I have a particular tool and cutter grinder. Its head is noisy, in
fact, its noise resembles the sound of a rotary siren (though not as
loud). Would you say that the most likely cause of it is bad bearings?

Either in the head or in the motor


Makes a lot of sense

If the motor is tied directly to the spindle..remove the motor and
run. If you still hear the squealing..check the sheetmetal around the
fan and see if it got dented. If it still squeals...hold a long screw
driver to the bearing areas on each end and put the screw driver
handle in your ear for a stethescope.

If it comes from the spindle...pull the bearings AND MAKE A DRAWING of
it being disassembled (or take photos as you remove each part) and
order and install new bearings
