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

This question is from Step Drill Bit Kit (10-Piece)
Asked by
Seattle
Read all my Q&A
April 17, 2014
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.

Answer: 
You can cut in high speed through plastic. You might see some plastic sticking to the bit or melt but the Black Oxide coating will help with lubricity and will help keep the heat down.
When drilling in aluminum, Speed #1 on a FUEL drill will be fine, even high speed with an acceptable thin gauge. Be sure to check that no material is left in the flute or stuck to the cutting edge after each cut.

Rated 4.4 out of 5 by 27 reviewers.
Rated 5.0 out of 5.0 by The kit is a good value I was going to get the step bit by itself and saw the kit. You get the great bit, and some extra drill bits and a case for less than if you purchased the two themselves. The regular drill bits are nothing to get excited about but the step bits are really nice. July 5, 2016
Rated 5.0 out of 5.0 by Excellent. Really Great purchase This drill bit kit is light weight and easy to use. Convenient. October 18, 2016
Rated 5.0 out of 5.0 by Right product Very good product was easy to breeze to my project with no problems. August 29, 2016
Rated 4.0 out of 5.0 by Bits and step drill I haven't used these yet but I like the brand and the appearance . August 26, 2016
Rated 5.0 out of 5.0 by Excellent product These are pricey, but did the job nicely. I am sure I will need them again with the various projects I am working on. April 7, 2016
Rated 1.0 out of 5.0 by Not Good for SS Good for everything but stainless steel (SS), the bit overheats and is useless afterwards February 6, 2016
Rated 1.0 out of 5.0 by Waste of Money!! Okay Hombrewers, I know many of you are like me and looking for a step bit to punch holes in your kettles. If you have a reconditioned keg these bits MIGHT work for you. I am using them on Stainless Steel Kettles 3mm thick and these bits are failing miserably! I have a hole in my kettle but the bit did not finish the cut, heated up and became damaged(and yes it was on a cordless drill with oil). So like an idiot, I went and bought a second set of the same bit to see if maybe I just had a bad set...NOPE same thing happened before I was finished with my second hole again!!! Well since my pot was ruined I tried a third hole and forth hole, all at different speeds, all at different pressures, and all failed to cut resulting in damage to the Drill Bit. $100 worth of damaged Bits later I am writing this review and saying good-by to Milwaukee bits... Since this product has received so many 5 Stars I will be monitoring to ensure the reviews aren't being filtered. If they are, look to Facebook for a update because that is where ill go to post it.

Rated 5.0 out of 5.0 by Best drill bit set around! Bought this step up set and couldn't be happier. The bits drill thru 3/8 Steel like a hot knife thru butter but faster! The step up bit is hands down the best on market and makes short work of enlarging holes. Don't go cheap on your bits, also make sure to use oil when drilling thicker Steel as it will keep the bit cool and extend the life of it. December 29, 2015
