Milwaukee Electric Tool 48-89-9201 Step Drill Bit, No 1

I use this to enlarge bolt holes in angle iron and definitely are sharp. Better than using a 1/2" bit. I have purchased a second because I hit tool steel with the first one and it slightly dulled it.

Had to make a dozen or so 5/16 " holes in 1/8 flat bar. I won't say it was like a hot knife through butter, but with some patience and oil lubrication, it worked. Once the tip pokes through, the step portion of the bit is much faster. I initially tried making the holes with a regular bit, after much trying, I never did make it all the way through the bar. Definitely a keeper.

Amazon sent the wrong size but these are awesome for starting holes and great if your using 3/8 allthread etc. We drilled many holes with no issues so far.

Why didn't I know about these bits? These are so easy to use and they are so fast to drill with.

This bit is a sharks tooth. Super sharp and durable. It will get the job done

Works great

I do collision repair and use this product daily. I have had several and will never be without one.

Unacceptable
