hello and welcome to this review of the DeWalt DCD 998 drill we're going to put
this drill through its paces tell me what we think about it and also try a
variety different materials including concrete blocks and wood. We're also going
to compare it with the older DCD996 that it replaces show you the
differences you can see one of the main ones here is it's got a massive handle
the other one is that it also has a new feature called power detect the Power
Detect feature when coupled with a bigger battery like this 8 amp hour power battery
rather than with a 5 amp hour battery gives it 29 percent more power and we're
going to just show you exactly on how that works so here is the DeWalt DCD 998
drill this replaces the older 996 and we'll be putting those to a test later
on showing you show you the differences the main one is is this power detect
feature there when you use one of their bigger 8 amp hour power batteries that you
can see pictured with it it bumps up the power from 820 watts to a 1072
still fully compatible with all the smaller batteries a 2 amp hour and 5
amp hour and the Flexvolt batteries all work in this drill and but you will
need one of these 8 amp hour batteries in order to get the extra power out of it
it has 11 different clutch settings it's an electronic clutch as well as the
hammer action setting on it if you can see there that there's the reverse
forwards and backwards for the trigger and also hold you can hold it there
again so it doesn't actually go off in your tool bag yeah we just go through
the different clip settings you can hear actually as you go through it speeds up
as well as the actual speed control change in the speech so does the clutch
this is the LED light now the first setting is the lowest brightness and
then the second one is medium but then the the final one is not just a higher
brightness it also will stay on for 20 minutes so you can use as a torch and
you can see here it really is quite quite good it's quite powerful just as a
torch so very useful if you working a low look at low-light conditions so also
supplied with the drill is a belt hook now I'm personally not a fan of these I
don't ever use them but I can see what some people would offering and I end up
knocking it off my belts and they falls on the floor
because he just screws on here and each side of the drill and this is common
with a lot of Dewalt tools has the these two fixing points for different
various different accessories and now certainly they don't actually well in
the USA this USA model that we thought that actually and clearly thing for
holding a screwdriver bit but you can buy these in the States
you can get these these are actually official to Walt
that parts yeah I've had to import them it myself and there's a far superior to
the magnetic ones I always find that magnetic holders don't hold well enough
and you end up losing your screwdriver this there are some as well you can get
the slide in but they're a little bit less convenient than this these type
types that actually where it clips in
you can see though the part number so this is the ATM power between just as a
comparison you can see there the five amp hour battery now one of the
questions that might be asking if you've got older toolkit which I certainly do
is will this work with the slide on adapter for the older battery star these
adapters are only available well they're not available in Europe here I've had to
import these but no you can see it doesn't actually fit in the am battery
you can get them on eBay but they tend to be all forgeries or fakes you don't
actually get the genuine ones well I'm not here in Europe some a very
convincing fake so you can telogen spy the screws now one thing it does work
with is the slide on USB adapter certainly there's any outputs in 1.5
amps it would be nice if they actually applied a bit or even better if they
produced a new one with USB C and and power delivery on PD not to be confused
the power detect but power delivery secret charge up something like a laptop
now here's the to drill side-by-side the 996 dollar you can't see that the actual
casing is different there's different number of holes there also around the
trigger the grip is different as well so it is it is a different casing either
they look very similar that there are differences
now we're going to move on to a concrete block test we can use a six millimeter
brand new batter all extreme masonry bit and we're gonna try it just to keep it
fair we're going to keep it but in the 996 first so it's brand new unused bit
so 6.1 seconds there with the DCT 996 and five-hour battery now we're gonna
try in the new DC t98 with it with its eight and power battery
that's four point three seconds so on the face it a lot quicker now we'll just
try in the nine eight wither with a 5 amp hour battery
still quicker I mean obviously there could be differences in the block but
there was definitely a difference there between the two two drills and the two
batteries as well so but more and more maybe at one that's more revealing is
with a wood wood Tesori this brand-new mill Milwaukee thirty two millimeter
flat wood bit again 996 first
17.7 seconds now the night with a 5 amp hour battery
7.90 a lot but yeah that's quite a different day and now with the Asian
power battery
seconds with the and power battery now we're going to move on to the player
detect feature and try the DC d9 innate with a few different matters now we get
to try it with a flex or battery here that was a lot slower so unfortunately
the power detect does not work for the thief let's go back saying that if I
don't know just back to the a just here speak much faster now we're gonna move
on to taking apart the DC d no no no no I bought a sets of these long T talk a
bits I need they're quite the length to be
able to get actually to a couple of screws and I don't mean bear got this
