The Skinny on End Mills

Spindle speed that is too slow paired with a faster feed rate can result in dulling of the cutting edge deflection of the end mill and possibility of breaking the end mill A good strategy when selecting a cutter is to attempt to balance feed rate and spindle speed by performing two passes on the work piece
