User Guide：
❤Following some technique will let you save the bit:
1. Thin drill bits can break easily than thick bits, so drill more carefully while using a thinner drill bit, make sure it is perfectly straight.
2. Before start drilling, use some cutting oil. It will not only allow to drill hole easily but keep the drill bit from snapping off. It will also keep the drill from getting overheated and damaged.
3. Don’t push with much pressure since it can damage the drill bit.
4. Slowly start drilling the intro surface and then gradually increase the speed. Drilling with high speed at starting point can cause slipping off.
