Not sure how well the are for stainless but itll cut mild steel with ease

Hey I was cutting a 11/16 hole in. A piece of 1/8” Thike metal and it broke

Es lo mejor en herramienta

Was pleasantly surprised when i first opened them, but the first time I used these bits to cut a hole in a piece of metal, all the carbide cutters sheared off. What a waste

Everyone of them broke on me at our 1st job of the day . I had to buy another set . The customer service was pretty good

This item has proved to be used for many occasions when needing to make a hole for anything all the teeth on the circular saw does not appear to be sharpened enough to immediately pierce through metal eventually, after some time I was able to break through the metal needed access to still for the price I would recommend to anyone

Does a great job. They are made for a drill press only. If you use a hand drill and drill like you normally would do with a hole saw you will break the teeth off of this type of hole saw. Glad I bought a full set. Jim

The drill bits have this nasty habit of unscrewing with use. If everything holds together these drill bits work fine on light weight metal studs. If you are drilling through the old thicker metal studs you will need an impact drill in addition to this item.

These hole saws are fairly tough but beware of a few issues. First the Pilot drill bits are much to hard and brittle and under the load of drilling a larger hole can break easily. The other issue is that since these saws use welded on carbide chips, they are fairly wide and therefore cut a wide kerf and means the drill needs to be pretty heavy. In metal the saws also like to grab in material so be careful. This is also when the bit usually gets broke. All in all the price is right as long as you are aware of limits.

Drilled one hole in 304 stainless 16 gauge tubing using the 35mm. It made the hole but no teeth left. Not sure about these bits yet. Update, drilled 18 gauge mild steel.... no teeth, even used oil. On aluminum they make great holes.
