Warm Tips Before Use:

Be Vertical

• Keep the drill bits vertical to the object when drilling.
• Be sure to make both bit and workpiece stable. A tilted bit is prone to break.

Control Speed and Pressure

• When using bits with a power drill, it's recommended to use them with low speed and drilling pressure.
• The thicker the bits are, the slower speed and pressure should be taken.

Stay Cool

• Friction will accumulate heat between bits and the workpiece.
• Pay attention to the heat, add water or coolant if necessary.

Right Drilling Device 

• To avoid breaking, 1/16” and smaller bits are suggested to be used with a pin vise.
• Thick metals are recommended to be drilled with a drill press, which is more stable and adjustable.
