1. Before drilling, it is necessary to ensure that the cutter is fully installed without loosening or clamping.

2. When drilling with a magnetic base drill, it is necessary to ensure that there are no iron chips under the magnetic block of the drill, the adsorption surface is smooth, and the machine does not sway or not absorb completely.

3. The whole process from the beginning of drilling to the completion of drilling should be kept fully cooled. Internal cooling is the best method when conditions permit. Insufficient cooling can easily cause tool damage.

4. Drilling should start slowly and smoothly at the beginning. After entering 1-2mm, the feed speed can be increased. Slow down the speed of the knife while cutting, and keep the feed evenly in the middle cutting process.
