YougfinCobalt Drill Bit Set for Hardened Steel- 29 Pcs M35 Metal Drill Bits 1/16 inch-1/2 inch, Twist Jobber Drill Bit for Stainless Steel, Cast Iron and Wood Plastic with Indexed Storage Case

I do a lot of construction work at our house on Montenegro and since the price of steel there is literally <20% of Home Depot or Lowes price, I use a lot of it. If you have to do a lot of drilling into steel, these cobalt bits are essential. Much less effort and they stay sharp longer. I take a box every time I go and give them as presents. They are much appreciated because although the steel is inexpensive, tools and consumables cost more.I particularly like this YOUGFIN brand because the bits come in a really good case. (Cheaper cases break easily in a tool box.)

Great value, works great!

They worked out just fine from my projects, metal or wood

High quality; excellent choice of size; handy storage. Hubby likes it very much.

Great

Very good drill bits

THESE ARE GARBAGE. I'M TELLING YOU THESE ARE GARBAGE!!!! First bit I tried in steal melted the tip. Next bit I tried broke. I had my neighbor who's a mechanic try one and he said they are junk. They certainly are not worth your hard earned money! If you do buy them, look at the tips. They're not even uniform shape and sharpness. YOU'VE BEEN WARNED!!!!!!!

Used this set multiple times for a variety of projects. The drill bits are useful and sharp and the hard shell case is a nice bonus. Only needed these for wood applications, untested on other materials except some vinyl siding. Cuts quickly and cleanly. Seems to be a high quality set! I would buy again. Updated review: bits drill through hard metals without any issues. Also, none have broken or worn out with repeated use. Really just as good, probably better, than other higher priced brands I've purchased!
