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”).

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

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

Advertise as imperial but they are metric

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

No son. Tan eficientes como lo indican dañan el área al agujerar y no son lo suficiente efectivas para hacer bien el trabajo que están echas.

Great value and quality - would definitely purchase

Drills bits shattered as they touched cold steal, but the outer cutters remain strong

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.

Like them for drilling big holes quickly in mild steel up to 1 inch thick

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).
