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”).

These are the cheapest made junk you’ll ever buy, please save your money and buy a quality set! I am a professional machinist so I know what lubricants, coolants, cut rates and so on to use I do this day in and day out and the first bit I used lasted 4.5 seconds before it sheered in half by twisting the shaft right off!

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.

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.

I disliked that they were metric

Great for plastic, it wont go through metals like advertised, would not buy again

Great value and quality - would definitely purchase

Only used 4 so far and 2 of them didnt make it through 6 holes each and the teeth came off

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.

Took several bit to get through concrete.

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
