Stay Cool
- Friction will accumulate heat between bits and the work piece
- Pay attention to the heat, add water or coolant if necessary.
Right Drilling Device
- To keep away from breaking, 1/16” and smaller bits are suggested for use with a pin vise
- Thick metals are advisable to be drilled with drill press, which is more stable and adjustable
- To have the most efficient performance, you should not drill deeper than 1/2 of the drill bits’ fluting length
