So I've bought several different sizes of these and they work really great! Mostly cutting thinner stainless with them, and doing so, they cut thru the stainless like a hot knife thru butter. I've only had one failure, but I blame myself on that one for using a hand drill on exhaust at a terrible angle on an elbow. If you're using these in a tubing notcher or a drill press where you can control your feed and pressure, they should last a very long time.

I used this saw to cut through a stainless steel kitchen sink. It worked just fine, with good results. I don’t know how long lasting it is, since I’ve used it only once. But no problem so far.

This hole saw and the pilot bit are well made I believe, because ultimately it made the hole and didn’t struggle to make the cut in 16 gauge of stainless steel. However my reason for one less star is that the pilot bit broke when it cleared the material and the main saw engaged to cut. As I’m not an experienced machinist, I’m not sure if it’s my fault - it’s a hand held drill and I should have anticipated the twisting force as the main bit engaged. But then most people who buy this are DIY’ers and will probably do it for first time. I appreciate if the manufacture included this warning to look out, or even better if they can add additional pilot bit for a marginally increased price. (I couldn’t continue to drill and succeed if I didn’t have a second hole saw of same brand in different size that had its own pilot bit). As a tip for others, use caulking to build a dam for your oil or water for cooling the bit and material (see picture)

Good for cutting metal, not so good for wood ,tends to clog.

Worked well when used in a mill at low speed to drill through 5/8” mild steel plate. Would stop cutting and then had to stop and clean shavings several times during process. But still sharp at the end of the cut.

I was impressed how this 2 in TCT carbide tipped hole say cut my 3 in thick counter for dropping my computer cables. It handled the thickness easily but you must go slow and vacuum the dust about every 3/4 in. of cutting and let the blade cool down.I got a smooth clean cut . A good idea is to wire brush the carbide tips after each cut it helps keep the hole saw in optimal cutting condition. Good design with above average cutting speed compared to other hole saws.

Buy two if you have to make more than 3 holes. After the third hole punching through 1/8 inch steel it caught the steel and stripped all the cutting bits off. Prior to that cut great! Luckily I suspected something like this might happen and ordered 2 of these. Got all 6 holes drilled out np.

Svolge egregiamente la sua funzione.

Das Preis Leistung Verhältnis ist sehr gut Der zentrierbohrer ist Tic Tin beschichtet Der Lochbohrer hat Hartmetallzähne sehr langlebig Sehr gut ich würde den Lochboherer jederzeit wieder nehmen Ich bearbeite hauptsächlich aluminium sehr gut geeignet

ハイエースにオルタネーターチャージャー（走行充電器）を付けるため、配線用の穴あけに使用しました。ど素人のため、他商品と比較できませんが、ど素人の私でも穴あけできたので、良い商品なのでは…と思ってます。プロの方にはどうか分かりませんが、DIYで利用するには良い商品かと思います。

Tried to use this on a piece of Maple about 20mm thick. It produced a very very fine sawdust, but after 10 minutes it had only managed to go into the wood about 1mm. Pressing harder, my drill press stalled. I don’t understand how other reviews had success drilling aluminium and steel !
