So my 2604 milwaukee which has been overworked turning an 7.5 kdrill is starting to fade i want to switch it out for 2804 , my understanding is that drill won't work with that plates adapter 2604 has 1/2" threaded shaft and 2804 is an 9/16 threaded does anyone know if i can switch the adapter shaft ? or should i just start over and buy all new rather kinda like this setup with no chuck to worry about it's a direct bolt on with drill dedicated to it and i like it that way . but if it's a 5 dollar fix that'd be cool
