Morse taper is usually used in bores of spindle noses of lathes and drilling machines, shanks of drills, reamers, centres, etc. The Morse taper is denoted by the letters MT. It is available from MT0 to MT7. The numbers MT0 to MT4 are commonly used on taper shanks of twist drills, reamers and lathe centres. The included angle of the Morse taper is approximately 3° and the taper per foot is 5/8 inch.
