You

now

own

one

of

the

handiest

drill

presses

avail·

able

for

wood

and

metal

drilling

in

the

home

work

shop.

The

quality

of

the

material

and

the

precision

ma·

chining

operations

are

controlled

by

rigid

tolerances

to

assure

accuracy

within

a

few

thousandths

of

an

inch.

The

rigid

steel

column,

the

sturdy

base

and

table,

and

the

massive

box

type

head

casting

enclos·

ing

the

operating

mechanism

are

designed

to

maintain

this

accuracy

through

the

wide

range

of

operations

which

may

be

performed

on

the

drill

press.

The

fully

enclosed

floating

spindle

design

does

away

with

the

projection

of

the

splines

at

the

top

thus

making

your

drill

press

a

safer-neater

appearing

tool.

This

feature

allows

you

to

change

the

to

the

various

or

even

remove

the

and

convenience

of

opera·

has

been

carefully

inspected

and

tested

at

the

during

shipment,

the

following

parts

have

been

packed

separately

in

an

enclosed

carton.

These

parts

should

serve

the

purpose

for

attaching

most

any

motor

of

conventional

design

to

the

drill

motor

mount.

INSTALLATION:

The

drill

press

should

be

holted

to

a

well

built

work

stand

or

bench

before

operating.

Three

11/32

inch

holes

are

provided

in

the

base

for

this

purpose.

To

install

the

motor

loosen

the

motor

mount

screw

and

remove

the

mount

from

the

drill

press.

Fasten

the

motor

to

the

mount

with

the

bolts

pro·

vided.

The

mount,

with

motor

attached,

and

tighten

the

mount

lock

screws.

For

normal

operation

the

large

step

of

the

spindle

pulley

should

be

in

line

with

the

small

step

..

'-,

of

the

motor

pulley.

Place

the

belt

around

the

pulleys

and

tighten

by

sliding

the

motor

mount

away

from

the

drill

press

head.

Tighten

the

mount

lock

screws

securely

to

hold

this

tensioa.

The

belt

tension

should

be

just

sufficient

to

prevent

slippage

during

normal

operation.

Excessive

tension

over-

loads

the

motor

and

places

unnecessary

strain

on

the

drill

press

mechanism.

DRILLS

AND

BITS:

Quite

a

variety

of

drills

and

bits

are

available

for

use

in

your

drill

press.

For

metal

drilling,

the

standard

twist

drill

has

proven

most

satisfactory.

High

Speed

Steel

Drills

generally

give

more

satisfactory

service

'for

com-

mercial

operation

because

they

hold

their

edge

longer

and

may

be

operated

at

higher

speeds.

However.

their

greater

cost

often

makes

their

use

in

the

home

shop

unwarranted.

Unless

extensive

metal

drilling

operations

are

plannea.

the

less

ex-

pensive

carbon

steel

drills will

give

satisfactory

servIce.

The

standard

twist

drill

may

also

be

used

in

wood.

This

drill

will

operate

much

more

effi-

--,

ciently

in

wood,

however,

if

the

point

is

altered

from

the

original

120

degree

angle

to

a

much

sharper

angle

of

ap-

proximately

70

degrees.

Most

any

standard

bit

may

be

used

for

wood

drilling

in

the

drill

press.

Slight

alterations

may

be

necessary

in

some

cases.

The

solid

monly

used

can

readily

be

reworked

for

use

by

filing

the

threads

off

the

point

and

by

cutting

off

the

enlarged

adapter

section

at

the

end

of

the

bit

shank.

The

Spur

Machine

Bit

is

probably

the

best

bit

for

wood

drilling

with

the

drill

press.

It

combines

the

best

qualities

of

the

twist

drill

and

the

standard

wood

bit.

Its stiffness

and

The

Expansive

is a

handy

t~ol

for

large

holes.

With

this

tool

you

can

drill a

variety

of

large

hole

sizes

without

having

to

buy

separate

large

diameter

drills

for

each

hole

size. As is

true

with

any

of

the

wood

bits

when

used

in

the

drill

press,

the

screw

point

must

be

filed

to

a

brad

point.

This

prevents

the

coarse

screw

threads

from

biting

into

the

work

and

lifting

it

from

the

table.

more

for

drill

use.

It

will

cut

cleaner

and

is less

apt

to

and

under

continuous

operation.

DRILL SHARPENING:

To

maintain

the

accuracy

and

cutting

efficiency

of

your

twist drills,

extreme

care

should

be

exercised

during

grinding.

The

two

cutting

lips

must

be

of

equal

length

and

their

angle

in

relation

to

the

axis

of

the

drill

must

be

equal.

Relieve

the

metal

gradually

behind

the

cutting

lips

so

that

the

angle

at

the

heel

of

the

cutting

edge

is

approximately

12

degrees

on

a

side

less

than

at

the

cutting

lip.

OPERATION:

Heel

Cutting

Lip

When

the

drill

press

is

used

for

wood

working

it

is

advisable

to

fasten

a

smooth

level

auxiliary

table

of

Y4

inch

p.lywood

to

the

metal

table

using

countersunk

flat

head

screws

or

bolts.

