Read Warm Tips Before Use
Keep the drill bits vertical to the object when drilling
Be sure to make both bit and workpiece stable. Tilted bit is prone to break
Control Speed and Pressure
When using bits with a power drill, it is recommended to use them with low speed and drilling pressure
The thicker the bits is, the slower speed and pressure should be taken
The bigger the step is, the slower speed and pressure should be taken (1000r/s-150r/s)
Friction will accumulate heat between bits and the material being drilled
Pay attention to the heat, add water or coolant if necessary
Right Drilled Material
Certificated as 60 HRC. DO NOT USE to drill material whose hardness is same as or higher than our product
Thick material are recommended to be drilled with drill press, which is more stable and adjustable
For high-efficient drilling, thickness of material shall be less than that of each step
