Hougen 11742 RotaMagic Metal Cutting Oil 10:1 mix Super Concentrated Cutting Fluid 1 Gallon

If you never used this, you should try it. I found it to work very well when using annular cutters. I was a bit apprehensive given the cost per jug. However I drilled tons of holes and the cutters are still cutting like the first cut. The product does leave a slight residue but it isn't a big deal. I rather it than oil. It works well with spiral bits too.

I started a new job a few months ago ( retired once and then got bored, lol). At the new job I noticed they didn't use any kind of lubricant when drilling holes into carbon steel with regular twist drill bits or "Hougen slugger bits". I asked why they didn't use a lubricant and the guys there said because it leaves an oily residue. They were flying through annular bits like crazy. Maybe boring half a dozen holes before they trashed them. I have a machining background so I knew this was crazy. So I bought this to show the guys at work how things should properly be done. This work great. Now the company will start stocking this.

Excellent product in the side of steel cutting

Hated to spend the cash for a gallon. Hated even more not using it and paying $$ for ruined cutters! This stuff works great!!!! I was foolish for not using it before. Has saved me $$$ in cutters.

My first time using this y-type of product since I just got a mag drill but seems to work very well.
