2. Tipped tool - Wikipedia

   en.wikipedia.org/wiki/Tipped_tool

   The advantage of tipped tools is only a small insert of the cutting material is needed to provide the cutting ability. The small size makes manufacturing of the insert easier than making a solid tool of the same material. This also reduces cost because the tool holder can be made of a less-expensive and tougher material.

3. Tool bit - Wikipedia

   en.wikipedia.org/wiki/Tool_bit

   There are different types of form tools. Insert form tools are the most common for short- to medium-range jobs (50 to 20,000 pcs). Circular form tools are usually for longer jobs, since the tool wear can be ground off the tool tip many times as the tool is rotated in its holder. There is also a skiving tool that can be used for light finishing ...

4. Machine taper - Wikipedia

   en.wikipedia.org/wiki/Machine_taper

   The collets or tool holders are placed directly into the spindle and the drawbar is tightened into the top of the collet or tool holder from above the spindle. Other tools such as drill chucks, fly cutters, indexable insert cutters, etc. may have an R8 taper shank built into or added to the tool.

5. Boring (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Boring_(manufacturing)

   Boring is one of the most basic lathe operations next to turning and drilling. Lathe boring usually requires that the workpiece be held in the chuck and rotated. As the workpiece is rotated, a boring bar with an insert attached to the tip of the bar is fed into an existing hole. When the cutting tool engages the workpiece, a chip is formed.

6. Cemented carbide - Wikipedia

   en.wikipedia.org/wiki/Cemented_carbide

   As well, modern turning (lathe) tooling may use a carbide insert on a carbide tool such as a boring bar, which are more rigid than steel insert holders and therefor less prone to vibration, which is of particular importance with boring or threading bars that may need to reach into a part to a depth many times the tool diameter.

7. Chuck (engineering) - Wikipedia

   The closer on a manual lathe is either lever-style or handwheel-style. The closer on a CNC lathe is powered (electric, hydraulic, or pneumatic), and it may be controlled by various means: a foot pedal that the operator steps on when desired; a line in the program (for opening and closing under program control); or a button on the control panel.
