• 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.

Drilling or other use of this tool may produce hazardous fumesand/or dust. To avoid adverse health effects utilize adequateventilation and/or a respirator. Read the material safety datasheet of any cutting fluids or materials involved in the drillingprocess.

Some non-ferrous metal chips (or dusts) are combustible. Ex-amples: Aluminum, magnesium, Titanium, and Zirconium. Seethe material safety data sheets for combustibility of materialsdrilled. Never collect spark generating material with combustiblematerial. Examples: Collecting both steel and aluminum or steeland titanium.

Quackenbush drills are often used with lubricant or coolingsystems which must be properly maintained to avoid leakage.Failure to do so can result in serious injuries from slipping on oilysurfaces.

For your safety and the safety of others, read and understandthe safety recommendations and operating instructions be-fore operating any drill motor.

Always wear protective equipment:

For additional information on eye protection, read the latest editionof ANSI Z87.1, Occupational and Educational Eye and FaceProtection. This standard is available from the American NationalStandards Institute, Inc., 11 West 42nd Street, New York, N.Y.10036.

Hearing protection is recommended in high noise areas (above85dBA). Close proximity of additional tools, reflective surfaces,process noises, etc., can contribute substantially to the soundlevel experienced by the operator.

Follow good machine shop practices. Rotating shafts and movingcomponents entangle and entrap, and may result in seriousinjuries. 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 airpressure increases the loads and stresses on tool parts and drills,and may result in breakage. The installation of a filter-regulator-lubricator in the air supply line ahead of the tool is highly recom-mended.

Due to the number and variety of tooling applications, the user'smethods engineering departments, ect., must consider any haz-ards that may be associated with each specific application of thisproduct and provide adequate operator protection from inadvert-ent contact with any moving components. The clamping and feedmechanisms of self-colleting drill motors are exposed for visibilityand can move when the air supply is connected or disconnected.To avoid injury, keep fingers and hands away from these areaswhen handling or operating this tool.

Some individuals are susceptible to disorders of the hands andarms when exposed to vibration and/or tasks which involverepetitive work motions. Those individuals predisposed to vascu-latory or circulatory problems may be particularly susceptible.Cumulative trauma disorders such as carpal tunnel syndrome andtendinitis can be caused or aggravated by repetitious, forcefulexertions of the hands and arms. These disorders develop gradu-ally over periods of weeks, months, and years. Tasks should beperformed in such a manner that the wrists are maintained in aneutral position, which is not flexed, hyperextended, or turned sideto side. Stressful postures should be avoided and can be con-trolled through tool selection and work location.


Any tool operator should be aware of the following warning signsand symptoms so that a problem can be addressed before itbecomes a debilitating injury. Any user suffering from prolongedsymptoms of tingling, numbness, blanching of fingers, clumsi-ness or weakened grip, inability to hold objects, nocturnal pain inthe hand, or any other disorder of the shoulders, arms, wrists, orfingers should notify their employer so that a review of what stepsmight be taken to prevent further occurances. These steps mightinclude but are not limited to, repositioning the workpiece orredesigning the workstation, reassigning tool users to other jobs,rotating jobs, changing worker pace, and/or changing the type oftool used so as to minimize stress on the operator. Some tasksmay require more than one type of tool to obtain the optimumoperator/ tool/ task relationship.

The following recommendations will help reduce or moderate theeffects of repetitive work motions. The operator of any drill should:

• Use a minimum hand grip force consistent with proper control and safe operation

• Keep body and hands warm and dry• Avoid anything that inhibits blood circulation

— Smoking Tobacco— Cold Temperatures— Certain Drugs

• Avoid awkward postures• Keep wrists as straight as possible• Interrupt work, activities, or rotate jobs to provide

periods free from repetitive work motions.

WARNING!

Repetitive work motions can injure your hands and arms.

The Q-Matic 120SC-225 are air operated, hydraulicallycontrolled tool that automatically clamps to the material,drills and countersinks close tolerance holes in one opera-tion. The Q-Matic will produce high quality holes in alumi-num, steel, titanium and petroleum hybrid materials prima-rily found in the aircraft/aerospace industries. The Q-Maticself-colleting drill motor has been designed using state-of-the-art technology that provides maximum power,minimumweight and the highest degree of accuracy for demandinghole preparation requirements.

