cutting oil

[JPB3]

I need to resupply my cutting oil... This would be for use on chambering reamers... What are you guys using now..

TIA

I just use whatever cutting oil is available.

The machine shop at work uses a cutting fluid from Castrol for heavier duty cutting. Kinda thick & gray in color. Can't remember the name of it. Mostly use it for cutting threads with some of our larger taps, or if the material is really hard.

Viper works for me...

 

[tobnpr]

Ridgid or Oatey dark, just standard stuff. Cut with 20% ATF for a flush system.

Viper is very good.

This! Just hit the hardware store..... Ridgid or Oatey.....probably made by the same people......works just fine

Ridgid dark oil mixed with 15% moly d. Great for hss tools.... threading and chambering..

Flood coolant for everything except threading. I use Viper's Venom for that.

I tried all of the oils and ended up with the best one being plain old Rapid Tap.

Rapid Tap, 1 Gallon - Grizzly Industrial, Inc.

<li>Fine machined finish even on tough materials such as aluminum, beryllium, brass, bronze, cast iron, copper, iconel, magnesium, molydenum, stainless steel, and stellite</li><li> No 1,1,1 Trichloroethane - ozone friendly, non-toxic, and non-flammable; non-WHMIS</li>

For threading I use the clear Rapid Tap.

I am a hobbyist. My reamers are precious. I do not use a coolant though system. Tap Magic Xtra thick is what I use with it's viscosity of 300, it will stay on a part at 300 rpm if you are turning it.

Also, if you are using a reamer pusher, you will not feel the reamer cutting the steel, all you feel is resistance on the reamer pusher as you hold it. I warm the X tra thick in a baby bottle warmer that sits on the headstock of my lathe. You will never see chip weldment on the reamer flutes when using the Tap Magic Xtra thick.

I feel like this product is the very best at reducing the friction between the reamer and steel it is cutting, and there is no other product that will compare that I have used...none.

I use Castrol Moly D to thread with, and when it is gone, I will use the Xtra thick to thread with. I never quit trying different products.

All through the mid 80's, we used High sulphur products/mixed with Transmission fluid to a great degree of success. The Tap Magic Xtra thick is in a class by it's self when it comes to reducing friction between the Reamer and chamber, something you just have to feel as you hold a reamer pusher...incredible to say the least! I get my Xtra thick from Zoro when they have a sale with free shipping and 20-25% off.

If you are cheap, then just keep using Oatley. Vipers Venom is sure an upgrade from Oatley!

I like the Xtra thick for threads. I got chatter with it reaming.

I don't want any moly products or extra slick stuff, cutting not trying to reduce friction. I tried a bottle of engine assembly lube and you almost cant cut with it. I still use this on my reamer pilots though.
I use and am about out of a one gallon can of extra dark honing oil. Not sure what is going to replace it but sounds like the tap magic dark might be in order.

I have NEVER got chatter from Tap Magic Xtra thick, you have another problem, not related to lube.

It was ok. Too thick I think, for reaming.

Great for threading.

That tap magic take the paint off your machines and rust the ways?

 

[JPB3]

Dusty, what do you use?

 

[LVLAaron]

Tap Magic, in my opinion sucks, unless I'm tapping a hole. Its hard on the skin and stains metal.

Castrol ilocut 486.i use it with a flushing system.pumps easily,great lubrication for reamers and leaves excellent finish on chambers..no problems with it at all.highly recomend it.

 

[AckleymanII]

Tap Magic makes a LOT of different cutting fluids.

The Xtra Thick, is actually that. I put the fluid in a squirt bottle on top of the headstock in a baby bottle warmer, then the viscosity is MUCH thinner, but you still maintain the cutting properties. The first time I used the Xtra thick, I had the shock of my life. I was starting to ream the chamber after boring, the reamer was going in, but I could not "feel" the cut between the reamer and the barrel steel. I went in half an inch, still could not feel any friction between the cutting tool and the barrel....I had never felt a lube reduce the friction in the cut like this before, and I will try about any lube to save my tooling, get a better cut, and especially stop chip weldment on the reamer flutes. I am still learning, and I hope I never quit.

I use a reamer pusher, where I can feel the resistance in the cut, and feel the cut as it happens on pre bored chambers.

Dusty, what do you use?
