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”).

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

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

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.

Does a great job. They are made for a drill press only. If you use a hand drill and drill like you normally would do with a hole saw you will break the teeth off of this type of hole saw. Glad I bought a full set. Jim

Great value and quality - would definitely purchase

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”

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

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

Cuts clean, punching holes.

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