You can also get HSS inserts for indexable lathe tools. I have some DCFT (I think) for a particular boring job I occasionally do, think they are Arno the ones I have.
Aye and now I have just annoyed myself by mentioning them. Looked for them to see if there was any info on the make and I can't find them Found the bag they were in but they are not there, must have fallen out through time and probably threw them out when I was sweeping up, once a decade occurrence
