What is a good cutting oil

[JamesLoren]

Hi, what would be a good cutting oil for using on cutting steel?I am going to recrown a barrel, using a hand turned 12 flute cutter, The directions call for using a good oil, what do think would work the best? I am looking for some thing that i can find at a local hardware store, or lowes ?Thanks.

Brownell's Do-Drill is the best....by far

But the tap/dye cutting oil that you can get at sears, Ace or northern tool works great too. CLICK HERE

Tap Magic works for me. Most any industrial tooling provider sells it.

Tap Magic here too, note that they make it in various formulas.

I generally have a multi purpose can and an aluminum can.

JamesLoren, What is the best? Well there are many that will get the job done as mentioned above. As a gunsmith, I use 6 different cutting oils depending on the job at hand. Do-Drill, Relton A-9 (aluminum), Tap Magic Extra Thick, Cool Tool, Hercules Dark Cutting Oil and Ridgid Dark Thread Cutting Oil. For cutting a crown, I use either the Hercules or the Ridgid. They keep down chattering marks even using hand tools!.................Dick :wink:

I've had great results with Do-Drill but I'm sure the others are good...

Jergens lotion if you don't have anything else.. It's really not too bad..

I use plumber's lard oil for all my cutting and machining tasks.
