How to use
Secure the drill bit into the drill chuck or press collet and tighten firmly. Select an appropriate rotational speed and feed rate for the metal type being drilled; lower speeds are generally used for harder metals. Use cutting fluid or lubricant to reduce heat and prolong tool life during drilling. When drilling deep or through holes, clear chips regularly to prevent clogging and maintain hole accuracy. After use, clean and store the bit in a dry place to avoid corrosion.
Использование и уход
For best results, match drill speed and coolant to the workpiece material, and inspect the bit for wear before each use to ensure accurate holes and safe operation.
