IntroductionThe Moto-Tool is a handful of high-speedpower. It serves as a carver, a grinder,polisher, sander, cutter, power brush, drill andmore.

The Moto-Tool has a small, powerful electricmotor, is comfortable in the hand, and ismade to accept a large variety of accessoriesincludingabrasive wheels, drillbits,wirebrushes,polishers, engraving cutters, router bits, andcutting wheels. Accessories come in a varietyof shapes and permit you to do a number of dIf-ferent jobs. As you become familiar with therange of accessories and their uses, you willlearn just how versatile the Moto-Toolis. You'llsee dozens of uses you hadn't thought of beforenow.

The real secret of the Moto-Toolis its speed. Tounderstand the advantages of its high speed,you have to know that the standard portableelectric drill runs at speeds up to 2,800 rev-

oJutlons per minute. The Moto- Tool operates atspeeds up to 30,000 revolutions per minute.The typical electric drill is a low-speed, high tor-que tool; the Moto- Tool Is just the opposite - ahigh-speed, low torque tool. The chief dif-ference to the user Is that in the high speedtools, the speed combined with the accessorymounted In the chuck does the work. You don'tapply pressure to the tool, but simply hold andguide it. In the low speed tools, you not onlyguide the tool, but also apply pressure to it, asyou do, for example, when drilling a hole.

It is this high speed, along with its compact sizeand wide variety of special accessories, thatmakes the Moto- Tooldifferent from other powertools. The speed enables it to do jobs low-speed tools cannot do, such as cutting har-dened steel, engraving glass, etc.

Getting the most out of your Moto- Tool Is a mat-ter of learning how to let this speed work foryou.

Operation GuidelinesRead the next sections carefully. They willhelp you use your Moto-Tool correctly andhelp you select the correct accessory foryour job.

Using the Moto- ToolThe first step in learning to use the Moto- Tool isto get the "feel" of it. Hold it in your hand andfeel its weight and balance. Feel the taper of thehousing. This taper permits the Moto- Tool to begrasped much like a pen or pencil.

When you turn on the tool for the first time, holdit away from your face. Accessories can bedamaged during handling, and can fly apart asthey come up to speed. This is not common,but it does happen.

Practice on scrap materials first to see how theMoto. Tool cuts. Keep in mind that the work isdone by the speed of the tool and by theaccessory in the chuck. You should not lean onor push the tool into the work.

Instead, lower the spinning accessory lightly tothe work and allow it to touch the point at whichyou want cutting (or sanding or etching, etc.) tobegin. Concentrate on guiding the tool over thework using very little pressure from your hand.Allow the accessory to do the work.

For best control In close work, grip theMota-Tool like a pencil between your thumband forefinger.

Usually, it is best to make a series of passes withthe tool rather than attempt to do all the work inone pass. To make a cut, for example, pass thetool back and forth over the work, much as youwould a small paint brush. Cut a little materialon each pass until you reach the desireddepth. For most work, the deft, gentle touch isbest. With it, you have the best control, are lesslikely to make errors, and will get the most effi-cient work out of the accessory.

~ When using the steel saws,~ cutoff wheels, high speedcutters or tungsten carbide cutters, alwayshave the work securely clamped. Neverattempt to hold the work with one handwhile using either of these accessories.The reason Is that these wheels will grab Ifthey become slightly canted In the groove,and can kickback causing loss of controlresulting In serious Injury. Your secondhand should be used to steady and guidethe hand holding the tool. When a cutoffwheel grabs, the wheel Itself usually breaks.When the steel saw, high speed cutters ortungsten carbide cutter grab, It may jumpfrom the groove and you could lose controlof the tool.

This Is the "handgrlp" method of holding thetool used for operations such as grinding aflat surface or using cutoff wheels.

~TO LOOSEN COLLET

COLLET - Consists of a collet nut and collet.To loosen, first press shaft Irick and rotate theshaft by hand until the lock engages the shaftpreventing further rotation.

~ Do not engage lock while~ the Moto-Toolls running.Withthe lock engaged use the collet wrench toloosen the collet nut. Change accessoriesinserting the new one into the collet as far aspossible to minimize runout and unbalance.With the lock engaged, tighten the collet nutwith the wrench until the accessory shank isgripped by the collet. Avoidexcessive tighten-ing of the collet nut. This means of securingaccessories is best when using the same bit forextended periods or during heavy materialremoval applications.

COLLETS - Four different size collets (seeillustration), to accommodate different shanksizes, are available for your Moto-Tool. Toinstall a different collet, remove the collet nutand remove the old collet. Insert the unslottedend of the collet in the hole in the end of the toolshaft. Replace collet nut on the shaft. Alwaysuse the collet which matches the shank size ofthe accessory you plan to use. Never force alarger diameter shank into a collet.

KEYLESS CHUCK - Remove collet and thekeyless chuck can be threaded on the end oftheshaft by engaging the shaft lock button. Youneed only use hand tightening to secure anaccessory. Use the keyless chuck when thereis a need to change bits frequently, for lightduty jobs.

