I've finished some 80's in the past just fine, but I've got a few more to do and wanted to incorporate a cutting oil into the process to see if it makes a difference.
I'm finishing 80% AR lowers using the modulus jig with appropriate drill press and finish router with endmill.
Will the cutting oil make a difference for the milling? Seems the bit is spinning at a higher rpm that it would just fling off. I mean, it's not a CNC machine with a water jet to keep things cool and clean.
Anyways, what cutting oil if any do you recommend? More so looking for something available at the usual big box stores.
