<prompt> Feature of a NiTi file that a surface project axially from the central core to the cutting edge between the flutes is known as:TaperLandPitchRake angle  <response>: Land:It is the area between the flutes which projects axially from central core to the cutting edge.Rake angle:It is the angle formed by leading-edge with the radius of file. Acute angle is considered as a negative rake angle and obtuse angle is considered as a positive rake angle.Taper:It signifies per millimeter increase in file diameter from the tip towards handle of file.Pitch:It is the distance between two cutting edges. A file with short pitch has more flutes when compared to file with longer pitch.