BALANCING ACCESSORIES - Forprecisionwork, it is important that all accessories be ingood balance (much the same as the tires onyour automobile). To true up or balance anaccessory, slightly loosen collet nut and givethe accessory or collet a 1/4" turn. Retightencollet nut and run the Moto- Tool. You should beable to tell by the sound and feel if youraccessory is running in balance. Continueadjusting in this fashion until best balance isachieved. To maintain balance on abrasivewheel points, before each use, with the wheelpoint secured in the collet, turn on the Moto- Tooland run the 415 Dressing Stone lightly againstthe revolving wheel point. This removes highspots and trues up the wheel point for goodbalance.

WHEEL DIAMETER - Other than the No. 426cutoff wheel, do not use grinding wheelsover 1"ln diameter. Moto-TooI's high speedcan cause larger wheels to fly apart and couldcause injury.

SAFETY - Protect your eyes when grinding orrouting with the Moto-Tool... always wear anapproved type of safety glasses.

Remember, your new Dremel Moto- Tools thefinest power tool of its kind. But its pertor-

--mance is only as good as the accessories withwhich it is used. We recommend only Dremelaccessories be used. Use of any other acces-so~es may create a hazard. We hope you'llIl'"Joy many years of trouble free pleasure fromyour Dremel Moto-Tool.

Operating Speeds &AccessoriesSet the speed Indicator to fit the Job; toachieve the best Job results when workingwith different materials, the speed of theMoto. Tool should be regulated. Only a fullwave output speed control such as theDremel Models 219 and 221 should be usedwith the Model 275. Models 285 and 395Moto. Tool have an Integral speed controland an external speed control should neverbe used with these tools.

Toselect the right speed for each job, use apractice piece of material. Vary speed tofind the best speed for the accessory youare using and the job to be done.

There are three basic types of Moto- Tools:single speed, two-speed and variable speedmodels. On the single speed model, there is anON-OFF switch. When the switch is on, the toolruns at 28,000 RPM. On the two-speed model,there Is a LO and HI switch. When the switchindicator is on the low setting, the tool runs atabout 15,000 RPM. When the switch indicatoris on the high setting the tool runs about 28,000RPM. On the variable speed model, there is aswitch indicator with a white line on it. Slide tothe number on the housing to select the operat-ing speed needed from 5,000 - 30,000 R.P.M.You can refer to the charts on page 9 and 10 todetermine the proper speed, based on thematerial being worked and the type of cutter orother accessory being used. These charts enableyou to select both the correct accessory and theoptimum speed at a glance.

If you have a single speed or two-speed model,you wil be able to use many accessories to do awide assortment of jobs. For the majority ofapplications, all models of the Moto- Tool shouldbe used at top speed.

Needs for Slower SpeedsCertain materials, however, (some plastics, forexample) require a relatively slow speedbecause at high speed the friction of the toolgenerates heat and causes the plastic to melt.

Slow speeds (15,000 RPM or less) usually arebest for polishing operations employing the feltpolishing accessories. They may also be bestfor working on delicate projects as "eggery"work, delicate wood carving, and fragile model

parts. You should always do polishing withwire brush accessories at slower speeds andnever higher than 15,000 RPM.

higher speeds are better for carving, cutting,rOl,lting, shaping, cutting dadoes or rabbets.inwood. ..'

Hardwoods, metals, and glass require highspeed operation, and drilling should also bedone at high speeds.

The speed of Moto- Tool Is controlled by set.ting this Indicator on the housing.

If you need It, single-speed models also canhave speed control by the addition of a Model221 foot control unit.

The point to remember is this: You can do thegreat majority of work with the single speed at itsregular speed of 28,000 RPM. But for certainmaterials and types of work, you needslower speeds -which is the reason the variablespeed models and the speed control unitswere developed.

To aid you in determining the optimum opera-tional speed for different materials and differentaccessories, we have constructed a series oftables that appear on page 9 and 10. Byreferringto these tables, you can discoverthe recommendedspeeds for each type of accessory. Look thesetables over and become familiar with them.

Ultimately, the best way to determine the correctspeed for work on any material is to practice for afew minules on a piece of scrap, even after refer-ring to the chart. You can quickly leam that aslower or faster speed is more effective just byobserving what happens as you make a pass ortwo at different speeds. When working with plas-tic, for example, start at a slow rate of speedand increase the speed until you observe that theplastic is melting at the point of contact. Thenback the speed off slightly to get the optimumworking speed.

Some rules of thumb in regard to speed:1. Plastic and materials that melt at low tem-

peratures should be cut at low speeds.

2. Polishing, buffing and cleaning with a wirebrush should be done at speeds below 15,000RPM to prevent damage to the brush.

3. Soft wood should be cut at high speed.

4. Iron or steel should be cut at top speed ifusingtungsten carbide accessory, but at slowerspeeds if using high speed steel cutters. If ahigh speed steel cutter starts to chatter -thisnormallymeans it is running too slow.

