I need to do some surgery on some overhead cabinets to provide more clearance height for a newer refrigerator and picked up a Fein Multimaster the other day. I've got a fairly clear plan on how I need to do the remodel but after reading through the Fein manual and DVD I'm not real clear on which blade attachment I should be using to cut into the cabinets and shelf. What sort of considerations do you use to decide whether to use one of the E-cut type blades with the step in the blade vs. the flat round HSS type blade. Also, does anyone know what the difference is is between the standard E-cut blades vs the precision E-cut blades? Is that just a finer TPI for the precision blades on the cutting edge?
