Micro Air Turbine Tool (Cutter/Sander/Grinder)

Since i've made the turbine drill, i've been wanting to make something smaller and easier to hold. It's basically a dental handpiece converted to a dremel-like tool. It has reduction gearing from a micro helicopter to take advantage of the high speed of the turbine rotor. This micro tool though is more appropriate for model enthusiasts since it's a low power pneumatic tool with low torque and overall power.

Great job actually implementing your ideas into a (somewhat novel) but actually usable tool. Just don't go crazy with those RPM. The tool may survive but the cutting wheels could shatter (I realize you probably already thought of this but an extra reminder never hurts).

[@ale100f]

you are a genius *-* congratulations!!

[@nordenconrad14yearsago45]

nice work son.

[@ManualdoMotorStirling]

Congratulations friend, you are really making each amazing job! Greetings from Brazil, Leandro Wagner.

[@DatBlueHusky]

these tools are dirt cheap on ebay, makes me wanna get one and build a rc

[@killer251288]

very cool but now you make me curious can you make tuorial??

[@StirlingMaringa]

Excelente idéia. Parabéns !

[@myleswu9957]

someday, I'll build ironman arc reactor. kidding:) great video sir.

Really nice piece. Whilst it might not go up there in terms of power (observation made solely based on what i've seen IE there's not enough power to sustain cutting through that copper piece) it's clearly a good tool for jobs where you really need the extra space and maneuverability conventional dremel tools just don't have.

[@douro20]

They don't have a lot of torque compared to some of the newer electric dental drills which run at lower rpm but have better torque. These have a rated speed of around 300,000 rpm at the head.

[@MysticalDork]

I'm sure there are some fairly significant losses in the drive train of that thing, but you should be aware that those dental handpieces are designed to reach 600 thousand RPM. With a 7:1 reduction, even assuming 30% losses from system drag, that means that the cutting wheel is spinning at 60 thousand RPM; that's close to twice as fast as dremels go, and there is a very real hazard of the cutting wheel just disintegrating into extremely high-speed shrapnel and damaging your hand or face.

Guess someone has been to the dentist huh? :-D

[@wdowa94]

It would be great with working on some PVC

[@miguelangelbedoyagonzalez9166]

where I can get the handpiece, only the meeting to the turbine for part of the pinion?

[@mdragos27]

@johnny90: Just curious, where did you get the brass pinion gear from?

[@eucalyptux]

Where can i find those cutting disks ?

[@blackninja766]

What's the speed thing called to start the tool

[@friedmanirit]

Happy Forth Of July Lol!!!!!!!!!!!!!!!!

[@iamslendermanQ517]

Reminds me of a dentist tool.

[@kill1]

It was at one point.

[@iamslendermanQ517]

kill1 Alright. ;)

[@abrahamcontreras3520]

Hi johnnyq90, do you have any suggestions where I can get affordable dental turbine motors? Thanks

[@johnnyq90]

I buy mine on ebay

[@abrahamcontreras3520]

Awesome! Cool. Thank you.

[@inferno]

Most scarry shit i ever heard dam it

[@benscheding1304]

Is there any way to get these dental hand pieces for cheap?

[@johnnyq90]

Yes, I got mine from ebay for really cheap, $11-12.

[@Lobotryas100]

Звук вообще противный, как на приеме стоматолога.

[@mercedesbenz4454]

там винт от неё и стоит

[@Graiskye]

Ill stick with the dremel. Im not doubting your ingenuity and your deternination is obviously huge, I just dont see the point to most of your projects. Basically you have created a really needlessly complicated dremel tool. Dremel tools are something we have loads of variety and different types already available. Whats the point

[@TLHD420]

So why tell someone not to do something that they're passionate about? Why the fuck should we tell someone not to make something just because THEY WANT TO. And you question why this generation is full of incompetent idiots who don't know anything.
