Disc flies off when grinder stops

We are using a threaded disc, rated at 13,000 rpm. The disc remains in tact and operates correctly until the operation is complete and the trigger is released. At that point the disc comes off the grinder and flies away from the grinder.

Disc flies off when grinder stops


Yes the above is correct with the question "are the threads the right size." but it can also be because u are not slowing the grinder down before stopping it. if the grinder stopps to soon the disk will stay moving. so the disk will fly off. i had the same problem with a pnuematic grinder. sometimes it is the operaters fault not the tools. " an object in motion aloways stays stays in motion till an outside force dissrupts it."

I have an older Black and Decker "Heavy Duty" 4 1/2" angle grinder (CAT 4246-09 Typ 1 SER 74136). I got it second hand and am not sure if you can help me because of that, but I have NO idea how to loosen the disc in order to replace it. I have had a couple of people look at it and they were stumped also. I would assume that there would be a button or a lever that would jam the disc to allow me to loosen the bolt/nut. I have a wrench that fits the rotating bolt below the disc, but like I mentioned, I have no clue how to prevent the disc from rotating while I loosen that bolt. Any help would be great. Thanks!


Give it a tip off a hammer and chicel will loosen it beter hit the spanner

Makita 9523NB angle grinder is suddenly suffering vibration and some emitted from motor before stopping. I have replaced brushes (original brushes were hardly worn) as 1 of the springs had little tension but the same problem persists. The grinder spins freely when the brushes are removed and also when inserted but as soon as it starts it vibrates badly. There is an insulation washer which is "Loose" I'm not sure whether this just sits in place or should be pressed onto the backing area of the grinder. Can you help????


You say it spins freely but is it smooth. If not it could be one or both of the bearings the armature spins on. More likely than not you have one or more fan blades broke or missing. Not much weight by themselves but at the speed these things spin the more blades broke off, the worse the vibration. You have to romove the brushes, take off the gear housing and remove the armature to check both the bearings and fan.

Bosch angle grinder stopped cold when tapped lightly


Yes, if you have taken the handle halves apart (unplug tool first) check with your meter thru the blades on the cord to the switch contacts and then lock the switch in the on position and check across the switch and then remove the brush caps and brushes and check thru to the brush holders, if at any time you lose continuity then that would be your problem. Let me know if I can help further.

Bosch angle grinder acts like its burnt out but motor resistance values suggest not


Hi Brian, running your angle grinder on reduced voltage (through overloading the petrol generator) will have caused the current in the grinder to be higher than it should be. This may not be what you expect, but it is a characteristic of rotating machines, they behave differently to resistive machines such as heating elements. You have not indicated how you come to the conclusion that the windings test OK. If you have just checked with an ohm-meter and see a continuity reading, this does not eliminate the possibility that the overheating resulting from over-current has broken down the insulation (evidenced by the smell and sparks) and you have short circuited windings. The grinder will run without a suppression capacitor, it is just there to minimise interference with you neighbour's (or your wife/girlfriend/daughter's :) ) radio. Replacing the capacitor will not restore your grinder, I reckon you have killed it, in spite of the fact that running it on a healthy supply was to quickest way to cool it effectively.
