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

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

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.

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

Drilled one hole in 304 stainless 16 gauge tubing using the 35mm. It made the hole but no teeth left. Not sure about these bits yet. Update, drilled 18 gauge mild steel.... no teeth, even used oil. On aluminum they make great holes.

Used em to cut through 1/4 aluminum. Went through cleanly, like butter.

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

Muy confiable

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.

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.
