Alright we got a new NPK #9 breaker and after a few hours of use ive already become frustrated. It has a chisel point which i did not want I wanted the blunt point as the material needs to fracture multiple directions not just across which is what the chisel point causes. The majority of the concrete needed broken is 8" thick and smaller and that is nothing for a chisel point. Being somewhat crafty i have was thinking why could i not weld a flat plate to the bottom say a chuck on steel that is 1ft square and 4-6" thick so more or less a plate tamper but on a breaker. I think this may give me the blunt contact i am after to fracture in multiple directions. Has anyone farminized a breaker like this to achieve the results your looking for?
