They do what they are suppose to.

Cumplen con su función pero se desgastaron en solo uso bastante

While I haven't actually used these yet, so can't speak to their performance per se, I will say that this set is *very* nicely machined, so is very sharp, polished, and symmetrical, with absolutely no burrs, rough surfaces, chips, etc. Each solid carbide bit is packed in its own individual re-usable plastic tube. They at least *look* very good, indeed, and much better than several similar-priced Chinese-made end-mill sets I've seen up close. Let's hope they perform as good as they look; if so, they will be great value for the money!

product on time, works fine

This is my second time purchasing this product. The first time, I bought the 3/8” version, but I accidentally dropped it on a tile floor and chipped the cutting edge. This product is absolutely worth the price. It’s incredibly sharp, and using it to machine metal is extremely satisfying—watching the chips fly as it cuts through the metal is just awesome.
