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”).

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

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!

Everyone of them broke on me at our 1st job of the day . I had to buy another set . The customer service was pretty good

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”

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.

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

This product made it 3 holes before failure. All teeth are destroyed. I know these are vheep but they are trash. Hols look like they were cut with normal holesaw. Do not waste time or money on these.

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

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

Works great sharp and cuts good through stainless steel 16 gauge up to 3/16 that I used them on. Wish they would co e in a sturdy case. Only individual case.
