I am a concrete cutter in phoenix arizona and i have a dirty job. I use a number of different pieces of equipment. I have a 35hp slabsaw that cuts either asphalt or concrete i have a coredrill that drills holes in ceilings floors or walls. I also have a hydraulic handsaw that allows me to cut windows and doors in block and brick and concrete walls. There are a number of other tools that i use. I get dirty when I wallsaw or handsaw doors or windows. overall my job is tiring and dirty i get covered in concrete slurry.
