Safety Recommendations
For your safety and the safety of others, read and understand
the safety recommendations and operating instructions before operating any drill motor.
Always wear protective equipment:
WARNING!
Impact resistant eye protection
must be worn while operating
or working near this tool.
For additional information on eye protection, read the latest edition
of ANSI Z87.1, Occupational and Educational Eye and Face
Protection. This standard is available from the American National
Standards Institute, Inc., 11 West 42nd Street, New York, N.Y.
10036.
CAUTION!
Personal hearing protection is
recommended when operating
or working near this tool.
Hearing protection is recommended in high noise areas (above
85dBA). Close proximity of additional tools, reflective surfaces,
process noises, etc., can contribute substantially to the sound
level experienced by the operator.
WARNING
!
CAUTION!
• Before the tool is connected to the air supply, the throttle should
be checked for proper operation (i.e., throttle valve moves freely
and returns to closed position).
• Before removing a tool from service or changing drill bits, make
sure the air line is shut off and drained of air. This will prevent the
tool from operating if the throttle is accidently engaged.
• Cutting tools used with these drill motors are sharp. Handle them
carefully to avoid injury.
• The collet and mandrel must be inserted into a properly sized
pre-drilled hole before starting the tool. An improperly sized pre drilled hole prevents the mandrel from engaging the collet and
could result in slippage of the tool. An improperly selected collet
and mandrel can also result in slippage of the tool.
!
WARNING
Wear respirator where
necessary.
Drilling or other use of this tool may produce hazardous fumes
and/or dust. To avoid adverse health effects utilize adequate
ventilation and/or a respirator. Read the material safety data
sheet of any cutting fluids or materials involved in the drilling
process.
Do not wear loose fitting clothes,
long hair, gloves, ties or jewelry.
Follow good machine shop practices. Rotating shafts and moving
components entangle and entrap, and may result in serious
injuries. Never wear long hair, loose-fitting clothes, gloves, ties,
or jewelry when working with or near a drill of any type.
Quackenbush drills are designed to operate on 90psig (6.2 bar)
maximum air pressure using the proper hose. Excessive air
pressure increases the loads and stresses on tool parts and drills,
and may result in breakage. The installation of a filter-regulatorlubricator in the air supply line ahead of the tool is highly recommended.
CAUTION
!
Some non-ferrous metal chips (or dusts) are combustible. Examples: Aluminum, magnesium, Titanium, and Zirconium. See
the material safety data sheets for combustibility of materials
drilled. Never collect spark generating material with combustible
material. Examples: Collecting both steel and aluminum or steel
and titanium.
CAUTION!
Slip and fall hazard.
Lubricant and coolant systems must
be properly maintained to avoid
leakage.
Hoses must be organized and care
taken to avoid tripping.
Quackenbush drills are often used with lubricant or cooling
systems which must be properly maintained to avoid leakage.
Failure to do so can result in serious injuries from slipping on oily
surfaces.

Some individuals are susceptible to disorders of the hands and
arms when exposed to vibration and/or tasks which involve
repetitive work motions. Those individuals predisposed to vasculatory or circulatory problems may be particularly susceptible.
Cumulative trauma disorders such as carpal tunnel syndrome and
tendinitis can be caused or aggravated by repetitious, forceful
exertions of the hands and arms. These disorders develop gradually over periods of weeks, months, and years. Tasks should be
performed in such a manner that the wrists are maintained in a
neutral position, which is not flexed, hyperextended, or turned side
to side. Stressful postures should be avoided and can be controlled through tool selection and work location.
Any tool operator should be aware of the following warning signs
and symptoms so that a problem can be addressed before it
becomes a debilitating injury. Any user suffering from prolonged
symptoms of tingling, numbness, blanching of fingers, clumsiness or weakened grip, inability to hold objects, nocturnal pain in
the hand, or any other disorder of the shoulders, arms, wrists, or
fingers should notify their employer so that a review of what steps
might be taken to prevent further occurances. These steps might
include but are not limited to, repositioning the workpiece or
redesigning the workstation, reassigning tool users to other jobs,
rotating jobs, changing worker pace, and/or changing the type of
tool used so as to minimize stress on the operator. Some tasks
may require more than one type of tool to obtain the optimum
operator/ tool/ task relationship.

