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 pressureThe thicker the bits is, the slower speed and pressure should
be taken Stay Cool Friction will accumulate heat between bits and the work
piecePay 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 viseThick metals are recommended to be drilled with drill
press, which is more stable and adjustableTo have the best performance, you
