IV. Usage and Maintenance Guide

[Correct Usage]

• Material Matching: Please select the appropriate drill bit or screwdriver bit according to the specific material (metal, masonry, wood, or screw fastening), and avoid forceful misuse. When drilling metals, it is recommended to moderately apply water or cutting oil for cooling to extend tool life.
• Tool Compatibility: Most drill bits in this set feature a hex shank design, perfectly matching standard hex quick-change chucks and various hand drills or impact drills.
• Speed Control: The larger the drilling diameter, the slower the drill speed should be adjusted. High-speed blind drilling is strictly prohibited to prevent tool overheating and damage.

[Daily Maintenance]

• Cleaning and Protection: After use, please clear any remaining wood chips, metal shavings, and debris from the surface of each accessory, keeping them clean and dry.
• Regular Oiling: If left unused for an extended period, apply a thin layer of anti-rust or lubricating oil to the metal surfaces to consistently maintain material performance.
• Storage Management: After use, please properly sort and return all accessories to the efficient double-layer storage case to prevent edge damage from collisions or component loss.
