a common problem with tap tools is that
they get stripped so here we have a
balls as you can see that screws insert
tsveti doll perfectly but the center
although the actual threads have become
stripped of it so you've got two choices
when that happens you can use the next
ball size up so you can drill the oil
slightly larger and put a larger tub
through it and then use a larger bolt or
you can use a thread repair kit so today
we're going to use the thread repair kit
so this is a basic kit probably the most
common make of these is le coil most
people seem to avail of doors so this is
the m10 kit so what we get is a drill
bit as the correct size the tap that's
the correct size the thread inserts are
the le coils and then the two tools that
we use are putting the other coils in so
normal it's an absolute piece of care
using these and they're extremely useful
so the first thing we need to do is
drill the actual all using the correct
size drill bit that's in the kit so
before we go any further we need to make
sure we've got our safety glasses on so
I'm just going to drill the all out to
the correct size using this drill bit so
now we've got the correct size all for
our tap that we're going to use next
so I'll just fit some cutting fluid on
there and then we can get the all
started
so we need to get the old straight
obviously so I'm just going to keep
checking it so I can see that that is
going in there straight so we just need
to tap the oil now so I'm going to work
a couple of turns forwards and then
watch a return back to be a chip off and
now we've actually gone all the way
through the material so why not straight
to actually import straight through so I
can then clean that then we can put our
back in the kit so now we take our
thread insert and we're getting the
correct way around which is that where
and then we use the Andal so we put that
on the actual tang on the inside there
and then we screw that into the all that
we've just made
and we need to keep screwing it in and
so it gets alpha turn below the surface
of the metal which is about there so now
the final two when the kit is the punch
so we'll just push the punch in and
Brits hang off and I snap the tag off
from the other side of the oil so I want
your thread inserts in place you can
just take your bolt and you can just
screw it straight in there so that's how
to use an le Cowell or a developer kit
