Fast acting jam free cutting drill bit.
This Black oxide step drill makes excellent holes 2 times faster into aluminum, duct, steel and sheet metal rather quickly. I was able to make a one inch hole into this sheet metal panel to run electrical conduit. What a breeze with this drill bit.

A fast way to drill large holes in a variety of materials from soft to hard metals and even plastics that would shatter with standard drills. Pilot holes are not necessary as these bits self start quickly and once you get going they cut fast and you will get to your desired hole size quickly so marking the stop point on the bit is a good idea so you don't go too far. I was pleased with the minimal amount of burring on the back side of the hole even on thin sheet stainless steel. A fast pass with a sanding disk and it was gone leaving a clean round hole.
I have a few stainless brew pots I wanted to put valves in and wanted to test the bit out before the real deal and everything went great. I grabbed a strip of scrap the same thickness as the pot I wanted to put a valve in and the hole was clean and I was able to get up to the correct size quickly without distorting the metal. Now I just hope my stainless welding skills are still up to the task.

I was pleased with the speed of cutting in 1/8 inch mild steel bar stock to make some brackets. I found with a bit of cutting fluid the bit stayed cool and breezed through the material.

Well made with two different sets of steps built into one drill bit.
The first set of steps goes up to 7/8" and the second set goes up to 1 1/8".
The bit has dual cutting edges with a spiral pattern and the packaging says will will work with hard metal. Milwaukee also says it will start twice as easily in stainless steel and last up to 15 times longer in stainless.
On 1/8" galvanized steel I found it cut well.

Makes holes quickly and smoothly by employing smaller steps and a second flute to clear debris and dissipate heat efficiently. Be aware however, that these things result in a longer tool that requires more clearance behind the surface you are drilling into so LOOK before you leap to avoid unpleasant (or costly) surprises. Bit is made with a very hard (read durable) material which results in a significantly longer tool life. All of these features drive up the cost and are most important to tradesmen and not the occasional DIY'er when justifying the expense.

Great little bit. I use this on my PVC project boxes and there is a little trial and error so this step drill bit makes finding the right hole size a complete breeze. I simply start small and if that doesn't work, I go to the next size and so on. There is plenty of thickness too so you don't have to worry too much about the next size hole starting to cut in before you actually want the next hole size drilled. Its simple and does exactly what I want it to do.

I owned other brand step bits over the years and find that the starting steps dull well before the final largest step. That or they have poor starter pilot points and require a separate pilot bit to hit the precise location to start.
The Milwaukee Cobalt step bit starts out with a precise pilot hole and follows through with smooth cuts at each step. I use steps bit for electrical runs in 1/2", 3/4" and 1" conduit. This Milwaukee bit gets all my holes punched with just this one bit.
I haven't used it on stainless but so far the Milwaukee has handled common metal of electrical pull boxes; both painted and galvanized.
It cuts through thin sheetmetal covers like its butter. On 18 gauge and thicker material I slow the drill speed down just to keep the bit from heating up, but it takes on the task without any bucking.

I've had great experience with Milwaukee products & this step drill has easily met expectations. I've had to drill holes in many different types of materials in the last couple of years & this particular drill bit has made this task much easier. I only wish I had discovered it before I had to make up a bunch of hold downs for a shed I built when I retired. It would have make things so much easier.
