Be Vertical
Keep the drill bits vertical to the object when drilling. Be sure to make both bit and work piece stable. Tilted bit is prone to break.

Control Speed and Pressure
It's recommended to use them with low speed and drilling pressure. The thicker the bits is, the slower speed and pressure should be taken.

Stay Cool
Friction will accumulate heat between bits and the work piece, add water or coolant if necessary.

Right Drilling Device
Please confirm the sizes before buying. Thick metals are recommended to be drilled with drill press, which is more stable and adjustable.
