Read Warm Tips Before Use
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
When using bits with a power drill, 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 work piece.
Be aware of 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
drill press
, which is more stable, and adjustable
To have the best performance, you shouldn't drill deeper than 1/2 of the drill bits' fluting length
