Operation in Mode B
  • Mode A (Self-Tapping Screws): Optimized for metal self-tapping screws. The tool automatically detects resistance and slows down or stops to prevent stripping the screw head or damaging the material.
  • Mode B (Wood Screws): Optimized for wood screws. The tool manages torque and speed to ensure the screw is driven flush without splitting the wood or over-driving.

Auto-Stop and Safety Features

The tool includes intelligent auto-stop and auto-slow-down functions to enhance precision and safety:

Auto Bolt Release and Shut-off features
Auto Bolt Release and Shut-off features
  • Auto Shut-off: Automatically stops the tool when the fastener is fully seated or when a specific torque threshold is reached.
  • Auto Slow Down: Reduces the impact speed as the fastener approaches the surface to ensure a clean finish.
  • Auto Bolt Release: Specifically for bolt applications, this feature stops the tool immediately upon detecting that the bolt is loose, preventing it from falling off.
