Key Components Include:

  • Housing: Protects gears and keeps the spindle stable under load.
  • Bevel Gears: Redirect rotational motion at the required angle.
  • Bearings: Maintain smooth rotation and prevent wobble.
  • Spindle Shaft: Transfers power directly to the tool.
  • Locking Mechanism: Holds the angle head securely in place.
  • Tool Holder Interface: Connects drill bits or cutters to the spindle.
