a

Choosing Your Drill Press

looking for a drill press these are some

of the things that you need to look out

for

[Music]

[Applause]

the first thing you need to do is look

at the size of the head of the drill

press now the reason you need to look at

the size of the head is that'll

determine the capacity of material that

you can work in there are two important

sizes to consider when you're looking at

the head of the drill press the first

one is the swing and the swing is the

distance from the center of the drill

truck to the back of this column now the

swing will determine how far you can get

into a workpiece when you're talking

about the swing it's usually provided in

inches so for instance this one here's

17 inches or about 425 mil whereas this

one here is 14 inches or about 350 mm so

that governs how far you can go into

your workpiece the next thing you need

to worry about is the travel and the

travel is how far the spindle

controllers down now for a model like

this you're in 120 ml for a model like

this you're looking at about 80 ml and

you can see here there's a difference in

the height of the head here and here so

the spindles contained in the in the

head and that determines your travel

[Music]

the next thing to consider is the number

of speeds that the drill press has these

days most of your bigger models have

twelve or sixteen speeds in the case of

this one this has twelve speeds that

runs from 150 up to 24 50 revs per

minute

this small model actually has 16 speeds

but the usable range is 222 28 40 so

you'll find these days with most of the

drill presses up that are on the market

all but the very smallest ones will

either have 12 or 16 speeds which is

more than enough for most applications

you're really small bench top models

will only have 5 speeds and then it's

generally not an issue for your smaller

drill presses because they can really

only work in a very smaller capacity

anyway and so those speeds of a

well-suited to that size of drill press

one thing that's important to note is

that with all the Sherwood drill presses

they come with a micro switch now what

the micro switch does is it prevents the

machine from turning on while this

covers open which is just an extra

safety feature that the Sherwood's have

got so with the cover back down again

the micro switch engaged the drill press

can turn back on

[Music]

now as you go up in the size of the

drill presses one of the major

improvements that you get in going up in

the sizes is the size of the motors so

it's it's pretty self-explanatory as the

drill presses get bigger so does the

capacity of the motor one of the great

benefits of the Sherwood drill press

range is the fact that all of the motors

are four pole motors so they run half

the speed of a normal motor but I have

twice the talk now when you're talking

about drilling one of the most important

factors with drilling especially when

you're working at low revs is to have

high torque and one of the great

benefits as our Sherwood is that these

are all high torque motors from the

smallest one all the way through to the

biggest one

[Music]

so when you're thinking about a drill

press there's the issue of the the

capacity in terms of the size that can

it can work with one of the major things

to think about is the size of the drill

bits that you're going to be using and

in what materials and that may also

determine what size motor you need

something else to consider with choosing

the right drill press is the capacity of

the chuck with the standard drill press

like this this sort of chuck heel and

hold bits from 3ml up to 16 mil your

smaller drill presses will come with a

smaller chuck say one to 13 mil and you

can also as you go up in size to your

larger drill presses this one here will

go from 5 to 20 mil it's important to

think about that because this because as

you go up in the size of the chuck the

minimum size that can hold also

increases as well so this one here that

say a 16 mil can only hold bits the down

to three millimeters you can look at

something like a keyless chuck a keyless

chuck here this is also a 16 mil

capacity but it can hold down to one

millimeter

[Music]

the other thing to consider is that as

you go up in size of Drew press the

Morse taper gets bigger as well so from

the smallest up to this size of drill

press in the show would range it's a 2

Morse taper that's what that's what it

looks like there as you go up to the

bigger sizes like this one and the next

one above it the Morse taper size

increases now that's important because

that's the part that actually sits

inside the spindle of the drill press

and you need a good amount of mass

between the Arbor and the spindle of the

drill press and that absorbs the

vibration one of the enemies of drilling

accurately is vibration

[Music]

sometimes when people get home and they

put their drill press together you can

have the problem where the Chuck keeps

falling out of the spindle the reason

for this is because there's a small

amount of oil that's left on the on the

Arbor and also inside the spindle the

quickest and easiest way of fixing this

problem is to get a piece of wet and dry

quickly rub it over the arbor and then

also get that same piece of wet and dry

and put it up the spindle and give it a

quick rub in there then when you see the

arbor into the spindle it'll grip a lot

better

now of course as the drill presses get

bigger some of the other things on the

drill press get bigger as well the

bigger the drill press obviously you get

a larger base the post is a bit bigger

so that gives you a bit more support for

the table prevents it from rocking back

and forth

you obviously get bigger tables as well

you'll see here this one has markings

along the top that's because on pretty

much all drill presses now you can

actually tilt the tables so if you need

to go in at a particular angle you can

just tilt the tables so there's usually

a small bolt underneath the table and

you just loosen that off and then you

can tilt the tables so when it's time to

start thinking about buying a drill

press start thinking about the types of

material that you're going to be using

the size of the drill bits that you need

to use and also think about maybe future

proofing so that you can get the right

drill press that's going to last a

lifetime

we've got a great range of Sherwood

drill presses a timber con and we're

sure to find something that'll fit your

needs
