Tap Magic Aluminum on aluminum
CRC cutting fluid on ferrous ( I have a gallon). Pro Tool Lube on stainless so much for not having multiples. |

Do you have a coolant set up?
The cutting fluid\coolant works great... If not, any of the stinky cheap sulfur dark oil for ferrous brushed on... |

Moly-D works well on everything, if it is just aluminum I would use tap magic

For clean-up of TapMagic, spray down with WD-40 or Spray-on LU-711, and wipe off before it sits too long. I do that with the taps and drills also before putting away.

Quote HistoryQuoted: Moly-D works well on everything, if it is just aluminum I would use tap magic MolyDee seems to be popular. I was hoping to find something a bit easier to clean up. I've see a few folks say Mike O Cut works as well. I don't know though. |

My Dad always just used old motor oil with old transmission fluid (most likely burnt
 ) in it.Yeah it was redneck engineering but I don't remember him breaking very many drills or taps though. My first engineering job was in a pattern and mold machine shop it was a very strange mix of master pattern sculptors who could work magic with mahogany, chisels and glue all the way to new at the time Haas 5 axis CNC machines. I can't really help much with the fluid type but I remember loving the way it smelled when it was new, I can't really explain why. It was a milky light mint green and it came in Haas 6gal buckets. Many of the older mills smelled like Lysol because they kept getting bacterial slime in them, and smelled like a sewer. |

I bought some Oateys dark and clear oil to try for fun. I'm curious to see how it compares to what I'm already using. It's cheap so why not? Lol

Tap Magic Aluminum for tapping aluminum - I still have several cans I picked up years ago at machine tool shows
WD-40 or kerosene will work for aluminum Some use oil for aluminum but I did not have good luck STP Oil Treatment for steel and stainless steel Used or new motor oil for steel Castrol Moly Dee is good for steel, stainless and aluminum - it will really cling to a tap Our go to tapping fluid is Emuge Someone mentioned stinking coolant. We had a couple of old horizontal (manual) mills that we didn't run too often. They had coolant sumps in the base and would get pretty rank. We had to open the doors in the shop when we fired them up. Smell settled down after an hour or so. Speaking of horizontals. Anyone here remember straddle milling or stacking cutters on a horizontal ? With some work and a set of shims you could do some seriously cool cutting on a horizontal. I miss running our old Brown and Sharpe. I learned from some amazingly talented machinists. 35 plus years in the business. I ran a couple of Haas and Mori Seiki verticals and they would get pretty ripe. I kept Pinesol and Chlorox on hand. My machine either smelled like a pine forest or a swimming pool. Had a Castrol rep in the plant a few months ago and I mentioned adding Chlorox or Pinesol and he had never heard of it. Seemed to be shocked. Dont know about other shops but we have been doing it for at least 30 years. |

I tried Oateys dark cutting oil today for the first time. I was drilling a chunk of steel bracket for shelving. It's open on one side so it's a pain to get it really braced up right. Flex does not help with big drills.
The 31/32" drill had to be sharpened more than once through the project, which was to turn the piece of scrap into an R8 tool rack. I thought the oil did pretty well. A bit smokey. The ventilation fan I installed, the biggest bathroom fan I could find, did a pretty good job of recycling the air. I should have thought to crack the door a bit. Lol. I liked that the oil kept flowing down the bit into the cut. I apply with an acid brush out of a spill proof paint cup. Worked very well. I bought some Moly Dee but I have done any stainless jobs to need it. I've got a bunch of oils to try out.  |

I bought some surplus mystery steel at a local bolt an Amish surplus store today. They had two bottles of rapid tap and three new bottles of Anchorlube for $1 each. I couldn't pass on that. Now I've got more cutting oils to try than projects in the pipeline.

Just fyi, dark oil is usually reserved for threading. Really i just use tap magic for steel and wd-40 or kerosene for aluminum. Cast I do dry. Anchor lube is useful for something vertical because it holds there.
