I have some milling cutters that I think are called end mills or maybe end/slotting mills.
They are flat on the end with one cutting edge passing across the mid point with sharp sides like a twist drill.
I need to mill a 12mm wide slot in a chunk of mild steel (on my lathe of course) 90mm long and 20mm thick.
I've drilled a series of 12mm holes along the centre line but really do not want to file out the remainder (too lazy)
The chunk can be mounted firmly for cutting but I think I have read somewhere that using these cutters to cut both sides of a slot at the same time is bad practice.
It would have to be done in multiple passes till half way through then flipped to finish for full depth.
My question is:- can they be used this way?
