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”).

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

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

Have not used any of them yet. Believe me if they are a cheap set of hole saws , I will let you know.

First, they come in a plastic box but they wont fit back into the box once you put the drill bit in them. Thats ok because the boxes are brittle and brake up about the 2nd or 3rd time you open them. Second, hole size is not very accurate, about +- 1-1/2mm off. If you need imperial sizes, they are off even more. That said, they drill a very nice hole in 3/8 in. Mild steel. Very nice hole saw kit. I would recommend this set.

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).

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.

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

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

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

Okay for the price. Although the description states the 30mm bit is 1-1/8” (1.125”) when actually 30mm is 1.181” which is too large for a trade size 3/4”
