it's time for another refix tool review and today we're looking at the WIHA Picofinish electric
precision screwdriver set well done who comes up with these product names that was a mouthful
well the product might be a mouthful to say but we've had these screwdrivers out for the last
four or five weeks in the actual workshop and we absolutely love them gordon they do and you
know precision gary what do you think first when i think precision what comes to your mind well i'm
gonna have to slip the spectacles on because i'd imagine we're going electronics yeah and
that's what we're happening more and more in the electrical industries electronics are creeping
into installations and as it creeps in terminal sizes shrink and possibly you need a smaller
screwdriver set to properly get to those terminals yeah don't want a really long screwdriver when
it's mounted on a PCB board you might get the torque set and pop it off yeah you know you can't
use these gary for levering painting lids off poking around in the building fabric you're trying
to locate those cables or joists well the keynote amongst you might have noticed we've already used
these screwdrivers in a previous race so let's cut to that little bit of footage so this is when i
destroyed the Speede 2 with my uh screwdriver i think you just destroyed your wrist in that
video gary if i see remember right if you haven't seen that it is an absolute treat to watch that
you will see where you can and can't use this screwdriver but yes that was yeah it's one of
those applications in din rail terminals but perhaps if you're not doing quite as many as
it were in that race no so where have we been using it and where we found it brilliant to use
okay so the first thing we think about is dimmer switches so we've been doing a series recently
looking at dimming leds and we certainly found that most dimmer switches in the uk
installations have small terminals so what did you use in that one gary yeah i used a 2.5 mil uh flat
screwdriver in order to facilitate the terminals in the back of that dimmer and then I went on
and i actually did the back of a dimmer that's slightly different this time what do i use it
for now yeah so you'll find that a lot of dimmer switches also have a potentiometer in the back
again that's a quite a sensitive electronic component which needs a precision screwdriver
to yeah not damage it as you're setting the dimmed level yeah so we use that screwdriver
just to bring the low end of that dimming lamp down so again a really good use of that tool
so what else have we been doing with it well we've been we'll also found that recently more
and more uh euro modules now we have this small euro module that's a usb charger we did and again
that's got small terminals on the back of it it has and again you can see the electronics through
the green that you obviously wouldn't want to be wrenching against those terminals this screwdriver
works a treat for that let's have a closer look at when the screwdrivers because there's another
little uh nice touch to it as well gordon so you want to pop that one out for us well it's two
if you want to hold it steady and try and get some speed up yeah yeah you didn't do that in that race
but that's what you should have done i did win and you'll also notice on the top so look the size
of the screwdriver is nice and clearly printed on the top okay yeah which can be a bit of a problem
because if you look at the smallest screwdriver in this range it's absolutely tiny it is where
would we use that sort of screwdriver that really really small screwdriver oh I think uh the best
one for you gary's using it to repair your glasses all right okay yes so the only problem i find
is when you're making a repair to the glasses you probably need the glasses on in order to be able
to see the screw head so that's one thing i do find was a little bit of using the force there in
order to do so yeah so there's that and then also we're starting to see small terms on things like
smart thermostats yeah we had a look at a Nest thermostat in a lot of our ferrulel videos yeah
um but this we found a little small phillips head screwdriver fits incredibly well into the
terminals you find in the nest yeah and then also more recently we used it on the Myenergi Eddy
yeah when we opened that up that was full of green PCB boards and the glasses were slipped on nice
and early there in order that we can make those connections yeah so in there they have some very
small terminals for the current transformer that uh yeah has a couple of cable connections to those
and that's possibly the thing about pcb terminals the fact these are a small screwdriver means
you're less likely to sort of should i suggest over torque them and wrench the pcb terminal off
the circuit board and when you say small you mean physically in length small don't you yeah i mean
that's it yeah so that's yeah ideal i mean and i've had a set similar to this for a long time
that just wasn't insulated actually oh right okay yeah okay now we also saw some screwless din rail
connections made by vargo or Wago depending on how you want to say it and they came with
something that they described as not a screwdriver let's bring the camera in to not look at this
screwdriver so that is not a screwdriver provided by waygo no it's an operating tool gary with a
partially insulated chef can you just demonstrate what that was used for for me okay so i just you
push that into these screwless top job din rail terminals okay and then you can put your conductor
in with a fair alarm release and take over here okay so that was using a partially insulated
operating tool operating tool got another lovely name but we thought that maybe these screwdrivers
could be used for this as well yeah a surprise surprise yeah even though this is a screwdriver
not to be mistaken for a partially insulated shaft oh right they work a treat as well it does
exactly the same job so so yeah so so could we say that we could use the screwdriver on a screwless
i like connector yeah that's why they can't call that a screwdriver yeah you might be able to
use it to poke around in the roof to find joists okay any other places you want to take us with
a screwdriver set um so the other thing it comes with i mean you like a pouch gary don't you i do
now when i open up my pouch and i had a look earlier on the smallest tip on mine was 2.5 mil
and then that was it really i jumped straight up then to a larger size one
and that tip being um let me have a look my eyesight's not great with glasses on that's four
millimeters so yeah i've got two point five and four so this set starts at three millimeters and
goes all the way down to 1.5 which is the tiny one you use for your glasses also comes with two
phillips a phillips double zero and a phillips zero okay so whereas this pouch is ideal perhaps
electrical contractor and that's why i really like it actually when we start looking the electronics
aspects this screwdriver set isn't adequate and i'm probably gonna need another one it also you
can mount it so there's a couple of little fixings here so if it was used in a workshop okay it can
be mounted a little bit of a drawback i would suggest is that the sizes of them can be seen
but you'd have to mount it really high in order to look underneath yeah or upside down upside
down yeah maybe you could have mounted it upside down you can see them there but unfortunately the
trade enders you can put your little screws in or probably the ones you lose anywhere um yeah
you can yeah that wouldn't work would it not quite and what i also like about the tray is that in all
the time we've had this set we have been very keen to return them to the tray and we've got them all
i think if they came separate we were about to have been hunting around uh the studios in order
to find the rest of them that's a fair point yeah but if you were on site it might be nice to have a
pouch oh yeah it's always nice to have a pouch if you're on site i would suggest and i love a pouch
so the screwdriver set here from we hub which you're going to remind us of the name it's the
Wiha Picofinish electric precision screwdriver set okay so when you're asking your apprentice to go
to the van you'd ask him to get what gordon the take off Pico inish electric precision screwdriver
set okay maybe the small screwdrivers on the stand but maybe what you'd be asking for but we
think they're they're perfect for what we've used them around the workshop for these electronic base
terminations especially on our dimming series and the stuff we did with my energy as always we're
interested in your screwdriver stories what's your go-to set when you're working on precision
stuff we're not using them for knocking holes in ceilings when we're making those electronic
connections please leave those comments below and we'll try and get back to as many as we can
