Works well as a cutting oil though like all aerosol ones it is a little thin. The issue I have with it in particular is that it does not play nicely with the slideway oil on my old lathe - it makes the carriage stick. CT-90 brand, for example, does not have this problem.

Good price and very convenient shopping experience

A Kemp Verified Purchase

I was having to drill some thick stainless plate (which will easily kill drill bits if they get too hot) and needed some cutting fluid, found this which is a good alternative. It foams slightly into a pool that stays around the area being drilled or cut, seems to work very well, we will see how long before I need to sharpen the drill bits

Cool product

Does what it says on the tin, making the tapping of holes easier by providing good lubrication and protects the Tapping Tool Cutting edges. Also found it useful when drilling out holes to a larger diameter ready for tapping. The use of a dispensing tube makes more efficient use of the cutting oil as it can be more directly targetted at the cutting areas.

Very good cutting oil. Using it for mill drill and turning.

Had to drill 30mm through a seized pinch bolt and this cutting oil kept everything cool to the touch while floating out the swarf. Thoroughly recommended especially with the tube for targeted application.

Works well
