Broken on/ off switch for rockworth ARPD1700 hammer drill

Try motor rebuilding/repair shops or ebay for brushes.

The ring of the impact bolt in front inside the locking sleeve where the chisel is driven on can be blocked (also broken part ) but not to see until you remove the parts .

This is usually indicative of a broken wire in the cord near the handle. Plug the tool in, hold the trigger on and pull the cord in different directions near the handle. If it cuts off & on, one or more of the wires in the cord are broken and it should be replaced.

The hammer inside the drill head are most likely damaged ans/or broken, it is likely the best thing to do is just replace the tool.

I have seen many versions of this hammer with many different mfg names. I believe that this is a China copy of a hitachi hammer. No parts are available for this tool. The tool looks substantial from the outside, however internal parts are weak and break/burn out very easily (unlike the Hitachi/Japan version which is a workhorse, years of use before failure). If your hammer is china version, do not invest any more money because other parts will start to fail (most fail within short time from motor burn or broken parts ).

your pin under the selector switch my have broken off. also the hammer rod could have broken too. if its drilling and not hammering that more likely. you may be under warranty call bosch or log on and go to dealer locator's for the closes dealer to you. hope this helped

The problem was the cord at the base of the drill. The wires were broken, cause by constant bending. After souldering the wires, the drill works perfectly.

Thanks.
