2. Chuck (engineering) - Wikipedia

   en.wikipedia.org/wiki/Chuck_(engineering)

   A backplate with threads may screw onto a threaded spindle nose (for lathe work) or onto an adapter plate with the same nose, to be mounted on the table of milling machines or surface grinding machines. This "threaded spindle nose" type of mounting was the typical method in the 19th century through 1930s.

3. Machine taper - Wikipedia

   en.wikipedia.org/wiki/Machine_taper

   Spindle nose on a lathe headstock. The small female taper is a Morse taper to take a lathe center or a tool such as a twist drill. The large male taper takes a lathe chuck, which is retained by the large nut. A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool.

4. Drill bit shank - Wikipedia

   en.wikipedia.org/wiki/Drill_bit_shank

   The Morse taper allows the bit to be mounted directly into the spindle of a drill, lathe tailstock, or (with the use of adapters) into the spindle of milling machines. It is a self-locking (or self holding ) taper of approximately 5/8" per foot [ 3 ] that allows the torque to be transferred to the drill bit by the friction between the taper ...

   where is the tap drill size, is the major diameter of the tap (e.g., 3 ⁄ 8 in for a 3 ⁄ 8-16 tap), and / is the thread pitch (1 ⁄ 16 inch in the case of a 3 ⁄ 8-16 tap). For a 3 ⁄ 8 -16 tap, the above formula would produce 5 ⁄ 16 , which is the correct tap drill diameter.

7. Spindle (tool) - Wikipedia

   en.wikipedia.org/wiki/Spindle_(tool)

   A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles.
