VersaMil manufactures a flycutter arbor for it's machine tools, and with the arbor I've ALWAYS provided a Mo-Max 5/16ths lathe bit.
High Speed steel supposedly ground on all four sides to fairly accurate dimensions. These cutters up to a year ago didn't SAY where they were made,
but I always measured them and tended to have to grind one side, because they were almost always oversize by .003. I can handle doing that, grinding a .315 cutter down to .312.
But the batch I got in today, proudly labeled INDIA in bold print, are just so horrible it's unbelievable. Every one of the cutters were tapered, and they varied not
by three thousanths, but'10 thousanths of an inch. One tapered from .312 down to .300. Every one of them was a different size, most not square. Now maybe as a lathe bit
squarness and parralelism isn't THAT important. But these bits go into a broached 5/16ths hole, so they at least have to fit, and fit somewhat snugly.
So is this the norm for 2012? I realize square high speed steel bits that need to be ground by the user are probably getting to be a limited demand item, but if
Cleveland is going to put their name on them, wouldn't you think they should at least make them SORT of correctly. It certainly ruins your day, when you have
expectations of a semi quality part, and you open a box of absolute junk. If they're this sloppy with their grinding, how am I supposed to think that the STEEL is any better.
Certainly Clevleland could still make these effectively in the USA. 100's could be ground in one chucking on a variety of grinders. Certainly there's some care needed, but
making a few hundred bits in one grinding, isn't rocket science. It's one thing to ship work off shore to save labor, but why bother importing junk. The same set of tools I put the flycutter arbor in,
I provide a 2 foot long feedtable that's flat within .001 over the entire table. In excusable to have a 2 inch cutter taper by .010.
