USING THE “MORSE TAPER” SYSTEM DRILL BITS
(Fig.38)
This drill can accommodate larger drill bits than the chuck capacity. Industry uses
the morse taper system to fit drill bits. The morse taper system is a method of
securing an external (male) taper securely into an internal (female) tapered
adaptor. These tapers are referred to as self holding because they stay in place
when correctly seated. This system allows the easy changing of chucks and drill
bits. The internal and external tapers are ground at an angle that allows the two
tapers to lock together. This drill comes with a morse taper 2 chuck adaptor
(Fig.38c). Various accessories are available including chucks, drill bits, reamers
and adaptor sleeves with various size of “Morse Taper” shank. Fig.38 shows two
morse taper drill bits - 38a, a morse taper 3 adaptor - 38b, a morse taper 2
adaptor - 38c and a morse taper 2 chuck adaptor 38d.
There are two short vertical ejector slots machined in each side of the drive
spindle and the drive spindle housing that are accessible when the chuck is
lowered as in use (Fig.36). To remove the chuck from the morse taper, tap with
the soft mallet (Fig.35). To remove a morse taper drill bit, lower the drive spindle
and hold in position. Locate the ejector slot in the
drive spindle housing, then rotate the drive spindle
until the drive spindle ejector slots align with
ejector slots in the drive spindle housing (Fig.36).
Look at the side of the spindle and you will see
the tang in the ejector slots. To break the taper,
use the tapered drift key. Insert the drift key
(Fig.1) into the ejector slot above the tang with the
flat side uppermost
and using a soft
mallet tap the drift
until it breaks the
taper fit (Fig.37).
The chuck adaptor
or morse taper bit
will fall out of the
motor spindle.
When re-inserting,
offer up the new
bit or adaptor,
making sure you
feel the tang
locating in the slot
before tapping in
with the soft
mallet. (Fig.39 - 41)

LOCATING THE PILLAR DRILL
When determining where to locate or permanently fix the Pillar Drill,
consideration must be given to the following points.
Is there a suitable mains outlet socket near by. If the Pillar Drill is to be
permanently mounted onto a bench is the bench at a suitable height, strong
and stable enough to carry the weight of the Pillar Drill plus items to be
machined on it.
IDENTIFICATION/PREPARATION
Lift out the base plate, remove the protective paper and place the base on a
workbench or the floor.
Locate the chuck, chuck key, hexagonal keys. telescopic guard and drift key
and place to one side for time being.
Lift out the worktable, head stock/motor assembly and the column, remove
the protective paper and place them onto the workbench.
SECURING THE BASE PLATE
(Fig. 2)
Select a suitable location for the drill on the bench for mounting the base.
A suitable mains supply socket must also be accessible for the plug.
Locate the base plate in the selected position. Select four suitable length
fixing bolts, nuts and washers (not supplied).
Using the base plate as a template drill four holes in the bench with a suitable
drill bit. Insert the bolts, adding the nuts and washers underneath or above
depending on accessibility. Tighten the nuts onto the bolts to secure the base
onto the bench. Do not over tighten as this could crack the cast base.
FITTING THE COLUMN
(Fig. 3 & 4)
Lower the column into the cup on the top of the base (Fig.3) and use the
hexagon key supplied to tighten the three grub screws into the cup holding
the column (Fig.4). Do not over tighten as this could damage the column or
the cast cup.
