Customer Reviews for Milwaukee 3/32 in. Cobalt Red Helix Twist Drill Bit

these Milwaukee bits are great, they seem to stay sharp and last a lot longer than the other brands

Used to drill stainless sheet metal. Fair performance, split point dulls quickly.

Excellent job Thanks

I was hoping to replace the drillbit in a counter sink, actually flips into a driver bit, but this drillbit is too long, and it does not flip and secure because of the length. No one seems to make a bit for the counter sink that flips with the driver bit. It needs to be a short drillbit.

These are good drill bits... but... I do wish they were made of harder steel... and didn't dull so quickly...

It did a great job drilling through my steel hinge!

As a technician for a restaurant franchise, I find myself needing to drill into stainless quite often. Use these Milwaukee Cobalt drill bits on a slower speed to easily get through stainless steel. They have lasted longer than any other bit that ive tried.

No what I was expecting

works great!!!...........

Would not drill a hole in steel that already had a pilot hole

3/8 Red Helix bit worked exceptionally well! I think many users that gave bad reviews did not use cutting fluid or too high of a drill speed. On my drill press with fluid for each hole, straight and clean holes were drilled through over 30 pieces of 1-1/2" x 1/4" steel flat bar with long chips and no issues. The same result through 1/4" & 3/8" thick steel angle. Very impressed with the dual cutting angles and how effective they are drilling steel.

Great low cost product for drilling through SS
