The difference between Flute Notching and Chipping

"Flute notching or flute chipping" is defined as a "large chipped area" that occurs in the threaded part of the tap and the cutting edge chamfer portion. Chipping is defined as "small chipping" that occurs in the tap's cutting edge chamfer area but it is difficult to describe because it is can be a complicated problem to solve. You shouldn't be too concerned when telling others about a chipping problem, as any chipping will cause poor threads and tap failure. I think chipping is a useful word to explain "large and small" tapping trouble shooting problems. Please refer to the pictures shown below.
