3/16-Inch Cobalt Steel M35 Jobber Length Twist Drill Bits for Hard Metal, Stainless Steel, Pack of 12

Great bits. Strong and sharp, reasonable deal. Learning how to drill different metals is just as important as buying good drill bits. These are good bits if they are used properly. Educate yourself on technique and these bits will last a long time.

Good quality bits. Used on mild steel and aluminum. Very sharp and worked well on higher speeds.

I break 1/4 drill bits all the time when drilling steel (auto fabrication). this is an inexpensive approach to ensure I have a bit at the ready when I break one in the middle of my project. Great product at a great price

look fine have not used one yet

Great value and quality item

Used in hobby shop as the pilot for a threading tap. Size appears to be just fine and drills as expected.

Having gone through many cheap Chinese made drill bits I wasn't expecting much. I had to re-deck my car hauler trailer which would require drilling 100 or so holes in 1/8" and 3/16" steel. So I bought a 12 pack thinking I might get 10 holes per bit, I have used the cheaper Harbor Freight bits and am lucky to get 4 or 5 holes from those bits. After 80 holes on my first of these bits it was still going strong and I was impressed. I finally started not letting the bit cool between holes and running it fast instead of slow with pressure and finally broke a bit at the 85th or 6th hole. These bits are like the old American or German bits, made to last. I highly recommend these.

Would purchase again
