I need to ream some 1/2" and 3/8" holes in some 12L14 and was wondering if 1/64" undersize is the correct size for reaming? I haven't done a lot of reaming so I'm deficient in reaming knowledge.
Thanks,
Ed

Hi
Ed
That should be fine
I use 0.2 mm undersize
Never turn the reamer in the wrong direction (but you will already know that)

Thanks John. I'll soon see how it goes.
Oh, what RPMs should I be using for 1/2" and 3/8" reamers?
