PC-10 is a cutting fluid that is unsurpassed by any available today. Robart Manufacturing was able to improve their tap-life substantially. Before
PC-10 they were getting 1000 parts per tap. After PC-10 was added at 30% the performance increased to an unbelievable 8000 parts per tap!!! Especially effective with stainless.
Penn United (makers of parts for the Robo-Grip pliers) was able to
double their production speeds! Conrail uses it as an axel press-on lubricant. Can be used straight or as an additive to your existing cutting oil at 10-30% addition by volume. Presents no unusual disposal problems. The list of testimonials for this
particular product is long indeed. Request them! By the 55 gallon barrel, PC-10 is about $35.00 per gallon.
