I agree with the QCTP thought, couple of reasons, ?FIRST, for me it ?was setting tool bit height! I¡¯m NOT a machinist, bought a 7X five years ago and the first ¡°upgrade¡± was the Quick Change Tool Post. ?Over the years I¡¯ve picked up a couple more tool holders, makes setting the height and tool changes a POC (piece of cake)

I went the ¡°Cheep¡± HF ?¡¯ tool route.¡­ mistake¡­¡­. Then I bought a ¡°pre-ground¡± set from Grizzly¡­¡­.. beautiful (expensive) wood case, real cutters! Of course I ?jammed em¡¯, dropped em¡¯, galled¡­. used and abused em¡¯, ?they got dull! What to do now, learn to grind my own. As a concept, up there with sliced bread. One can become? adequate with a cheap 6¡±grinder, and a ?little practice! ?LMS has (2) two items that were invaluable to me during my ¡°steep¡± learn curve. ?This video¡­ ? and these HSS blanks¡­.

I second the QCTP setup....? I got one last year and I honestly don't know what I'd be doing without it right now....

Jeremy,

Do yourself a huge favor and get a QCTP setup from LMS. See: for their selection; I don¡¯t know which one you need right offhand, but they¡¯re very helpful if you ask. While you¡¯re at it, buy a few HSS toolbits and grind them according to your needs.

When I purchased my lathe, I also purchased a few sets of cutting tools:





The first ones, the carbide, are completely junk. None of the angles are correct. It is almost like the carbide was brazed on upside down.

I have had decent luck with the HSS cutters in the second set. However, they are so small 1/8", you have to use the holders. The holders cause the cutter tip to be a significant distance from the tool post decreasing rigidity.

Does anyone else use the tinny cutters and if so what holders do you use?

Thanks,

Jeremy
