Asked by: homebrewer
I think they would do very well. I used them on an old metal box that was a harder steel and it did great.

Step Bit - Sufficient Lubricity from Oxide Coating for High Speed in Plastics too? Aluminum?

Here and on Milwaukee website I see "Metal/Plastic" and "Steel and Plastic" described. When chucked in the Fuel 2604 drill, experience tells me that High Speed (Setting #2 on Drill) is fine in Electrical Steel Enclosures / boxes, but in plastics do you recommend the slower drill speed (Speed #1) to prevent melting or does the black coating provide sufficient lubricity to safely drill at high-speed without risking plastic melting/sticking on these new Step Bits? ALSO, is the FUEL Drill 2604's Slower Speed #1 (450 rpm if I accurately recall) still too fast for even occasional hole-making in ALUMINUM Enclosures or Panels? That is, would aluminum surely gall up on the Step Bit even at those slower speeds? What about variable-Triggered Drilling around half power/speed at setting #1 (roughly 200'ish RPM)? What do you advise in this case for aluminum? I'd really appreciate your best, practical advice here rather than erring simply on a "don't do it" reply if Aluminum can be so-drilled with low to moderate 'risk' in galling these new Step Bits.
Asked by: AmericanJustin
When drilling aluminum, spray or brush a little kerosene or WD40 on the drill bit. It works to keep the aluminum chips from sticking on the flutes, a little goes a long way. Your drilled holes will be smooth. Advice from a Toolmaker.

The first set I had drilled 4 holes and on the 5th hole it stopped drilling at 3/8" even though I was using cutting oil. I returned the first set for exchange and the 2nd set did the same thing. I'll be taking it back tomorrow for a refund.

I got this set along with the number 9 step drill bit to replace an old set of step bits. These are some of the best bits I have bought. They cut fast and leave a clean hole with little to no burs. I used them to cut holes in a steel box that my old bit set couldn't cut through and these did excellent. Another great thing from Milwaukee.

I gave this 4 stars because i have had the step drill bits before and they stayed sharp after a lot of use. I did not want the drill bits and wounder if the price would have been lower without them?
