Slotdrills are the 2 flute cutters primarily used for milling keyways and slots. They can plunge downwards to depth in a drilling action. Slotdrills do not have a+ tolerance on diameter size so won"t ever cut oversize. Endmills, on the other hand can be 4, 6 or 8 flutes, generally for milling along 90' edges or finishing side walls. slot bet besar