for about seven dollars the really nice expensive first thing you need to do
IRA's to cut into the label or remove the label I've been cutting except I
don't think he'll probably stick back on again if you peeled it off there's three
different labels actually need to cut through this one there and then there's
one here that shows you the light indications and one at the bottom and if
you don't do these then you will struggle to get the in casing apart they
they join where whether to part of the sort of clamshell join together so he's
taking apart I'm gonna use a deal Walt electric screwdriver well there are
twelve volt range which is quite handy and just the job pretty quickly this one
has a variety can talk settings so it's five two doing this sort of job you can
set the talk very low because then it means we don't that tightly being
plastic you do risk if you over tighten and putting it back together did you
risk actually the threads on the actual plastic so
that's quite a few screws to take out
now the the Chuck on this is it is linked to the clutch and the gearbox
it's all in one unit at the front that metal bit the back the back of it where
all the electronics are on the motor are all in inside this the plastic housing
at the back
so once you've taken out all these smaller screws they were all they are
all the same length apart from this for the full screws that holds the actual
gearbox assembly to the to the back plus a bit so these these are bigger but
they're obvious which ones of which they to come out there you can't get like a
longer extension there if you want fully light now by I found just a slacking to
it still but still fine to take the bits out now it comes to taking it apart you
just require a little bit of prizing apart but not not too much so I punched
opting for a small electrical screwdriver that you could use a proper
Preiser I didn't actually mark the case doing it so it's very tough plastic
housing so this isn't sort of chew up like a lot of things would and you just
need to just go around and just separate it out of it then to actually get the
whole thing parked you do have to actually pull the this off front
assembly slightly out just just lift it apart like that
and it should start to start to come away it does have a huge sort of metal
pins as well that hold it together so they can be a little bit stiff also just
check that you know that you've got all the way through the stickers and then
just pull pull the front assembly apart and then it should should start to
actually come to bit and you can see why that little metal pins there but there
we have have it inside there you can see all the different all the bits and bobs
there inside there there the motor being at the top at the back and it's a very
similar looking motor to the motor on the 996 the DC 906 but it does actually
have a different part number on it so they are they are separate so just bring
the 99016 just to show you the difference there's a lot of similarities
in there as well but you can see there are some differences and here's just a
close-up shot of that motor and all the internal bits around the the trigger
there and the the reverse and forward and hold switch that safety switch this
stops the motor going if you've got unit in a tool bag of some of that you can
see the system this is my older 996 I've been using for the last four years or so
so it's a bit mucky inside whereas this is a brand new the 998 but you're very
very similar design but obviously some changes there and you can see that a
different different part number on there on the motor and there's some of the
other changes it looks like is running inside four different components it it
must have somewhere some secretary that does the power detect for actually
detecting which battery you've got it so that pretty much wraps up we'll just
move on to the pros and cons pros of this drill their power and speed of the
drill is very impressive as I was yeah I didn't think there'd be that much
difference between the old on it six actually there is also a it has a great
battery life from you know they say amp hour battery
you know I've already used it for a few little jobs and you know how that's
charged the battery here the LED light the same is on the 996 very bright very
handy very useful its position is very useful as well being angled upwards at
weather where you're working rather than being next to the trigger
because that tends to just cast a shadow there whereas at the bottom it does
really really really helpful to see the handle also not not what's pictured in
this promotional pictures actually a shorter handle that is what you get when
you get a very long handle very good if you if you do so here it is this is
liable to sort of jam or you've got a lot of talk you know I'm all the lower
torque settings but yeah much appreciated also its metal now the
previous 906 was a plastic handle cons well disappointed that it didn't work in
its power detect mode with it with a flexible battery the nine upper battery
it's going to supporting you know I've got a few of those myself and I've got a
few folks hot tools but it would have been nice if they'd have worked with
this especially if you're buying this without the battery but as it is if
you're the extra power you're going to have to buy one that is suitable for
about detect and so forth any battery that we know of that does is this a
temper we don't know there is a six on power as well in the states and neither
of these are available in the UK Europe at the moment it's not a sort of stops
at five amp hours it doesn't go up to a six or eight and now she use the flex
felt which as we've seen doesn't doesn't go any faster
they knew the negative I can really say about this drill is it's insanely noisy
but I mean that goes with its you know it's got a fantastic hammer action on it
and it'll make a lot of noise how can your drilling through a hard mature
