When drilling, please ensure that the drill bit is installed in place without loosening. |
Cutting speed should not be too high, to prevent burning, rate should not be too large, to prevent the drill wear. |
Pay attention to safety during drilling, ensure protection. |
As the manual electric drill is rotating too fast, please pay attention to speed regulation. The larger the drill diameter is, the slower the rotating speed is required.
If the drilled material is too hard, first use a 3-6mm drill bit to make small holes, and then use a large drill bit to ream the holes.
The rotation speed of the electric drill for drilling hard objects should be between 80-120, and the effect is best.
Because stainless steel contains cracked alloy components, its hardness and mechanical properties are higher. When drilling with a hand drill, you need to apply enough pressure and enough motor power. It is easier to use a bench drill.
When drilling, conditionally add coolant or cutting fluid to cool down to reduce the damage of high temperature to the drill bit and extend the service life of the drill bit.
