I've read through almost all the past post about cutting my front cylinder holes and didnt see anyone mention it. So Can I use cutting oil when cutting my front cylinder holes? Because I seem to be going through alot of hole saw bits. if not are there any special brand of hole saw that I conld use? Thanks guys. and if it helps its a 94 lincoln TC and I'm using Maco hole saws, yes that means I have to wait almost a week in between to get new ones off the truck that comes by work.
