Cone Drill Bit Set
Not for stainless steel!
Nice looking set of cone cutters (in cheap plastic box - not wooden anymore) however they didn't want to cut stainless steel. Not sure how the previous reviewer managed too... I wanted to enlarge a kitchen sink hole from 28mm to 30mm but the cutter managed about 1mm before loosing its edge and then just getting hot. I ended up enlarging the hole with a cheap hand file which was surprisingly easy. I imagine they are fine for other materials just not 316 stainless steel!

Perfect for a few quick holes
This performed perfectly. Given the price I was not expecting much so purchased 2 sets as I needed to bore holes through 2mm stainless sheet. My purchase was over zealous as the first set went through no issues and didnt need to touch the 2nd set. Now stored for use another time as they were more then man enough for the job.

Budget Cone Drills
Drilled into 1mm mild steel easily, though the shaft did spin in the drills keyless chuck a little.
I will only need to use these occassionally so for me the quality and price are good.
