Take a quart of the Rigif Dark and pour a little can of Tap Magic into it.

you can just threaten the barrel with the tool and shavings will fly off.

I flush Mobilmet 766 with 1qt ATF per gallon of 766. Chambers come out smooth, sharp and shiny. Threads: Vipers venom, rigid, tap magic steel, emuge, 766 all will work fine.

I tend to stay away from tap magic because of the paint peeling and corrosive attributes- and its local to me so that hurts even more.

I been hearing about Habcool 318. Anyone ever use this stuff?

 

[GenePoole]

Since being introduced to water based coolant and a through-the-barrel system, I've never used stinky oils except for threading.

 

[HillbillyLongRifle]

I just dont see the use for a flush system with what i do.

 

[HillbillyLongRifle]

Im not knocking flush systems i just dont need it for drilling and boring a chamber and then finish ream.

What you are using will work perfectly fine. If you are looking to improve upon your chambers, think hard about flushing cutting fluid through the muzzle. I drill, bore and ream as well. Just curious, what are you seeing that you seek improvement on? In my experience, I see quite a bit of improvement in neck area finish.

Sunnen MB40 honing oil. Animal fat, Sulfur, and Chlorine. Great finish on chambers and great for threading.

Don't know about JGS, but both Manson and PTG recommend dark sulfur cutting oil and not synthetics for HSS reamers at the speeds/feeds we operate em.

I do use Vipers for brush on, seems to have a little more lubricity to me. But Ridgid works just fine in my flush system at half the cost...

I have used Rigid Dark, Rigid nu-clear, Sulflo. and some others. I suspect used motor oil would work fine but haven't tried it. WH

I use a reamer pusher, holding the reamer in a t handle. I can not feel the reamer cutting with the X-tra thick, I feel resistance...never seen anything like it. Stays on a part at 300 RPM. With some fluids, you can feel what seems like the grain of the steel when the reamer is cutting, but never with the X-tra thick.

I have not seen any other product reduce friction on a reamer like the Tap Magic X-tra Thick. If you pre bore a chamber, fill the chamber full of the fluid, then load the reamer. As you start running the reamer in, you will wonder if the reamer is even cutting....then you see the chips!

I started using Tap Magic extra thick about 6 months ago,not for chambering but tough threading, and milling jobs. It's been impressive. Oh,and have moly D on hand too.

Cool, thanks for the info.
I see it online for under $120 for a 5 gal- that's way less than Ridgid.

Admittedly, much of the chemistry of all the neat cutting oils is way beyond my pay grade- and confusing.
Chorinated additives, sulfur content, etc. Some have both, some one or the other- or none.

Is the viscosity similar to darker cutting oils?
Do you use it strictly for chambering, or all ops where lubrication is beneficial?
