Ep 3. Angle Grinders, Berry Baskets, and Omnidirectional Speakers

How It's Made season 21 episode 3 explores the manufacturing processes behind some handy tools and unique products.

The first segment dives into the construction of angle grinders, also known as disc grinders or side grinders. These versatile power tools are used for grinding, polishing, and cutting various materials such as metal, concrete, and tile. Viewers will learn how the grinder's motor and gears are assembled, as well as the importance of proper safety measures when using the device.
