DIY : Embed Speed Controller in Angle Grinder, - after converting an angle grinder to a circular saw

Converting an angle grinder to circular saw can be a money saving project. There are so many things we can do with angle grinders and we can also convert them into many useful tools such as converting angle grinder to belt sanders, drillers, routers etc. I have watched the videos, Diy circular saw from angle grinder | angle grinder hack |creative boss, and inspired, I decided to build one myself. I have also learned how to add circular saw blade fix angle grinder.
But when the angle grinder operates or run at very high PRM or speed, it makes us hard to use it as a circular saw. It might not be very safe and convenient for us to use it that way, so we need a speed controller. Some Bosch or INGCO or Makita angle grinders come with a speed controller but it’s more expensive than those without one. So I decided to build a speed controller or voltage controller for my circular saw that I converted from the angle grinder. The result is satisfying as in the cut test, I can have more control of the circular saw or angle grinder and feel safer. The way I build the cheap speed controller, make it possible to control the speed of drill machine or router etc.
Der Umbau eines Winkelschleifers in eine Kreissäge kann ein Geldsparprojekt sein. Es gibt so viele Dinge, die wir mit Winkelschleifern machen können und wir können sie auch in viele nützliche Werkzeuge umwandeln, wie z. B. Winkelschleifer in Bandschleifer, Bohrer, Oberfräse usw Winkelschleifer Hack |kreativer Chef, und inspiriert, beschloss ich, selbst einen zu bauen. Ich habe auch gelernt, wie man Kreissägeblatt-Fix-Winkelschleifer hinzufügt.
Wenn der Winkelschleifer jedoch mit sehr hoher PRM oder Geschwindigkeit arbeitet oder läuft, ist es schwierig, ihn als Kreissäge zu verwenden. Es ist möglicherweise nicht sehr sicher und bequem für uns, es auf diese Weise zu verwenden, daher benötigen wir einen Geschwindigkeitsregler. Einige Winkelschleifer von Bosch oder INGCO oder Makita werden mit einem Drehzahlregler geliefert, der jedoch teurer ist als solche ohne. Also beschloss ich, für meine Kreissäge, die ich vom Winkelschleifer umgebaut habe, einen Drehzahlregler oder Spannungsregler zu bauen. Das Ergebnis ist zufriedenstellend, denn im Schnitttest kann ich die Kreissäge oder den Winkelschleifer besser kontrollieren und fühle mich sicherer. Die Art und Weise, wie ich den billigen Drehzahlregler baue, ermögliche es, die Drehzahl von Bohrmaschine oder Router usw.

This is the same swtich we saw in new Bosch gws 900 125 grinder which has built in variable speed

[@backyard.craftsman]

I think it is but might not be as good as that of original Bosch.

[@arthurarfian4198]

hi .this is really good.. but if we add variable speed in our grinder.. set it at the lowest level (1).. is it affect the power of the grinder or no? coz when i use dimmer.. at the lowest voltage... it has no power....

[@backyard.craftsman]

I bought this speed controller from a local hardware store. It was designed for use with angle grinders, so at speed 1, it can still cut but at a much slower speed. I think dimmers are for light bulbs, not enough power for angle grinders. I think you can find one speed controller like this one on Amazon or Ali-express

[@arthurarfian4198]

@@backyard.craftsman awesome.. thanks for the info.... FYI, mine is dimmer speed controller 220volt....i thought the dimmer is voltage regulator..basically it`s works by declining the voltage... so the rpm will be down...but less power .... how about this variable speed? do you feel the power of your grinder still same at the level 5 and level 1.. even the rpm declining?

Can u show how to fix speed control switch in BOSCH GBL 620 Blower ,it's very useful for blower user

[@backyard.craftsman]

I am sorry that I haven't seen a Bosch blower in where I live. but If the speed controllers look the same it should be ok to replace it.

I have a build skill angel grinder so my question is if i made speed control to that grinder will my motor get damage plese tell

[@backyard.craftsman]

Thanks bro for the question. It wont damage the motor. This speed controllers are built for angle grinders. Some brand like Bosch sell angle grinders that come with this type of speed controller. I have used the one in the video for a few year and the motor is still running fine.

does your grinder has electrical
noise when you lower the speed?

[@backyard.craftsman]

Thanks for the question. No it makes less noise as it's spin more slowly.
