1/16 Inch Cobalt Drill Bit Set - 5pcs M35 Metal Bits With Split Point Tip for Steel, Hard Metal, Cast Iron (1/16" x 1-3/4")

Great tool

Nice sharp bit has held up good at this point at a good value.

I built a no weld go-kart out of steel. As you can imagine I had to build brackets for everything so that everything could be bolted together. For the bolt holes, the thickest steel I drilled through was cold rolled quarter inch steel. These bad boys pierce right through on medium drill settings. You definitely need a sturdy, variable speed, reliable drill and of course a good punch to start your holes. Unfortunately, I cannot say how accurate the starter tip is, as even with using a punch to plot and start the holes, the bit/hole "walked" a bit at the end of the day. Note that I was drilling this freehand without a drill press though.. I'm sure a drill press would have made things a lot better. Out of 5 bits in the pack, I drilled hundreds of holes and still have one bit left over. I would definitely recommend these.

nice drills will buy again

works as said, very good purchase quality good, will see about durability.
