Long time ago I bought a Black & Decker 1/2" drill motor, one of their promotional tools, for $19.00 dollars. The name plate stated "made in USA". This was back in 1968 and this drill looked like a pregnant 3/8" drill motor, no handle other then the pistol grip.

You could drill one 1/4" hole in a 3/8" steel plate with it then you had to put it down because it got to hot to hold. Drilling a 1/2" hole took about four hours in the same material, again because you had to let it cool off a bit before you could finish the job.

I still have the drill motor and it still works! The only part I replaced is the cord, the original is just too stiff to work with. It still runs, and still used on occasion.

In the US we just know how to make things that can last a long time, even though it was made cheaply to begin with it'll work for a long time.

yes Mert, except few things are made in USA anymore.

HF doesn't seem to have that holder in the moment.
Any feedback for that one:
?

facing as well - 16$. It will last a long time between sharpenings and
works very well. Another good way to go is to buy the 1/4 in insert
holders from HF (15$ with 20% coupin), and buy some kennametal 2151
inserts. A 5$ insert will last maybe 3 years at hobby rates of use.
They cut through hard steel like butter. The triangular inserts are
tnmp as i remember - can look up. Each inserts has three cutting
points that can be rotated as a point becomes dull. I have been using
several for 8 months for all kinds of stuff, and I have not rotated
them. I have done nasty cuts on hardened steel threads with ease.

And to follow up. I did some research since I'm now in the market for a new grinder :-)

Is Baldor the ONLY company not sourcing their grinders from China or Taiwan?

I know Craftsman, DeWalt (B&D), and the others have moved production overseas, but I was surprised that Delta, Rockwell, Porter-Cable, and especially Palmgren all seem to be using Chinese factories.

So this may be a little off topic, but I'd love to hear comments about the different grinders and people's thoughts, experiences with the different brands.

Obviously, I'd love a Baldor, but starting at over $500 retail it's kind of tough to justify spending as much on the grinder as I did on the lathe. :-) And yes, I'm checking craigslist!

Just to get a complete picture I took off the wheels and turned the grinder on with no load. Within 5 minutes, the temperature was over 200 degrees. This is where I chickened out and reached to turn it off, but I saw a wisp of smoke coming from the grinder.

This grinder cannot have more than a few hours on it at most. I only purchased it about 2 years ago and it's ground maybe a dozen lathe tools.

It was cheap so I don't mind the money so much, but the thought if this had been a motor on a band saw or other tool that is more automated, the resulting fire would be very bad.

So one more example of being careful of the ratings on the Chinese motors.

I can. Only agree with you, my grinder is bolted down on a shelf, still tries to take the shelf off the wall.

I purchased a grinder from HF a long time ago when quality was an unknown
word "there" (across the ocean). The grinder suffered similar symptoms,
using it for 5 minutes it would get too hot to touch. I stopped using it
and made a grinder from an old pump motor (C-flange) and a set of pillow
block bearings mounted on a piece of channel 6" wide X 1/4" thick. This set
up lasted me almost 22 years but finally had to retire it because the
internal wiring, not the windings, got so brittle the insulation started to
crack in several places.

I recently purchased another one from HF and I'm happy to report that I can
use it for about 30 minutes before it gets too hot. They're not too much
different from what my first one was, just a little better. Quality
grinders cost way too much for us to justify buying one.

If, as I suspect, you are using a tool which has the carbide tip
brazed on you are basically dealing with a junk tool and will not have
much luck.

if its a Chinese tool yes all that is true (I think Chinese carbide uses rat turds as the binder)
now if you use a good grade, high quality brazed carbide like micro100 ( )
you'll have much better luck
these will cut freely and last a long time even with zero top rake and even on hardened stainless
but you will have to cut the feed rate down to under .001" IPR on a light duty machine
we use these on our Swiss screw machines all the time

I had that same grinder, and it lasted me about 10 minutes. The
first second I started it up, I knew something was wrong, as the wheels
would not run true. I tried truing them up, but the motor burnt up
before I could finish. I bought another one, more expensive than the
first, and it was almost as bad.

The wheels were warped, and the bearings weren't true, and one
bearing was far worse than the other, so the shaft would turn in an
ellipse. Nothing can be done about that, except replace the bearings,
which would've cost more than what I spent on the grinder in the first
place, and I would've still have to replace the wheels.

I now have a 10" Wilton Grinder that I bought from a local tool
shop. Even on sale, it was expensive, but well worth it. It runs as
smooth as silk. Out of the box, it had very little vibration, and after
taking a small cleanup pass with a diamond dresser, it ran even better.
I haven't found anything that would bog the motor down, even with some
fairly aggressive grinding.

The grinder was made in Taiwan, not China, so the level of
craftsmanship it just a tad better.
