[Music]

I'm Kenny from pro tool reviews and

today I want to talk about one of the

tools that we use a lot in the field

whenever we're cutting corrugated metal

or metal roofing that kind of stuff

it's the nibbler we're actually using

the Trump true tool n 160 lithium ion

it's a cordless model and what we see a

lot of people doing in the field is

they're using grinders jig saws

reciprocating saws metal cutting saws

even power cutters and a lot of it is

because these tools are now cordless or

in the case of the power cutter you've

got gas and cordless options but the

nibbler is just now starting to go that

direction so we're going to take this

12-volt Trump nibbler and see how it

compares to some of these big 36 volt 18

volt tools and just see if we can do a

better job all right so to start we're

just going to do a straight cut we're

going to try to follow the cut line that

we've got in here

we'll start with the jigsaw and we've

got a metal blade orbital actions off on

this let's just see if we can follow the

well

[Music]

all right so same thing and let's take a

look at what happens if we use a

reciprocating saw

[Applause]

[Applause]

[Applause]

all right not too bad not great and then

let's go to a grinder this is probably

one of the more popular ways of cutting

that we see in the field

[Music]

[Music]

[Music]

all right lots of sparks that one

actually looked a bit straighter than

the others and then let's wrap up with

our nibbler here yeah I'm going to

switch sides and push this away from me

a little bit different cutting action on

this

[Applause]

alright moved off a little bit at the

end alright alright unpack what each of

these saws did now we started with the

jigsaw and it actually did a pretty good

job of allowing me to follow the cut

line but what I ran into was as I would

come up and down through the grooves

here I would really start to drift the

blade would wobble on me a little bit

and I was drifting left and so following

the cut line wasn't terribly easy it

wasn't a ton of vibration and this this

was definitely the right blade for the

job it was just a little bit difficult

to make a really accurate cut and then

same thing with the reciprocating saw a

little bit of blade wobble left me

wandering some and even though this has

a pivoting shoe on the front as that

would get into the valleys here in our

material I had a hard time maintaining

good contact and that was adding some

extra vibration to the cut and then just

the angle I was having to try and work

it and still see my cut line that was a

challenge for sure especially like I

said in that valley it was losing

contact and losing my sight line the

grinder did a pretty good job this is a

6 inch grinder wheel that we've got on

here and it'll it tracked really well it

left a better edge the biggest issue

with this was really just the amount of

sparks that it was throwing it was

really hard to accurately follow that

line and then with the nibbler what was

really nice about it is because I was

able to to turn this 90 degrees I was

able to really work up and down with the

material waving along with it as I went

it sounded a lot quieter than the other

ones had left a nice edging you can't

see right here on the end I did wander a

little bit on the back into my cut but

my visibility was a lot better and I was

able to track it pretty well so that's

one type of cut that we're looking at

let's move on to a couple of different

types of cut outs that we might come

across in material like this instead of

just being able to cut the whole thing

off alright so we've got a little bit

different material here it's got some

higher ridges on it and we're just take

a look and see what some of limitations

are as far as the depth of cut of some

of these tools so we'll start with the

jigsaw again and just see if it can

complete the cut

[Applause]

[Music]

[Music]

[Applause]

so you can see there as I go into this

valley I'm totally losing my sight line

because of the distance between where

the blades actually cutting in the shoes

in my way and as I tried to come back up

the blade came out popped against this I

could probably finish this cut and get

away with it but clearly not ideal let's

see if the recent saw does any better of

course an advantage here is that you can

get longer blades or the reciprocating

saw than you would other types of jig

saws so let's see what happens we'll

start over here and kind of pull cut

toward us

[Applause]

all right we made the cut

it's actually a lot straighter than I

thought it was going to be but clearly

coming up these ridges introducing a lot

of vibration the saw the teeth are

actually trying to grab a hold and and

doing some funky stuff the worst part

about that was just how much vibration

was in that we were actually shaking

some stuff off the table which isn't

cool so again this is capable you can do

it it's not something that I really want

to be working with if I can avoid it

now see that if we can do the granite

now this is a 6 inch grinder switching

insta Grindr wheel we've used it a

little bit so we know that some of the

materials come off but let's see if it's

able to to maintain the depth going

through there

[Music]

