From Home & Local Store - Plastic Bottle (that can fit motor), Metal Sheet, electric wire connectors and connecting wires.

Step 3: Preparing the Bottle

  1. Take the plastic bottle and make three holes in it - one at the top for the motor, one in the center for the switch and one at the bottom for DC jack.
  2. Take a piece of wire and insert it through the bottle from top to bottom. Note: Make sure to watch the video for visual clarity.
  3. Solder the wire to the motor terminals.
  4. Take a DC adapter jack and solder the wires on the jack.
  5. Apply some Hot Glue and fix the jack at the bottom of the bottle.
  6. Apply some double sided tape around the motor, fix the motor inside the mouth of the bottle and close the cap tightly.
  7. Using Tweezers, pull the wire out from center hole.
  8. Cut one of the wire from the center and solder them to the push to ON switch.
  9. Using Hot glue, attach the switch at the plastic bottle.

It is now time to make a metal blade. Proceed to next step...

Step 4: Preparing the Blade

  1. Take a piece of metal sheet and draw two concentric circles of radius of about 4 and 5cm respectively.
  2. Cut the outer circle using metal scissors.
  3. Now, mark 18 equidistant points on both the circles.
  4. Draw the design of the cutting blade as seen in the uploaded image or the video.
  5. Using a metal cutting scissors, cut the blade very carefully.
  6. Drill a hole in the centre of the blade.
  7. Insert a small bolt and tight it on the blade using a nut.

Step 5: Connecting Blade to Motor

  1. Take the electrical cable connectors and remove the metal contacts.
  2. Attach one side of metal contact to the motor.
  3. Attach the blade to the motor using the other side of the metal contact.
  4. Secure and balance the joint with the M-seal adhesive around the metal contact.

Step 6: Testing the Dremel Cutter

Our powerful Dremel Tool is now ready. Connect a 12v DC power source and use the tool to cut any object.

    Yes, that can be easily done, you just need to attach a mini drill chuck (available on ebay and amazon) to the motor shaft and you get a nice mini drill machine.

    regardless of the definition of 'powerful', it is not only an interesting hack, but a semi useful project that someone might do to learn life hack skills such as working with epoxies and glue as well as some basic soldering skills, at the conclusion of which they have a tool of their own making sufficiently suitable for such tasks as model assembly or layout patterns for flat pack templates. Its all what you make of it... if there is not power in these lessons, then perhaps I am misunderstanding the meaning of power

    The word powerful here signifies that this is not a toy. It is a tool that actually works,

    only make sure that the M-seal adhesive applied is in equal proportions on all sides so that the blade does not vibrate. This tool cuts the pieces of cardboard, flex boards, PVC pipes, Fiber sheets and thin wooden ply boards like a piece of cake...