Technical DataFeed Stroke: Feed stroke of the Q-Matic 120SC-225 is 2.25inches to drill and countersink in 2 inch stacked material. Thefeed stroke is unaffected by the collet stroke.Collet Stroke: The Q-Matic 120SC-225 will clamp through-out its .875 inch stroke. Collet stroke is unaffected by feedstroke.Spindle Adjustment: The spindle adjustment of .375 inchallows for drill length variations. See Spindle Adjustmentinformation on page 25.Countersink Depth Control: A micrometer adjustmentprovides for countersink stop repeatability within .001 inch.Cutter Sizes: The Q-Matic 120SC-225 will accommodate.500 diameter drills without countersink and.781 counter-sink diameter.Feed Rate: An adjustable drill feed rate mechanism enablesthe Q-Matic 120SC-225 to drill from 5 seconds per inch to 1minute per inch. See Feed Rate Adjustment information onpage 25.Cutter to Collet Spacing: The cutter to collet distance isadjustable between 1.00 inch minimum to 3.50 inch maxi-mum.Coolant: The Q-Matic 120SC-225 has a drill point coolantport 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 1.2horsepower nominal when supplied with air at 90 p.s.i.

Air Consumption: Air consumption of the Q-Matic 120SC-225 is 45 c.f.m. at 90 p.s.i. dynamic.Weight: 15SC-225 weight with the aluminum pressure footis 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 30thru 31 for gear set assembly configurations. Any gear setcan be used with the 120SC-225 tool. See pages 31 thru 32for gear set assembly configurations.Trigger Lock: A trigger lock is provided which allows the toolto be locked in the "Operate" position. With the lock acti-vated, the tool will run through the clamp, feed and retractcycles, but it will not unclamp or stop the motor until thetrigger lock is manually released.

Tool Start-UpThe Q-Matic 120SC-225 drill is shipped from the factoryequipped to the customer's specifications: spindle RPM,spindle to accommodate cutter type desired, pressure foottype, collet guide to accommodate collet desired and op-tional booster pump (if required).After unpacking, examine the customer-specified equip-ment on the Q-Matic tool to verify type and speed ofcomponents. Attach air line to 3/8-18 NPT inlet bushing. Ifquick disconnect fittings are used, 3/8 in. ID are minimum.The Q-Matic 120SC-225 drill requires a supply of clean 90-100 PSI air. Air consumption is 45 CFM at 90 PSI. The useof the in-line lubricator will provide the proper lubrication forthe air motor and will significantly increase the tool lifeexpectancy.Because O-rings are extensively used to seal systemswithin the tool, the elimination of foreign particles and othercontaminants will reduce the possibility of damage to theseparts. Always inspect O-rings for damage or wear andreplace as required. The use of silicone O-ring lubricant isstrongly recommended during reassembly. The addition ofoil in the air line will also increase motor and valve life as wellas the life of the O-rings. Avoid the use of synthetic lubricantsto 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 AdjustmentLoosen spindle adjustment lock, then turn spindle adjust-ment knob. Right hand rotation advances cutter foward;left hand rotation returns cutter. Correct cutter pointposition is flush with face of template boss. When cutteris properly adjusted, lightly tighten spindle adjustmentlock to hold adjustment.

Micrometer Depth AdjustmentLoosen adjustment clamp, and rotate depth adjustmentnut. Clockwise rotation decreases depth; counterclock-wise increases depth. Graduations scribed on barrel arein .001" increments. When proper depth is achieved.lightly tighten adjustment clamp.

Feed Rate AdjustmentWith appropriate tool, turning feed rate adjustment coun-terclockwise, increase feed rate. Turning the screw clock-wise decreases feed rate. Feed rate can be measured byusing the following formula:

60 secondsTime to drill one inch = ------------------------------------------

Feed Rate x Spindle Speed (rpm)

Dwell AdjustmentInsert appropriate size allen wrench into dwell adjustmentvalve opening. Rotate wrench clockwise until valve seatslightly. Rotate valve counterclockwise 1/2 turn to obtainbase setting.Note: If adjustment valve is opened too far, drill motor willnot cycle, and feed cycle cannot be obtained. To correct,turn valve clockwise to seat valve and set according toinstructions above.

If valve is closed too far, retract cycle cannot be obtained.To correct, turn valve counterclockwise and set accord-ing to instructions.

Closing valve increases countersink dwell time; openingvalve decreases countersink dwell time.

Tail Pad AdjustmentThe purpose of the tail pad is to compensate for slghtsurface curvature of the workpiece being drilling and toassure that the hole being drilled is perpendicular to thesurface.

To adjust to a flat plane for drilling flat surfaces, use astraight edge between the tail pad and face of templateboss and adjust the tail pad until the straight edge is flushwith the face of the template boss.

An optional tail pad is available for high curvature sur-faces. ( See Accessories for more information.)