[Applause]

[Music]

all right barely barely made it through

that again good straight cut the grind

is really good at tracking through this

compared to some of the other tools that

we've been using a lot of sparks sight

lines kind of hard to follow we'll get a

decent cut and again so that's good but

again the six-inch grinder if you've

only got a four and a half five inch

grinder you're not gonna make this cut

so finally let's wrap it up with our

nibbler and switch sides with you here

all right so let's grab our nibbler and

we're gonna we've got it turn 90 degrees

so that we can go with the peaks and

curves and see if this is a better

solution

[Applause]

[Applause]

yeah so if I had a cut line on here what

a devil been easy to follow I was

clearly moving a little bit as I made

that cut but some vibration not nearly

as much as the reciprocating saw no

sparks being thrown around on that I was

able to just kind of ease in and out of

each peak in valley so that made it easy

and even this there's enough there's a

so little vibration and and and a

relative torque or anything like that in

here that I really could just take one

hand off to help me if my handle is

getting in the way end abuse so the

grinder had some great advantages here

and it's its speed and the and it's

tracking but the the nibbler I still

like that better for its noise reduction

no sparks and better visibility on that

okay so let's take a look at a couple

different other types so we've got kind

of a curved cut out that we need to make

here but on top of that we don't have

the advantage of this material being

clamped down so we're cutting it in the

field and we we've got to use one hand

to cut and we've got to use one hand to

secure the material so let's just see

what kind of characteristics we get out

of this and I can already see starting

with this jig saw I'm having to come in

at an angle see if I can even make that

curve

Hey look at that alright so trying to

come into these weird angles and stuff

like this the blade actually jumped out

of the track on this saw so it was going

to be capable of finishing off that cut

but it's not something I really want to

do is trying to I was fighting it a lot

trying to make that happen and and even

looking at the blade here I mean it's

just it's bent now so how useful it's

going to be is pretty debatable all

right so let's try the nibbler again I

got to use one hand to cut and I've got

to use the other hand I'll secure my

material on this so

all right said just a little bit of

cleanup I need to do right there where

adds a little trouble getting in and it

took a second to get that that turn it

was a little bit tighter of a turn than

it wanted to do on its own I was able to

make it and this is a reasonable curve

it was clearly able to do the cut that

could cut with one hand hold the

material with the other and I mean this

particular tool is a 12-volt tool 10.8

volt tool is it's lightweight enough

that you can make those kinds of turns

really work your arm around and of

course if I'm not trying to to show all

this on camera I could actually

physically move from side to side to

make a cleaner cut if I wanted to but as

far as making that kerf cut out goes

clearly the nibbler is gonna be your

best option there all right so one last

cut I want to take a look at is when you

need to do a complete cutout now a

nibbler is not capable of doing any kind

of plunge cut so I actually attempted to

draw a circle here it kind of looked

more like a strawberry so we're just

going to own it but let me show you how

you're going to make that cut now you're

going to start with the easiest way to

do it is with a step bit just make sure

that you cut to the inside of of your

hole so that you don't take out any

material that you're trying to keep and

okay nice fast step bit there mmm love

that smell of oil once you've got that

going now you've got an access point and

you can can work the nibbler around I'm

gonna once again change my angle here

because I can and it's gonna be a little

easier this way all right take it all

off all right

[Applause]

all right now we have a beautiful

strawberry shaped hole here I said

obviously there's a lot of different

ways you can cut metal corrugated metal

roofing that kind of thing and some are

better than others now what I really

like about the nibbler why we use it

instead of some of these other ideas is

just simply you've got no sparks that

you're worried about it does cut very

very quickly and you get you can follow

an edge well it's just a great tool it's

the right tool for cutting this kind of

thing you're trying to do a reset saw or

a jig saw and you're getting into a tool

that's really not designed to do that

the grinder works well but it is limited

so anyway if you have any questions

about that feel free to leave them in

the comments below if you like this

particular nibbler it is the true tool

160 lithium ion who's from a company

called Trump who makes these and this

kit does come with two these 12-volt

batteries so as always thanks for
