Maybe simple question... cutting oil?

[Lyaec350]

When applying cutting oil to an object being drilled in a drill press, (or tapping oil for tapping), how and where do you apply it? The oil I got from fleet farm is specifically labeled for cutting/drilling and tapping, but it comes in a mini jug kind of like engine oil rather than the familiar spray can with little red tube. How do you apply this type of oil? Brush? How much do you apply?

[Muttly]

oil can?

I use a flux brush or oil can. You can't use too much oil, the more the better. It keeps the drill/tap cooler as it lubricates. The thinner lube evaporates cooling the metal and lubricates.

[mulepackin]

I use a finger trigger oil can. Start with a few drops and add a little as I go, you will kind of get a feel for when the cut starts to dry out, sound changes, cutting curls change, etc. I agree, you can't use too much.

[brianpgriset]

Get yourself a nice Eagle Manufacturing pistol grip oil can. BEST pistol grip oiler ever made! You'll have to get them on ebay though.

I've been using the same set of quality drill bits on my press for over 8 years and every one of them is a s sharp as when they were new. All I do is spray WD40 when I am drilling into steel, keeping it wet. And also, it helps to know the proper drill speed for different metals, and thickness. Pick up a machinist bible and it will tell you all of that valuble information. Most people set the drill up to the fastest speed and just dig in, but it does make a difference to drill different materials at different speeds.

The primary function of cutting fluids is heat removal. Lubrication is a secondary function. Ideally you'd flood the cut area.
Cheap plastic Ketchup squirters work well.

[Yotaforce]

Kind of like when I was sharpening bed knives on an automated grinder, I would use anti-freeze in the machine to keep the blades cool.

[OldCarGuy]

Franz is right on. The function of cutting fluids is heat removal and not lubricating. When drilling steel water mixed with an antirust inhibitor works best. As oil will smoke too much from the heat build up, particularly drilling larger holes. And any old plastic bottle with a smaller hole in the cap will work fine.

[Elroy]

You make a good point about the heat removal but there are a few things missing from water. All cutting fluid worth anything have a high pressure lubricant to prevent galling. Elroy prefers tap magic especially on stainless. Use water on stainless as a cutting fluid and your going to have nothing but problems.

Now grinding would be a different deal. Still there are better things than water. You know it and so does Elroy.

Well, if we're going with personal preferences, LARD is still about the best for threading pipe and cast iron. Of course the job tends to start smellin like a bacon sanwich, and you do get hungry, but it cuts real nice.

If you have a lot of pipe to cut, throw some sulphur in with the lard. Don't smell near as good but it cuts damn well.

Turpentine is real good on aluminum and ss as well, because it cools as it evaporates off.

The best was CoolTool when it was a combination of Sperm Oil and Trichlor, but the government went and screwed that all up with the EPA regulations. Sperm Oil is the ONLY oil that flows toward heat rather than away from heat.

[russlaferrera]

Franz, I was in agreement until we reached Sperm oil and Trichlor. Never heard of it...to embarrassed to ask where Sperm oil comes from.

[mulepackin]

Franz, Do you know what the action is of the sulfur? I"ve always used a thread cutting oil for steel pipe that has sulfur in it, its almost like sulfurated molasses. It cuts great, and almost seems to change the nature of the steel at the level of the cutting teeth on a threading die, but certainly works better than an oil alone.

[Franz©]

Sulfur is a lubricant under high pressure, just watch older Diesel engines self destructing their injectors and injector pumps as they switch to Ultra Low Sulfur fuel.

Sperm oil comes from nasty men who murder Sperm Whales, the largest creatures on Earth, chop them up and render the blubber into oils. It has some very unique propertys that to my knowledge have not been duplicated in any other product. Now put the Playboy down and resume working in the garage!

[Elroy]

Elroy just read that some where. Who said that???

[Elroy]

a lubricant under high pressure

Do you think that has any thing to do with "cold roll" being avaiable with high lead content??

[Franz©]

Leadloy has been common for years, cheap alloy good enough for some aplications.

The fun part will be when the child safety croud finds out and insists on lead being removed from steel, and all lead containing steel being replaced. The Congress is already stupid enough to go along with the program.

Dammit Franz! You know some dumbass will read this and say "well someone said it was possible to replace all leadloy in use" to their Congressmen and you know what will happen? More CONgress rather than progress.

[Franz©]

Brian, you're a young man, so allow an old fart to enlighten you.

