Question about Cool Tool II and chambering

I just bought a jug of Cool Tool II and am getting ready to ream a couple of chambers. I've always used a good sulfur cutting oil but it is getting harder to buy locally.

On the container it states to use full strength or blend with a good oil. Have you tried it both ways. What are some of your findings about this product and barrel chambering compared to cutting oil?

Thanks for any advise.
 
I use Cool II for the last 15 years and don't know of anything better. Just buy it from MSC they have it in the 5 gallon drums. I use it straight in a squirt bottle. Never cut with anything. Use reamer and drill bits at the one and a half rule as in all reaming and drilling operations.
