Rohrleger: Sehr gutes Preis/Leistungsverhältnis. Bei sachgemäßer Anwendung halten die Tools wirklich lange
(Gute Kühlung und entsprchende Drehzahl vorausgesetzt). Für den Handwerkerbereich durchaus
geeignet (nicht für Massenfertigung!). Klare Weiterempfehlung von Mir.

Charles Clark: I have used these bits a few times now and they BITE! I have had no issues so far with them cutting. They are sharp and accurate. I used these to cut out slam locks in aluminum. I have not noticed any teeth breaking off during my use so far. It cuts through metal like butter. I recommend this product for those looking for a good metal hole saw.

BrentBrent: I think these would be fine for mild steel, especially if used in a drill press.

I was able to cut a 2" hole in an old piece of equipment. The part I cut out had been welded before. The welds are, of course, variable hardness. When the teeth impacted the welds some teeth -- then most teeth broke off.

It was a trooper though, the two last remaining teeth finally made it through all the way. Given the low cost, and difficult task, I think it performed well even if it destroyed itself in the doing.

Caveats:
1) I used a handheld drill and when the teeth caught, it whipped around and twisted (ask my wrists!). This violent action may have broken teeth off. If you use a drill press you may see better results.
2) I was cutting through old welds -- which were rough until it got started, and can be very hard in places. This was not an easy cut I asked it to do.
3) Since I was drilling out an old pin hole (see photo) I used a wooden plug pounded into the old hole so the center drill bit could have something to center the hole saw. If I had used a steel plug, the center drill drilling through the steel would have slowed down the feed rate and may have protected...

Handyhusband01: Been watching videos from various Maker's on You-Tube and many of the Asian and European Makers use this type of hole saw when fabricating welded metal based projects. So I decided to try. The set I chose had it's own carrying case for slightly extra cost which keeps them organized and prevents contact to each other which is important. I have used up to 1" with a hand drill - no issues and controllable. For larger I use a drill press or the Bridgeport. I also have a Deming type twist drill set and drilling 1" with a cordless drill sometimes tears out of my hand. So this type hole saw is a welcome addition to the shop.

Thomas: Diese Lochsägen sind kein Profiwerkzeug aber für den Preis eigentlich OK. Allerdings muss man sie bei kleiner Drehzahl und ohne großen Druck sowie mit Schneideöl benutzen. Wichtig ist auch das Werkstück gut einzuspannen. Ich denke wenn man dies befolgt dann sind die Lochsägen nicht beim ersten Mal benutzen kaputt. Ansonsten hat man ja die Möglichkeit diese von Fein zu kaufen ,allerdings bekommt man ums gleiche Geld nur ein Werkzeug mit 30 mm.
