  1. Step 1 Scegli il Dremel.
    The manufacturer produces different types of rotary tools.Do some research to understand which models are currently on sale and find the right one for your needs.Prices vary and it is therefore particularly important to find the right tool.Here are some:[1]
    • Fixed or corded bench tools;
    • Compact and portable tools or more robust and resistant;
    • Tools with long-lasting battery;
    • Fixed speed models (generally cheaper and easier to use) or variable speed models (more suitable for complex grinding projects, they are more expensive).
  2. Step 2 Leggi il manuale d'uso.
    The Dremel system is made up of a series of drill bits and other accessories, the body of the tool and is supplied with a user manual;Read it carefully before using the tool for the first time, so that you are familiar with the controls.Locate the knob that manages the speed, the on/off switch and the button for changing the tips.[2]
    • Since the model you own may be different from the previous year's, it is very important to read the instructions included with the tool you purchased.
  3. Step 3 Indossa i dispositivi di protezione.
    Always use work or rubber gloves when handling the Dremel;in this way, you avoid your hands coming into contact with material residues and sharp fragments.You should also use safety glasses, especially when cutting, polishing or grinding.[3]
    • Keep your work area clear;also prevent children and other people from getting close while you use the tool.
  4. Step 4 Fai delle prove inserendo e fissando le punte.
    To attach one, place it in the hole in the end of the tool and pull it out slightly.Tighten the housing latch to ensure the tip does not move.To remove it, press the shaft lock button while rotating the chuck;this way, you should free the tip to be able to replace it.[4]
    • Test by inserting and changing the bit while the tool is turned off and unplugged.
  5. Step 5 Usa l'accessorio corretto per il lavoro che devi svolgere.
    You should choose the tip based on the material you need to process.The Dremel company makes many bits out of numerous materials that can be used on almost any surface.For example:
    • Carving and engraving work:high-speed cutting bits, engraving bits, carbide cutters, tungsten carbide or diamond wheels;
    • Milling work:cutters (straight, angled, semicircular, grooved);
    • Small drilling jobs:drill bits (purchasable individually or in kits).
  6. Step 6 Verifica che l'utensile sia spento prima di inserire la spina nella presa di corrente.
    Once connected to power, set it to minimum speed and practice switching between the different speeds.
    • To get a "feel" for use, try holding the Dremel in different ways.For intricate work, you should hold it like a pencil, while for larger ones you should grip it firmly, wrapping it with all your fingers.
    • Use clamps or a vise to clamp the material you are working on.
  7. Step 7 Pulisci l'utensile dopo ogni utilizzo.
    Remove the tip and put it back in its container.Take the time to dust the body of your Dremel with a cloth after using it;by keeping it clean, it can last longer.Read the user manual before disassembling the tool for a more thorough cleaning.
    • You should often use compressed air to clean the vents on your Dremel to prevent electrical damage.

  1. Step 1 Usa il Dremel per eseguire dei piccoli tagli e incisioni di precisione.
    This tool is light and easy to handle;these characteristics make it ideal for creating details and making small cuts.Obtaining long, uniform curved lines is not easy, because almost all the work is done freehand.However, you may be able to make several straight incisions to get the profile you want and then sand it down with the appropriate bit.
    • Do not use the Dremel for long or large incisions, for which a large saw is more suitable.
  2. Step 2 Fissa l'oggetto.
    Depending on the item or material you need to cut, secure it with a vice or clamps;do not hold it with your hand.
  3. Step 3 Imposta la velocità di taglio appropriata in base alla punta e al materiale.
    If you choose one that is too high or too low, you can ruin the motor, the cutter or the material you are working on.If you have any doubts, consult the user manual to find out the specifications relating to the particular tool you have and the surface to be treated.
    • If you need to cut tough or thick material, pass the tip over the cutting line several times.
    • If you notice smoke or dark spots, it means you have chosen an excessive speed;If the motor makes sounds like it's slowing down or stalling, you're probably applying too much pressure;in this case, exert less force and adjust the speed.
  4. Step 4 Prova a tagliare la plastica.
    Insert a flat blade into the Dremel;Remember to wear eye and ear protection before starting work.Set a speed between 4 and 8 to have enough power, without running the risk of burning the engine;when finished, sand away the rough edges left by the cuts.[5] [6]
    • Do not press too hard while cutting, to avoid damaging the tool.
    • Depending on your project, it may be helpful to draw guidelines for cuts on the plastic;This way it's easier to practice them right where you want them.
  5. Step 5 Esercitati a tagliare il metallo.
    Secure the metal cutting wheel and wear ear and eye protection before proceeding.Turn on the Dremel, set the speed to between 8 and 10 and make sure the piece of metal is clamped securely in the vise.Gently rest the cutting wheel on the surface for a few seconds at a time until you feel the metal begin to cut.Expect sparks to form.[7] [8]
    • Fiberglass reinforced discs last longer than ceramic ones, which can chip when in contact with metal.

  1. Step 1 Mola usando il Dremel.
    Engage one abrasive grinder to the spindle/shaft.Slide it completely into the front hole of the instrument and tighten the latch.Run your Dremel on low speed to avoid overheating the material you are working on.Hold the grinding stone on the surface until it is as ground as you want.[9]
    • You can use abrasive grinders, discs, specific tips for chain saws and abrasive cutters;carbide ones are more effective on metal.
    • Use cylindrical or triangular tips to perform round work.To make an incision on a surface or sand the inside of a corner, use a flat disc;for round ones, choose a triangular or cylindrical tip.
  2. Step 2 Prova a levigare o affilare i materiali con il Dremel.
    Choose a tip with sandpaper and attach it to the tool.Tighten the screw at the end of the tip and start the tool, setting a speed between 2 and 10.Choose a low RPM if you're sanding or polishing plastic or wood surfaces.Opt for a higher speed for metal.Slide the tip over the material you want to smooth or sharpen after securing it in a vice;also make sure that the entire surface of the tip touches the object you are working on.[10]
    • Check that the tip is in good condition, to avoid leaving incisions or marks on the material.It should fit the drill securely and should not be worn.Keep several sanding bits on hand so you can quickly replace them.
    • For sanding you can use sanding strips, discs, abrasive detail brushes and finishing and shaping wheels.
  3. Step 3 Passa dalle punte più ruvide a quelle più lisce.
    If the project is not very large, start with the bits with the greatest abrasive power and then move on to the softer ones.This way you can get rid of large scratches quickly and have more control over the process.If you immediately use a soft tip, you may wear it out and take longer.[11]
    • Check the tip every minute or two for wear or tear.Remember to turn off and unplug your Dremel at each inspection.
  4. Step 4 Lucida il metallo o la plastica.
    Apply a polishing paste to the surface of the object and insert a cloth tip or disk into the tool.Turn on the drill at a low speed (2) and place the tip on the layer of polishing paste.You should move the tip in circular motions until the material is completely polished;do not set a high speed (do not exceed level 4).
    • You can also polish surfaces without using paste, although this will give you shinier results.
    • For polishing and cleaning work, use rubber tips or discs and abrasive brushes.These accessories are perfect for removing old paint from metal furniture or for cleaning tools and grills.

Advice

  • Check that every object you work on is securely attached.If it's a loose item, clamp it in a vice so it doesn't move.
  • Turn the tool on so that it is ready and spinning at full speed before it comes into contact with the material.
  • Remember not to apply excessive pressure when cutting or sanding;let the sandpaper or blade do all the work.
  • The tool comes with brushes that should last for 50 to 60 hours of use;If it doesn't seem to be working properly, have it checked by a technician.[12]