5. Aluminum, copper alloys, lead alloys, zincalloys. and tin may be cut at any speed, depend-ing on the type of cutting being done. Useparaffinorother suitable lubricanton the cutterto prevent the cut materialfromadhering to thecutter teeth.

Increasing the pressure on the tool is not theanswer when it is not cutting as you think itshould. Perhaps you should be using a differentcutter, and perhaps an adjustment in speedwould solve the problem. But leaning on the toolseldom helps.

Moto. Tool Accessories

The number and variety of accessories for theMoto- Tool are almost limitless. There is a cate-gory suited to almost any job you might have todo-and a variety of sizes and shapes withineach category which enables you to get the per-fect accessory for every need.

Refer to the DREMEL BITS OF INFORMATIONACCESSORY ORDER FORM for illustrationsof the accessories available. These access-ories may be found at your local hardware,hobby or home center dealers.

c=:J!)ColletsIf you expect to use a variety of accessories, werecommend that in the beginning you purchasea complete set of four collets. Store these sothat you will have the proper size of collet for anyaccessory or drill bit you want to use. Currently,the 1/8- and 3/32- collets accommodate allof the available Dremel accessories.

MandrelsA mandrel is a shank with a threaded or screwhead, and mandrels are required when you usepolishing accessories, cutting wheels, sandingdiscs, and polishing points. The reason man-drels are used is that sanding discs, cuttingheels and similar accessories must be replacedfrequently. The mandrel is a permanent shank,allowing you to replace only the worn headwhen necessary, thus saving the expense ofreplacing the shaft each time.

,~Screw Mandrel No. 401This is a screw mandrel used with the felt polish.ing tip and felt polishing wheels

, 0Smatl Screw Mandrel No. 402This Is a mandrel with a small screw at Its tip,and is used with emery cutting wheels, sandingdiscs, and polishing wheels.

~Threaded Tip Mandrel No. 424This is a mandrel with threaded tip which threadsinto the polishing point accessory No. 421.

High Speed 'cutters ~Available in many shapes, high speed cuttersare used In carving, cutting, and slotting inwood, plastics, and soft metals such as alu-minum, copper, and brass. These are theaccessories to use for freehand routing or carvingin wood or plastic, and for precision cutting.

r I --Tungsten Carbide CuttersThese are tough, long-lived cutters for use onhardened steel, fired ceramics, and other veryhard materials. They can be used for engravingon tools and garden equipment.

r I .Small Engraving CuttersThis group nas a Wide variety of sizes andshapes, and are made for intricate work onceramics (greenware), wood carvings, jewelry,and scrimshaw. They often are used in makingcomplicated printed circuit boards. Theyshould not be used on steel and other very hardmaterials but are excellent on wood, plastic,and soft metals. Needs 3/32" collet.

tl~tiTStructured Tooth

Tungsten Carbide CuttersFast cutting, needle-sharp teeth for greatermaterial removal, minimum loading. Use onfiberglass, wood, plastic, epoxy and rubber.

~Aluminum Oxide Grinding StonesRound, pointed, flat- you name the shape andthere is one available In this category. Theseare made of aluminum oxide and cover virtuallyevery possible kind of grinding application.Use them for sharpening lawn mowers blades,screwdriver tips, knives, scissors, chisels andother cutting tools. Use to .remove flash frommetal castings, deburring any metal after cut-ting, smoothing welded joints, grinding offrivets and removing rust. In machine shops,high speed drills and cutters normally areground with aluminum oxide wheels.

r I .::C:>

Silicon Carbide Grlndln~ StonesTougher than aluminum oxide points, these aremade especially for use on hard materials suchas glass and ceramics. Typical uses might bethe removal of stilt marks and excess glaze onceramics and engraving on glass.

Neverattempt to hold the work with one handwhile using either of these accessories.The reason Is that these wheels will grab Ifthey become slightly canted In the groove,and can kickback causing loss of controlresulting In serious Injury. Your secondhand should be used to steady and guidethe hand holding the tool. When a cutoffwheel grabs, the wheel Itself usually breaks.When the steel saws, high speed cutter ortungsten carbide cutter grab, It may jumpfrom the groove and you could lose controlof the tool.

BRUSH )'Y?:iJSPRING rCURVATURE BRUSHOF HOUSING CAP

With the cord unplugged, remove the brushcaps one at a time with a small screwdriver byrotating cap counter-clockwise and check eachbrush.

If the brush is less than 1/8" long and the endsurface of the brush that contacts the com-mutator is rough and/or pitted, they should bereplaced. Check both brushes. Usually thebrushes will not wear out simultaneously. If onebrush is worn out, replace both brushes. Make

sure the brushes are inslalled as illustrated.The curved surface of the brush must match thecurvature of the commutator.

After replacing brushes the tool should be run atno-load; place it on a clean surface and run itfreely for 5 minutes before loading (or using) thetool. This will allow the brushes to "seat" pro.perly and will give you more hours of life fromeach set of brushes. This will also extend thetotal life of your tool since the commutator sur-face will "wear" longer.
