I use it for lathe cutters and occasionally tweak the edge of a mill, but I
would not trust myself to completely resharpen a mill retaining the shape.
But this thing is useful for other tasks too: I had to cut holes in a bunch
of floor tile. Ever notice that things like RotoZip bits that say they are
good for cutting tile also say in the fine print wall tile only? The floor
tiles I had were dulling carbide cutters very quickly, then the dull cutter
would crack the tile. That is actually when I bought this grinder:
Resharpening the bits frequently got the holes cut, and I think I saved half
the cost of the grinder on that job alone.

Here is one quote from it: That isn't really a "tool and cutter
grinder". A real tool and cutter grinder is a very different
machine. That thing is mainly useful for touching up lathe bits and
other single point tools. It is not suitable for sharpening end
mills, dovetail cutters, Tee slot cutters, etc.

I couldn't sharpen an end mill or a dovetail cutter with a $10,000 CNC
grinder. I have hard enough time with my drill doctor. :-) I send
all that stuff out. All I want to do is grind single point turning bits.

I bought the one sold by J&L Industrial a couple of years ago (their
price was $159). It is basically a Chinese copy of the Baldor, at
about 1/5th the price. It accepts the same plate wheels as the
Baldor.

I sometimes wonder if there is just one set of patterns for each machine
in China and all the foundries share them to make molds. Yours is
probably very close to the HF. How is it working?
