...

I have used it on 1/4 inch thick structural aluminum. This cut like butter. This was also a good value.

We used this to cut a hole in a stainless steel sink... worked great! Didn't comment on longevity as I've only used it once but it shows to wear after that one use.One tip: drill a pilot hole first then put this in the pilot hole. Also, if you're going through stainless steel, go at the highest RPM and bounce it up and down. it'll get through without binding.

J'ai acheter ce produit pour faire 4 trous dans un "hitch" de voiture de 2 pouces en acier. Une fois le trou pilote partie, il a fait un trous de 5/16 de pouces en quelques secondes. Je suis très impressionné. Il marchait aussi bien au quatrième trous qu'au premier.