Back in the time of World War I a group of reporters cornered a high ranking government official and demanded he give them a solution to the horrible German submarine problem.

After making the appropriate gestures that indicated he took the problem seriously, and staring into space for an appropriate amount of time for a man of his stature the Government official said "Boil the oceans.".

The reporters were suitably impressed with the answer, and wondered why they hadn't thought of it themselves, and after making notes, one asked a follow on question. How do we boil the oceans. The Government official responded "I have no idea, I only make policy.".

I only make policy young fellow.
Now if you're smart, you'll designate yourself an expert on removing lead from leadloy, and after creating completely meaningless phoney credentials market your services as a consultant and expert witness. Feel free to send me a paultry 5% of the income stream as an honorarium.

Before the ban on lead, I used a mixture of bacon grease and white lead for threading pipes and tapping threads in steel. How does that stand up to sulfur and lard?

Noting has replaced the old sperm oil though...

[Franz©]

OCG, I still recall damn near getting fired in 1963 from a job I was probably trying to get fired from for running a hole saw thru cast iron a few thousand times with lard.

Bacon grease & sulphur would probably stand shouldre to shoulder with bacon grease & white or red lead as a cutting lube, but the sulphur would stink worse, and you'd probably still get hungry for a bacon sammich. Then again, when t turned rancid it would get pretty bad either way. It sure wouldn't cause Dain Bramage like all that white lead we ate did though.

[rock_climber]

After being in a shop for 27 years this is the best product I have found when drilling for coolant. The coolant is Castrol Syntilo 9918.

I would hate to think how much leadloy we use each week. From 150 to 250mm dia. That and cast iron. The sad part it is all machined away for the final product, which ends up 416 or 420 stainless, cero, nickel and diamonds.

Machinest friend of mine uses canned WD-40 and transmission fluid mixed 50-50. Uses a common spray bottle. I've tried it and it really works.

DAMMIT ELROY!!! IF YOU KEEP ON SPEAKING IN THE THIRD PERSON........i AM GONNA SEND YOU A BILL FOR MY TIME. THE TIME I SPEND CLEANING MY KEYBOARD AND SCREEN OFF FROM SPITTING MY COFFEE ALL OVER IT!!!:spit:

Don't do it!
He'll probably pay by a check written in the third person that will disolve when you spit coffee on the check.

Franz thinks Elroy has just written too damn many government reports and has fallen into the habit of replacing self referencing personal pronouns entirely.

Oh? And when did you get a BIOLIGY degree, too? I think you better get your sorry ass into reading something besides WELDING books! The sperm whale happens to top out at about 70 feet in length, while the blue whale goes to 110', both having essentially the same structural shape and density. In NO WAY is a sperm whale the largest animal on earth. That is pure, adulterated BS! (OK, folks. I did my best to imitate Franz' rip-butt reply to some poor SOB w/ whom he disagrees. How did I do? OK, for a beginner?) :) :)

Aw JK, ya almost made me cry. I do that sometimes when I get to laughing real hard.

I might be upset by a young upstart like yourself if I didn't realize immitation is the sincerest form of flattery. You got some work to do son, but if you study hard you'll get there in a few decades.

Hell, I don't need a biology degree, although I did once pursue a University course on the interrealtionship of sex and religeon for a while.
Now I suggest you revisit that sourse of information you used and recheck. See, the Sperm whale used to be the largest mammal on the planet, but because all those mean men chased hell out of them trying to harpoon Sperm Whales they had to slim down and get faster. That left the less tasty Blue whale the necessary time to evolve into a longer whale since it wasn't hunted. If youjust would have asked I woulda told you.

[jklingel]

"If youjust would have asked I woulda told you." Dang. Next time I'll ask. I should have known you weren't wrong after all. Sounds like you and I have something in common. Made a mistake once; thought we were wrong, but were really right. Glad you saw the humor in it, but take the hint, please. "Young upstart"? Well, how flattering. Maybe I'll dye my beard and hair and start all over. "In a few decades"? Hell, I'll be dead from old age by then. Weld on.

Behave yerself JK or I'll call ChromeDome Steve in Ancorage to come over and slime bomb ya with some crude from Prudo. I am not without connections or favors to call in. Rhen again you might just like Ak crude to color your beard.

[jklingel]

Hey, what is old Chrome Dome up to these days? Haven't seen him since base camp in Deadhorse; now there is one wild guy. Suzie Laderman used to really tick him off. She was a trip, too; maybe ON one; dunno. Never could figger EITHER of 'em out. j
