NEW F77 PowerDriver screwdrivers
"The Precision Screwdrivers of the Future"
Whoever said, "...a screwdriver is just a screwdriver", obviously wasn't a
Woodwind Repairman. Every Repairman knows that using the right screwdriver for
the job saves time, effort, and saves damage to valuable woodwinds and other
band instruments.
Ferree's offers a convenient new collection of specialty
screwdrivers designed specifically for the unique screws encountered so
frequently in the band instrument repair profession. At the same time, these
quality, semi-hollow ground screwdrivers are versatile enough
to be adaptable to many other uses, as well. Tolerances are kept extremely tight for the entire blade,
and the entire blade and shank are hardened for proper, maximum strength and toughness in a
screwdriver. Of course, all Ferree's screwdrivers are manufactured using the highest quality
steel, precision heat treatment techniques and state of the art design and
processing. Making all others obsolete.

just ordered the 2 new small longer versions.
"I wish I had had those screwdrivers years ago. They are so much
easier to use and they stay in the screw slot. The initial loosening of
a stubborn screw is easier to accomplish without damage to the screw (or rod) or
the post. Also the handles fit in the hand comfortably. They are a great
addition to my shop!" - Fred Heyburn, of Saxophred - Reed Instrument Repair, in Scio, OH.
FERREE'S NEW F77 "POWERDRIVER" SCREWDRIVERS
An all NEW precision ground radius gives the blade better fit with sizes to
accommodate nearly every woodwind or brasswind screw. The new superb fit, for
excellent control, which will also help eliminate slippage, scratching or injury. We are very
pleased to offer our new F77 PowerDriver's designed and developed by Ferree's Tools for
Repairmen who love solid, fixed-blade screwdrivers, that fit correctly and who take pride
in their tools and their workmanship.
THE TIP DESIGN & BLADE
We started with the tip of the blade, the part that has to fit
the pivot screw and rod end slots perfectly; which is the most important part of a Repairman's
screwdriver. The blade tips are then precision-ground to a semi-hollow
ground shape
to give them maximum strength.
The improved design, a parallel section, is then ground at the tip to
fit the pivot screw or rod slot properly through the full width and depth of the slot. This,
is what keeps you from buggering up the slot and post hole; a blade tip that evenly
distributes the turning torque applied at the handle to the full width and depth of the
pivot screw or rod end slot. The new bit end helps avoid having the blade
"cam-out" or "torque-out", which buggers up the slot. Many other alternatives have been developed,
but for the screw sizes we work with, this one IS the best option. {Other
alternatives being: Phillips, Torx, Pozidrive, Sockethead (hex), Robertson
(square), Tri-Wing, Torq-Set, Snake eyes (spanner), TP3 (triangular) and OPsit.} It is very important to keep ANY blade parallel to
the body to help prevent breakage caused by leverage created by angular insertion
into the post and slot, etcetera, causing undue stress on the slot and post hole..
PURPOSEFUL
ALUMINUM HANDLES WITH A REASON
Each NEW Ferree's F77 PowerDriver screwdriver comes with a black anodized
finish on a finely knurled aluminum alloy. The larger sizes have a 1/2" diameter handles
and 6" long blades
for more torque and easier turning of screws and rods. The smaller sizes
are available with either 3" or 6" length blades and
have 3/8" diameter handles to balance the torque with the smaller sizes,
giving you more precision, security and control than ever before.
Some Repairers may personally shorten these smaller blades to 1-1/2" or so.
There are 8 new screwdrivers in this series, the knob of each blade tip has
its own color for fast recognition. The #0, #1 and #2 width blades are 3" long.
The new slimmer
handles will be the same length as the larger ones, amounting for a total
of 1" more overall length.
The #1L and #2L blades are 6" long; all of these being for the smaller woodwinds. The #3, #4 and #5 width
blades are 6" long. All
of the comfortable, palm sized
rotating colored tops are hex shaped; so that the screwdrivers will NOT roll off your bench.

"...Reviewing your new screwdrivers. I think they're great and I actually
don't jab myself, since they don't slip out of the screw slots as easily.
Plus, I like the larger grip and top. The colored tops make it faster find
to pick up the right driver I want to use.." Sharon, at "House of M", Ohio

A note
on the 10 month anniversary of these drivers:
I had a fellow from California call and order an
additional #1 and #2 blade, for "spares". He said he loves them and knows
that someday he will probably break one and doesn't want to wait a week to
get a replacement when the time comes. He said you can "feel" when it is going break,
before it does. It is going to, like all screwdrivers. AND, thanked us for coming out with them.
He has Arthritis and
says they make it so he has no pain and can still work. He thought he was going
to have to stop.
These revolutionary drivers have been basically trouble-free so far, but, some folks just don't
realize that there IS a method and technique for using a very small, precision
and petite blade. The response overall, has been super
positive on these, for ALL the benefits they offer. They DO exactly what we
said they would do.
I guess, it was just in our excitement of coming out with
such a basic superior new tool,
we overlooked a couple of small considerations, which have now been addressed.
The body clearance on the one key of the flute
and the one place on the clarinet, for instance; and also that with a .012" blade, the 1/2"
diameter handle was just a little overpowering. The heat treat guy asked me, "Why don't you just give
them a wrench? (to turn the blade)". Although most folks realized that there IS a
common sense issue at play here and did not overuse the blade.
Additionally, I think the extra length will accommodate your concern of being kept
parallel with the rod or screw axis providing a more secure "hookup" at the slot and blade junction.
Lastly, the new small diameter handle will be the same length as the large
diameter handle and in the future all handles will be drilled to 1/4" less depth. This will provide for
about 1" additional overall length. What I have told a few folks is to cut off a 1/4"
long piece of 1/8"
diameter drill rod as a spacer or shim and place it in the blade hole of the handles you already have and that will
increase the overall length.