This

auxiliary

table

not

only

increases

the

working

surface

available,

but

pro-

vides

a

surface

on

which

auxiliary

fences,

shaping,

guides,

pivot

pins

and

other

similar

units

may

easily

be

used.

This

auxiliary

table

also

will

reduce

the

danger

of

drilling

through

the

work

piece

'into

the

metal

table.

If

the

drill is

to

pass

completely

through

the

work

piece

it is

advisable

to

place

a

piece

of

scrap

wood

under

the

work

piece

at

the

point

of

breaking

through

to

prevent

splintering

and

mutilation

of

the

lower

surface

as

the

bit

breaks

through.

Ano~her

method

of

preserving

the

surface,

at

drill

break

through

is

to

reverse

the

wood

and

drill

through

from

the

opposite

side

as

soon

as

the

drill

point

emerges

on

the

lower

'Surface.

Due

to

variation

in

the

bit

pattern,

the

type,

hard-

ness.

and

grain

of

the

material,

and

the

depth

and

quality

of

the

hole

desired,

it

is

impractical

to

at-

tempt

to

establish

a fixed

table

of

drill

feeds

and

speeds

for

boring

in

wood.

It

is

best

to

follow

this

general

rule:

the

larger

the

hole

and

the

harder

the

material

the

slower

the

feed

and

speed.

Start

any

drilling

operation

with

a

moderate

feed

and

speed,

increasing

either

or

both

after

noting

the

effect

on

the

drill.

In

wood

drilling

operations,

drills

up

to

¥.t

inch

in

diameter

may

generally

be

run

at

1800

to

3000

RP.M.

without

burning

while

bits

Y4

inch

in

diameter

and

over

cannot

generally

be

run

over

2400

RP.M.

without

burning.

Multi-spur

bits,

expansive

bits

and

hole

saws

should

never

be

operated

over

750

RP.M.

In

general,

if

the

drill

smokes

in

the

hole,

reduce

the

feed

and

speed

to

prevent

burning.

When

drilling

metal.

if

it

is

noted

that

the

drill

wears

away

at

the

extreme

outer

corners

of

the

cut-

ting

edges,

it

is

an

indication

of

too

much

speed.

Likewise

if

the

drill

chips

on

the

cutting

edge,

it

is

an

indication

of

too

heavy

a

feed.

Very

small

drills

are

generally

designed

for

high

speed

and

light

feed

and

should

be

used

accordingly

for

best

results.

A

straight

piece

clamped

to

the

table

as

a

guide

or

fence

has

many

uses,

as

in

drilling

several

holes

the

same

distance

from

a

common

edge

or

as

a

guide

in

grooving

or

fluting

operations.

The

work

piece

should

be

held

securely

on

the

table

either

by

clamps

or

pins

to

prevent

turning

with

the

drill.

A

drill

vise

is

an

inexpensive

and

very

handy

unit,

designed

to

hold

various

odd

shaped

work

pieces

for

drilling.

Cylindrical

work

pieces

such

as

dowels,

or

turned

work

pieces

of

various

diameters

present

dif-

ficulties

when

an

attempt

is

made

to

drill

through

or

into

their

centers

without

an

adequate

stabilizing

device.

The

drill

vise

or

a V

block

should

always

be

used

for

work

of

this

type.

If

the

drill

is

long

enough

to

go

through

the

piece.

but

its

'penetration

is

limited

by

the

travel

or

feed

limit

of

the

chuck.

the

piece

may

be

set

up

on

a

block

after

the

first

cut

of

maximum

feed

depth

has

been

made.

thus

allowing

the

drill

to

penetrate

to

its

max-

imum

length.

Holes

through

a'

piece.

the

thickness

of

which

is

greater

than

the

drill

length

may

often

be

completed

by

first

establishing

the

location

of

the

piece

in

rela-

tion

to

the

drill

center.

then

after

drilling

as

far

as

possible

from

one

side

the

piece

may

be

reversed

and

the

hole

completed

from

the

other

side.

All

metal

work

should

be

clamped

securely

to

the

work

table

before

drilling

is

attempted.

Should

the

drill

lodge

in

a

piece

not

clamped.

it

could

easily

tear

the

piece

from

the

operator's

grip

resulting

in

injury

to

the

operator

as

well

as

mutilation

of

the

drill

press

and

work

piece.

A

punch

mark

on

the

metal

surface

at

the

center

of

the

proposed

hole

will

tend

to

keep

the

drill

on

center

until

the

drill-spot

is

established.

Always

reduce

the

feed

pressure

when

the

drill

is

breaking

through

the

surface

of

a

work

piece.

This

reduces

the

tendency

of

the

drill

to

bite

deeply

at

this

point

and

thereby

minimizes

drill

breakage.

Avoid

set-ups

which

will

allow

the

work

to

spring.

This

will

help

minimize

drill

breakage.

Lubricants

should

be

used

on

all

metals

except

cast

iron

which

is

drilled

dry.

For

most

metals.

lard

oil is a

suitable

lubricant.

for

the

harder

metals

a

solution

of

sal

soda

in

water

may

be

used.

This

drill

press

is

designed

to

give
