Mighty-Seven
NC-6266 3/4”
Impact Wrench
The reviewer says this tool is lightweight
and quiet for increased user comfort.
By David Brierley, Managing Editor
When using a tool
such as an air
impact wrench on
multiple projects per
day, every day, it is
important for the technician
to be able to maintain
some level of comfort.
Phillip Huffman, manager
at AAA Car Care Center in
Greensboro, North Carolina,
found that he could comfortably
use the Mighty-Seven NC-6266
3/4” Drive Composite Impact
Wrench day aft er day.
One of the major factors contributing
to the air impact wrench’s
ease of use is the lightweight
design. According to the manufacturer,
it weighs 6.5 lbs.
“Th is air gun is so much lighter,”
Huff man says. “My other 3/4” air
impact wrench weighs about 4 lbs
more than this one. So when using
this for a long time, this air gun is
much easier on your hands, arms
and back.”
But being lighter in weight does
not mean that this tool is light on
power, according to the reviewer.
“Th e power on the M7 is unbelievable,”
he says, adding that it
has all the power that “a 3/4” air
gun should have.”
Another factor contributing to
the air impact wrench’s usability is
its sound output. “Th e sound level
is one of the best that I have used,”
Huff man says.

Impact Wrench, No.
NC-6266, offers 1,500
lb-ft of maximum
reverse torque. This
tool weighs 6.5 lbs and

degree swivel air inlet

He notes that the
sound level is much
better than that of the
other 3/4” air impact
wrench he regularly uses.
Huff man also says the
length of the tool makes it
easier to maneuver and fi t
into tight spaces.
As far as setup goes, Huff man
notes that changing the air fi tting
to match the shop’s system was
all that needed to be done. Aft er
that, the air impact wrench was
ready to use.
Included in the box is a user’s
manual and warranty guide.
Huff man used the NC-6266
on bus lug nuts, and noted that it
“also works great with crankshaft
pulleys and everyday shop use.”
Th e only potential improvement
that the reviewer noted
would be to add “impact rubber
around the front and back of tool.”
Overall, Huff man was impressed
with the NC-6266’s lightweight
design, its quiet operation and its
ample torque.
