Fig. 6 Paddle bit or spade bit

Paddle bits are used to make a hole similar to the forstner bit, but they
don’t cut as cleanly.

Fig. 7 Masonry bit

Masonry bits are used for drilling into block, brick, stone, tile, or
concrete. Because of the hardness of the material that masonry bits are
used in they are best suited for power drills.

Fig. 8 Auger bit

The auger bit is great for making medium to large size holes in wood.
With its chisel like cutting edges, the auger bit cuts a clean flat-bottomed
hole, much like the spade bit and forstner bit. The deep flutes on an
auger bit pull the chips and dust up out of the hole it’s cutting, making it
ideal for cutting deep holes. Because of the pulling action of this bit
when it contacts wood, it’s best to only use it in a hand drill.

Fig. 9 Hole saw

Hole saws are used for cutting large diameter holes in wood or plastic.
These are best used in power drills at slow speeds.
