TRIM Cutting & Grinding Fluids SC520/1 General Purpose Semisynthetic Fluid Concentrate, 1 gal Jug

Mixed 60 mL to 32 oz water. Working well on mild steel,aluminum and cast iron. Corrosion inhibitor works very well with no sticky residue on parts

Wide range of effective concentration. Stays emulsified well with intermittent use a few weeks in between. Has almost no smell and hasn’t cause any skin issues. Protects the metal well, the mild steel filings I left on my bandsaw have little to no rust which was surprising to me.

Been using it for a while machine is not rusting

5 star product and seller.

I have used this in Milltronics VMC for about 8 months with no bubbler and it still has the same mild scent, almost unnoticeable. Corrosion prevention appears good. It will irritate your skin wear gloves when handling for very long.

I use this in my band saw. Great product. Flows as it should, almost films, and has excellent corrosion inhibitors. Also does an excellent job clearing the shavings away from the cut. I do run it a little thicker than they recommend since I dont have a high volume shop waste is not an issue. Highly recommend this.

Great Product, Fast Shipping! Just as good as HyCut at 75% less cost!!!!

I read through some of the comments on the mix ratio and settled on trying 5 oz per gallon. Ran my mill in the evening and shut down. In the morning I came into shop and the mill had started to rust. I cleaned that up and increased my concentration to about 1/3 of a gallon of Trim to 4 gallons of water. That works pretty good but I still see a little bit of tendency to rust here and there. Thus I am going to use a full half gallon of Trim to 4 gallons of water. That might be a bit heavy, but rust is no fun! I spent about 20 years in the machine shop in one career. that ended in 1994. So I have seen my fair share of coolant. I would say Trim does a nice job and is pleasant to work with vs what we used back in the day. But do watch your concentration level! P

Works very well at a cheap price Not intended for mister system

Its hard to figure out mix ratio, but with enough reserch most places say 3 to 6%.. But to eliminate machine rust I go closer to10%
