SHARPENING THE DRILL BIT & CHISEL
SAFETY PRECAUTIONS
GENERAL SAFETY RULES FOR OPERATING MACHINERY
For best performance the chisel and bit need to be kept sharp. Blunt cutting
edges will give untidy and inaccurate mortises, and can cause overheating
and breaking of the chisel and bit.
Sharpen the bit by using a small smooth
file, following the original shape of the
bit. File the inside edge of the spur, the
sides of the brad point, and the cutting
edge inwards towards the flutes of the
bit to restore sharpness. Do not file the
outside edge of the spur as this will
affect the diameter of the bit.
WARNING:
As with all machinery, there are certain hazards involved with their operation and
use. Exercising respect and caution will considerably lessen the risk of personal
injury. However, if normal safety precautions are overlooked or ignored, personal
injury to the operator or damage to property, may result.
1.
READ and BECOME FAMILIAR with the entire operating manual. Learn the
machines’ applications and limitations as well as the specific potential hazards
peculiar to it.
2.
EARTH ALL MACHINES. If the machine is equipped with three-pin plug, it should
be plugged into a three-pin electrical socket. Never remove the earth pin.
3.
ALWAYS ensure that ADEQUATE LIGHTING is available. A minimum intensity of
300 lux should be provided. Ensure that lighting is placed so that you will not
be working in your own shadow.
4.
CHECK for DAMAGE. Before using the machine, any damaged part, such as
a guard etc., should be checked to ensure that it will operate properly, and
perform its intended function. Check for alignment of moving parts, breakage
of parts, mountings, and any other condition that may affect the machines’
operation. Any damage should be properly repaired or the part replaced. If
in doubt, DO NOT USE the machine. Consult your local dealer.
5. DISCONNECT the MACHINE from the power supply before servicing and when
changing accessories or performing maintenance tasks.
Use a Mortise chisel cutter with the correct size
pilot to sharpen the chisel. Two or three turns of
the cutter in a carpenters hand brace should be
enough to sharpen the chisel. Remove any burrs
from the outside of the chisel with a fine oilstone.
Chisels and bits will need replacing when they
become badly worn and difficult to sharpen.
6. KEEP GUARDS in place and in working order.
7. ALWAYS WEAR SAFETY GOGGLES, manufactured to the latest European Safety
Standards. Also use face or dust mask if cutting operation is dusty. Everyday
eyeglasses do not have impact resistant lenses, they are NOT safety glasses.
8. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
9. DON’T FORCE the Machine. It will do a better and safer job at the rate for
which it was designed.
10. REMOVE ADJUSTING KEYS AND WRENCHES. Form the habit of checking to see that
keys and adjusting wrenches are removed from the machine before switching on.
11. DRUGS, ALCOHOL, MEDICATION. Do not operate machine whilst under the
influence of drugs, alcohol or any medication.
12. USE RECOMMENDED ACCESSORIES. The use of improper accessories could
be hazardous.
13. NEVER LEAVE MACHINE RUNNING UNATTENDED. Turn power OFF. Do not leave
machine until it comes to a complete stop.
10
3
14. KEEP CHILDREN AWAY. All visitors should be kept a safe distance from the work
area, especially whilst operating the unit.
15. MAINTAIN MACHINE IN TOP CONDITION. Keep tools sharp and clean for the
best and safest performance. Follow maintenance instructions.
7
16. DON’T OVERREACH. Keep your proper footing and balance at all times. For best
footing, wear rubber soled footwear. Keep floor clear of oil, scrap wood, etc.
Observing all precautions (refer to your drill press manual), and ensuring there are
no obstructions, or tools in the vicinity, plug into the mains supply and switch ON.
Gently lower the chisel so that it contacts the work, and, ensuring it is properly
positioned, proceed to force the chisel into the work.
17. WEAR PROPER APPAREL. Loose clothing or jewellery may get caught in moving
parts. Wear protective hair covering to contain long hair.
If your drill press is provided with a depth stop, it may be used to limit the depth of
the chisel cut. Refer to your drill press manual for the method of adjustment.
18. BE AWARE that accidents are caused by carelessness due to familiarity. ALWAYS
concentrate on the job in hand, no matter how trivial it may seem.
ADDITIONAL SAFETY INSTRUCTIONS when MORTISING
NOTES:
• It is recommended that you check the position, and depth of cut, on a piece
of scrap of similar size before cutting your workpiece.
•
The rate of penetration of the chisel must be fast enough to prevent burning at the
tip of the bit, but not so fast as to cause the machine to slow or stall. With experience
you will find suitable feed rates to suit various types of timber.
•
You may encounter smoke from the bit or material once the chisel has engaged
the material. The smoke created is a natural operating occurrence in hollow chisel
mortising and is caused by material chip friction and the resins in the stock being
burned off. Bluing of the chisel after initial use is not indicative of a dull chisel, but a
combination of friction and resin buildup on the cutting faces of the chisel.
•
A dull chisel can be detected by the amount of excess force required to
complete a cut.
