I'm working on my first linerlock and this morning was trying to countersink the .055" Ti liners using a Toolmex #0 HSS 82° Zero Flute countersink.
I tried running it at 1180 rpm with cutting oil and almost completely countersunk one hole before burning up the bit. It was a double ended countersink, so I flipped it over changed to 670 rpm and tried to complete the hole I had started. I could see it start to smoke, so I stopped before completely burning up the bit this time, it did not appear to be cutting at all.
I either have the wrong tool or am using the wrong feed & speed or both. Any help or advise would be greatly appreciate.
Thanks
