• Collet, 3 jaw chuck
  • Faster
  • Better gripping

• Long WP
• Manual operations -> motors CNC
• Lower quantity
• R&D -> manual | CNC -> mass production

Milling

• In-feed
• CNC is more common
• HSS, carbide, carbide tip
• Drilling needs less accurate tolerance, flexible tool, using end mill could lead to oval shapes or eccentric holes

Drilling

• Interference, sleeve - 3-jaw drill chuck
