1. Hand drills must be used carefully - although they are manually operated they can still cause injury.
Always clamp all material being drilled to a workbench using a G-clamp.
Place scrap wood underneath the material being drilled just in case the BIT passes through into the bench top.
The hand drill is held vertically. One hand holds the handle at the top whilst the second hand rotates the other handle in a clockwise direction. This turns the chuck and drill bit.
Only light pressure should be used to push down on the hand drill, if a lot of pressure is needed the drill bit is probably blunt (change it for a sharp drill bit).

2. Your work should always be held firmly by using a machine vice, hand clamp or g clamp. Reuse a scrap piece of wood to protect the metal drill table.
SAFTY
Make sure the work is held in a machine vice or clamp
Wear safety glasses
Make sure the drill bit is secure in the chuck and the chuck key is removed.
Use the machine guard
Make sure you know where the stop button is located.
Only two students to work on the machine.
Read the safety card

Twist drill
Twist or flute carries material away in the form of swarf
Available is sizes from 0.5mm diameter to over 25mm
Small drills prone to breaking if not used correctly. Can become blunt at high speeds.
Flat bit
Used to drill a hole all the way through, but will break through, splintering wood on underside
Fast removal of waste with an electric drill
Will split wood on underside when drill bit breaks through if not supported by another piece of wood.

Countersink bit
Creates depression for head of a countersink screw so that it sits flush with surface of material
Can be used to create range of countersink hole sizes
Will chatter if used at too high speed or if not located in centre of hole properly.
Forstner bit
Used on thin materials or to make large hole to 50mm in diameter used in a pillar drill.
Used by many to make precise holes in flat surfaces. I.e. speaker project.
Have tendency to burn or bind if used at too high speed.
