IV. Operation & Maintenance Guide
【Proper Usage】
- Material Compatibility: Designed specifically for general thin iron sheets (~2mm), thin sheets, wood, and plastics (Caution: Not suitable for aluminum). When drilling metal, appropriate water or cutting fluid cooling is recommended to extend tool life.
- Tool Compatibility: Standard 6.35mm hex shank design, compatible with various quick-change chucks and power drills for fast and convenient assembly/disassembly.
- Speed Control: Adjust drill speed lower for larger hole diameters. High-speed blind drilling is strictly prohibited to prevent overheating and bit damage.
【Routine Maintenance】
- Cleaning & Protection: After use, clean out any residual metal chips and debris from the flute, wipe clean with a cloth to remove oil, sweat, or cutting fluid, and store in a dry environment.
- Regular Oiling: If left unused for an extended period, apply a thin layer of rust-preventive or lubricating oil on the metal surface to preserve material performance.
- Storage & Management: After single-piece use, it is recommended to store them properly in a moisture-proof tool box or dedicated drill rack to avoid edge damage from impacts.
