Any one ever came accross any adaptors or the likes, that you can fit to a hammer drill, that would stop rotation and just leave the hammer function active like a chisel function on the bigger drills?
I assume that you are talking about an older mechanical impact drill, not an SDS drill. The strength of blow on an SDS drill is many times that of a mechanical impact drill, hence the eventual adoption of a rotation stop mode on almost all modern SDS drills (early SDS drills in the 1980s lacked this functionality). Any rotation stop needs to be incorporated on the gearbox of the tool, but the paltry blow strength of mechanical impact drills makes this a pointless exercise. Because this mechanism is within the gearbox on SDS drills it is not possible to retro fit rotation stop to them
There is an SDS bit that cab be used in flushing radiators, on the chisel setting, that is essentially there to vibrate the radiator and loosen up the dirt inside, It doesn't need the power of actual big drills that you would use for chiseling out walls etc, had hoped there might be an adaptor that would allow for a cordless drill to use the rotary hammer setting and fit the bit to it without it actually rotating, but that answers my question thanks.
Basically while flushing the radiators you use this in an SDS on chisel function along the bottom of the radiator and it lossens and lifts dirt into the flowing flush water, makes a huge difference to flushing a system. Loud as hell though
Sounds a bit like the tamping bits you used to get with the older style Kango breakers - basically a shaft with a flat rectangular bit welded on the end. Used to tamp small areas of hard core and also on the outside of shuttering to vibrate air pockets to the surface, etc. They were expensive, too, which is why you used to see home made ones welded up from a lump of thick black steel plate welded into the end of a worn out or broken chisel or concrete point.
Sorry I couldn't help with the rotation stop, but SDS drills took over that area 25 years or so back
