Fluted Spiral Reamer, #50
Graco reamer bit designed for cleaning the mix chamber nozzle. It features 4 smaller flutes at a 7-10 degree angle, making it much sharper than standard drill bits. This reamer can be used in a nozzle with hard foam. These are game changers for nozzles because they clean debris out of the mixing chamber much faster. They also take less pressure, which means they are less likely break inside the nozzle.
