Metal Drill Bit Set, Yougfin 29PCS High Speed Steel Drill Bits with Black and Gold Finish 1/16"-1/2" M2 Drill Bits with Index Case for Wood, Plastic, Low Alloy Steel and Metal

Bits are good quality. I've used several and they work really well. Bits come in a really nice index case.

Excellent tool with box

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!

Size for the variety its nice and sharp. Great value for the money. Works well. However, the case began to break apart. The only downside of the kit. Cut speed is nice.

Great drill bits and drill stainless steel very well without burning up the tips highly recommended cutting ability is great

junk. cheap made. they break in half. couldn't even do the easiest task.

Durability.

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.)