Introduction and General Information
The Q-Matic 120SC-225 are air operated, hydraulically
controlled tool that automatically clamps to the material,
drills and countersinks close tolerance holes in one operation. The Q-Matic will produce high quality holes in aluminum, steel, titanium and petroleum hybrid materials primarily found in the aircraft/aerospace industries. The Q-Matic
self-colleting drill motor has been designed using state-ofthe-art technology that provides maximum power,minimum
weight and the highest degree of accuracy for demanding
hole preparation requirements.
Technical Data
Feed Stroke: Feed stroke of the Q-Matic 120SC-225 is 2.25
inches to drill and countersink in 2 inch stacked material. The
feed stroke is unaffected by the collet stroke.
Collet Stroke: The Q-Matic 120SC-225 will clamp throughout its .875 inch stroke. Collet stroke is unaffected by feed
stroke.
Spindle Adjustment: The spindle adjustment of .375 inch
allows for drill length variations. See Spindle Adjustment
information on page 25.
Countersink Depth Control: A micrometer adjustment
provides for countersink stop repeatability within .001 inch.
Cutter Sizes: The Q-Matic 120SC-225 will accommodate
.500 diameter drills without countersink and.781 countersink diameter.
Feed Rate: An adjustable drill feed rate mechanism enables
the Q-Matic 120SC-225 to drill from 5 seconds per inch to 1
minute per inch. See Feed Rate Adjustment information on
page 25.
Cutter to Collet Spacing: The cutter to collet distance is
adjustable between 1.00 inch minimum to 3.50 inch maximum.
Coolant: The Q-Matic 120SC-225 has a drill point coolant
port in the pressure foot. A coolant mist lubricator is available
(See Accessories Page 33-34)
Air Motor: The air motor for the 120SC-225 is rated at 1.2
horsepower nominal when supplied with air at 90 p.s.i.
Air Consumption: Air consumption of the Q-Matic 120SC225 is 45 c.f.m. at 90 p.s.i. dynamic.
Weight: 15SC-225 weight with the aluminum pressure foot
is 13 pounds.
Spindle Speeds: Eleven geared spindle speeds are avail-
able with the 120SC-225: 270, 470, 700, 900, 1,150, 2,200,
3,500, 5,500, 7,000, 14,000, 23,5000 RPM. See pages 30
thru 31 for gear set assembly configurations. Any gear set
can be used with the 120SC-225 tool. See pages 31 thru 32
for gear set assembly configurations.
Trigger Lock: A trigger lock is provided which allows the tool
to be locked in the "Operate" position. With the lock activated, the tool will run through the clamp, feed and retract
cycles, but it will not unclamp or stop the motor until the
trigger lock is manually released.
Tool Start-Up
The Q-Matic 120SC-225 drill is shipped from the factory
equipped to the customer's specifications: spindle RPM,
spindle to accommodate cutter type desired, pressure foot
type, collet guide to accommodate collet desired and optional booster pump (if required).
After unpacking, examine the customer-specified equipment on the Q-Matic tool to verify type and speed of
components. Attach air line to 3/8-18 NPT inlet bushing. If
quick disconnect fittings are used, 3/8 in. ID are minimum.
The Q-Matic 120SC-225 drill requires a supply of clean 90100 PSI air. Air consumption is 45 CFM at 90 PSI. The use
of the in-line lubricator will provide the proper lubrication for
the air motor and will significantly increase the tool life
expectancy.
Because O-rings are extensively used to seal systems
within the tool, the elimination of foreign particles and other
contaminants will reduce the possibility of damage to these
parts. Always inspect O-rings for damage or wear and
replace as required. The use of silicone O-ring lubricant is
strongly recommended during reassembly. The addition of
oil in the air line will also increase motor and valve life as well
as the life of the O-rings. Avoid the use of synthetic lubricants
to prevent damage to O-rings and seals.

Tool Adjustments
WARNING: Disconnect air-supply before servicing.
Clamp mechanism moves when connecting or removing air supply.
Keep hands and fingers away from clamping and feed mechanism.
Spindle Stroke Adjustment
Loosen spindle adjustment lock, then turn spindle adjustment knob. Right hand rotation advances cutter foward;
left hand rotation returns cutter. Correct cutter point
position is flush with face of template boss. When cutter
is properly adjusted, lightly tighten spindle adjustment
lock to hold adjustment.
Micrometer Depth Adjustment
Loosen adjustment clamp, and rotate depth adjustment
nut. Clockwise rotation decreases depth; counterclockwise increases depth. Graduations scribed on barrel are
in .001" increments. When proper depth is achieved.
lightly tighten adjustment clamp.
Feed Rate Adjustment
With appropriate tool, turning feed rate adjustment counterclockwise, increase feed rate. Turning the screw clockwise decreases feed rate. Feed rate can be measured by
using the following formula:
60 seconds
Time to drill one inch = ------------------------------------------
Feed Rate x Spindle Speed (rpm)
Dwell Adjustment
Insert appropriate size allen wrench into dwell adjustment
valve opening. Rotate wrench clockwise until valve seats
lightly. Rotate valve counterclockwise 1/2 turn to obtain
base setting.
Note: If adjustment valve is opened too far, drill motor will
not cycle, and feed cycle cannot be obtained. To correct,
turn valve clockwise to seat valve and set according to
instructions above.
If valve is closed too far, retract cycle cannot be obtained.
To correct, turn valve counterclockwise and set according to instructions.
Closing valve increases countersink dwell time; opening
valve decreases countersink dwell time.
Tail Pad Adjustment
The purpose of the tail pad is to compensate for slght
surface curvature of the workpiece being drilling and to
assure that the hole being drilled is perpendicular to the
surface.
To adjust to a flat plane for drilling flat surfaces, use a
straight edge between the tail pad and face of template
boss and adjust the tail pad until the straight edge is flush
with the face of the template boss.
An optional tail pad is available for high curvature surfaces. ( See Accessories for more information.)
