REETAI-FOUR 10Pcs TCT Hole Saw Kit,Tungsten Carbide Tipped Hole Saw Set, Hole Cutter Heavy Duty for Stainless Steel.(5/8-2-1/8”).

Liked that all hole saws came in their own container,own “L” wrench and own drill bit.I used the 2 1/8 hole saw worked great

I knew these were going to be cheap, but not this cheap. They come with the worst pilot bits Ive ever seen. I snapped 3 pilot bits within the 1st few uses. After changing to better pilot bits now the carbide teeth are breaking off. This is the 1st week Ive used these bits with only being used on electrical panels which is thin steel. Buy something else

I am very impressed with these are you someone several projects way better than a hole saw

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.

I’ve only used a few of them. They worked well with 3/16” steel plate. They’ve had a little trouble with drilling bed rail (which is harder than standard steel).

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

Tooth broke the first time drilling through mild steel. The bit kept cutting which is why I didn’t give only 1 star.

The cutters have worked adequately for the hobbyist projects, but be careful to use the right RPM, pressure and some sort of cutting oil to keep the teeth from overheating. The only complaint is that its hard to tell if the teeth are the same depth or there is a lot of runout relative to the shaft.

Even if you use oil these scream on a low revolution drill press. they dont seem to bit into the metal very small shavings/chips. The kit itself is nice, spring loaded to push the metal plug out. They work just takes some time.

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