•
After the first cut, the workpiece must be moved along in the correct direction
relative to the slot in the chisel, to allow chips to clear freely. Move the workpiece
so that the chisel slot is releasing chips into the already cut part of the mortise.
•
Do not have the slot against the blind end of the mortise, as the chips will
not be able to clear from the chisel. This will cause overheating and possible
breakage to the chisel or bit.
11. NEVER START the machine with the drill bit or chisel pressed against the
workpiece.
•
When cutting deep mortises, make the cut in several stages of no more than 25mm
each, to allow chips to clear.
12. NEVER PERFORM LAYOUT, assembly or setup work on the machine with the
cutting tool rotating.
•
Always switch the mortising machine off after use. Never leave the machine
running unattended.
13. ALWAYS ADJUST DEPTH STOP wherever possible, to avoid drilling into the table.
•
If the Morticing attachment is left on the drill press, ensure the plastic protection
cap (provided), is placed over the end of the chisel to avoid the possibility of
people damaging themselves on the sharp points subsequently.
1. DO NOT USE until unit is completely assembled and installed according to
these instructions.
2. IF YOU ARE NOT thoroughly familiar with the mortising operations, you should
obtain advice from a qualified person.
4. NEVER TURN MACHINE ON before clearing the table of all objects (tools, scrap
pieces, etc.).
5. ALWAYS KEEP hands, fingers and hair well away from the rotating bit.
6. DO NOT ATTEMPT to mortise materials that do not have a flat surface.
7. ALWAYS use the ‘Hold Down’ to prevent work from lifting when withdrawing
the chisel.
8. ALWAYS SUPPORT workpiece securely against fence to prevent rotation.
9. ENSURE chisel and bit is sharp, undamaged and properly secured before use.
10. ENSURE the chuck key is removed before starting.
14. ALWAYS STOP the machine before removing scrap pieces from the table.
15. SHUT OFF POWER, remove the drill bit and chisel and clean the table before
leaving the machine.
16. NEVER PLACE YOUR FINGERS in a position where the drill or cutting tool could
contact them if the workpiece should shift unexpectedly.

UNPACKING
Unpack the shipping carton, and lay out the components so that they can be
clearly identified. Check them off as follows:
DO NOT force the
workpiece, it should be
firm, but allowed to move
laterally, by hand.
•
Lower the Hold Down so
that it makes contact
with the workpiece.
Again DO NOT force the
hold down - the
workpiece should be
allowed to move laterally
by hand.
6
Lower the chisel and bit, (or raise
the table) so it is directly above the
proposed Mortise.
NOTE:
If your table is capable of rotating
about the column, ensure it is
secured with the hole in the table
directly beneath the chisel.
If you have a round table with
radial slots, which rotates about its
axis, you need to lock the table in
a position where the assembly can
be manoeuvred, in the radial slots,
so that the proposed Mortise lies
directly beneath the chisel.
Should there be any deficiency or damage to any of the components, please
contact your Clarke dealer immediately
You should always mark your
Mortise on the workpiece clearly,
beforehand.
The chisel must be square with the workpiece, as shown. Move the complete
assembly on the table until you are satisfied it is, then clamp the complete assembly
to the table using the wing nuts on the hold down support securing bolts.
Your Morticing Attachment is now set up and ready for use.

IMPORTANT!
A clearance of 1/16” (1.5mm) MUST exist between the
mating faces of ther chisel and bit, as shown in Fig. 2A.
If the bit bottoms out in the chuck before it makes
contact with the chisel, either grind off the end of the
bit (shank), or, slacken the screw securing the chisel
holder and lower the holder sufficiently so that a
coorrect clearance may be set.
It should also be noted that it may be necessary to
increase the size of the gap with hardwoods, or when
cutting deep mortices.
Mount the Chisel Holder on the
collar surrounding the drill press
spindle, as shown.
Attach the Fence and the Hold Down
Support to the table in the manner shown.
Do not fully tighten the wing nuts at this
stage
3
It may be necessary to use a
collar insert in order for the
holder to fit correctly. Three
such collars are provided.
Note that the securing bolts (A) are extra
long. This is to allow a piece of timber to
be placed beneath the fence, which
may be used as a bed, on which to place
the workpiece. This is used when through
mortices are to be cut, and will avoid
splintering of the workpiece and possible
damage to the chisel and bit on
breakthrough (Depending upon the type
of table being used).
Such a setup is shown in ‘4’ below.
Tighten the pinch bolt ‘A’.
2
Install the chisel and bit as follows:
WARNING!
Take great care when handling the
chisel and bit...the edges are
extremely sharp.
Use the plastic protection cap
(provided), whenever possible
•
Separate the chisel and bit, then Insert the
chisel up through the hole in the Chisel Holder.
•
Push the chisel up as far as possible into the
holder, and nip up the securing screw to
temporarily hold it in this position.
NOTE:
The opening in the side of the chisel should always be
to the right or left, never to the front or rear. The opening
allows chips to escape during operation. See ‘Adjusting
Chisel Parallel to Workpiece’ on page 10.
