Milwaukee M12 Drill Bits Demo on Different Surfaces (Wood, Ceramic, Metal and Concrete)

Different types of drill bit are used to drill different type of surface.
The most common type of drill bits are as follow
- Concrete
- Wood
- Metal
- Ceramic
To drill concrete, I normally used the Hammer mode on my drill to penetrate through hard surface easiy.
For wood, using drilling mode is more suitable with wood drill bit.
For metal, the drill bit is somewhat similar with the wood drill bit but it has slight difference which can be identified easily through its edge.
The Ceramic drill bit is designed differently, it has sharp drilling head to drill through the Ceramic without breaking it.
