Harbor Freight has a tool and cutter grinder on sale for $119.95.  It
has two tiltable tables, and is set up to spin two face mounted
silicon carbide stones. It probably weighs in at 60 lbs.  Heavy.
Motor is reversable, 1/2 horsepower.

Anyone been brave enough to try one of these? Sale lasts until the
23rd.

Do you know the manufacturer and model number?

A friend of mine got one about 6 months ago. He really likes it and he put
on diamond wheels. I will probably get one soon after seeing his.

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 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. Mine
has plenty of power for its intended uses, is very quiet, and takes
*minutes* to coast to a stop. In other words, the bearings seem to be
pretty good. (I tested this in the store before buying it.)

The wheels that came on mine were white aluminum oxide, and they
seemed pretty decent for Chinese wheels. But mine is not reversible,
and has a 1 hp (nameplate) motor. If the HF machine is reversible,
that's a plus, and if the 1/2 hp is honest, it may be enough. If you
can find one at a HF store and hear it run before you buy it, that
would be very helpful. It should be smooth, quiet, and have a very
long coast down time. If it doesn't, pass.

I just bought one. It seems 'OK'. It's VERY much like many other
imported carbide grinders on the market, and may be identical to some
others. The castings look decent, and the machining on the tables is
'OK'. It comes with two 'green' Si-Carbide wheels (some others come with
white aluminum oxide wheels). The $119.95 price convinced me to try one,
as most of the other imports are more like $230, and even HF's normal
price is something like $160.

One point ... all the fasteners on this unit are metric (may be true of
some others as well). The***quality is questionable, and many should
probably be replaced (typical of import tools). The wheel mounting hub
is 1.25" as is normal for such machines.

The wheel guards (integral) have *VERY* little clearance with the
wheels, but it *WILL* take a true 6" steel backed wheel. I bought a few
white aluminum oxide wheels for it from KBC. The KBC wheels (listed as
6") are actually about 6-3/16" diam. (stone, not steel back), and will
NOT fit the HF grinder without modification. I mounted one of the
oversized wheels on my surface grinder and dressed off the surplus
diameter. NOW it fits fine.

I've only used it for a couple test grinds so far, so how the motor and
bearings will stand up remains to be seen. It's reasonably quiet
running, no worse than several other bench grinders I have. My use is
not heavy, so I expect it will be 'OK', especially considering it's cost.

I picked up a 1" belt/6" disk sander to take the place
of the grinder and have -loved- it. The local ToolMart
beat the local Borg price.  (std disclaimer)

Gary;

What is the purpose of the grinder being reversible?   What
can you do with it running in reverse that you cannot do with
it running in the forward direction?

Thanks,
Pete.

Ordinarily you would grind the left side of the tool bit on the right wheel
and the right side of the bit on the left wheel.
If the grinder was reversable you could brind opposite sides of the bit on
the front and rear sides of the wheel. That way you could put two different
wheels on the grinder.

That makes sense, thanks.

For one thing, it allows you to grind on the BACK side of the wheel
(face), which is easy since the table covers the entire width of the
wheel. This may be desirable with some tooling, as more of the table
surface may be available for holding or steadying the workpiece, or
keeping it against the miter gauge.

I've not had this type grinder long enough (five days) to decide how
useful that may be.

Which is what I've done, leaving the original 'green' Si-Carbide wheel
on one side (for Tu-carbide tools), and mounting a white Al-oxide wheel
on the other (for HSS).

By the way ... there's an interesting ERROR in the HF instructions,
which tell you  how to grind on the outer rim of the wheels (like on a
bench grinder) instead of the faces. *NOT*!   They are planning a
revision of the instructions (as of 6/17/03).

With the steel backed wheels it is correct to grind on the wheel FACES,
not the rims.

Are you talking about this one here: HF Item# 46727-0VGA
from Central Machinery Industrial? I see it on their web for 159.99.
My latest sale catalog "Summer 2003/ Catalog 563-K" shows it at $149.99.
Where did you see the $119.95 price listed at?

'In store' special at the local stores, limited quantities. The cheapest
I've seen them in the HF mail-order catalogs is $139.95. Price varies
from month to month ... anywhere from $140 to $180 ... typical HF
practice. The $119.95 price is by far the lowest on this item that I've
seen. I haven't found anything really wrong with mine ... knock on wood!
It looks the same as other selling for up to twice the HF price.

I had exactly this same question.  Then I called the local store, and they
quoted $119.95.  I don't know if that helps if you don't have a store near
you.

   Thats the main reason for having the reverse on the motor, it's a lot
easier to get at the backside of a tool by using both sides of the
wheel. but you always want the wheel to be going down into the tool.
   Typically we use a SiC green wheel on one side and a diamond wheel on
the other.  This is assuming you are only doing Brazed carbide tools. If
you are doing HSS then a coarse alum oxide(grey or black) and a fine
white alum oxide on the other for finishing.
   A good idea is to make a diamond dresser to run in the table slot to
true up the wheels.  gives you a nice flat surface on the SiC and AlO
wheels(not on the diamond)

here is a link to the original baldor version, much more expensive :-)
