Precautions on use

  • Use electric drills appropriate for the deck bit used.
  • Check that the main switch is turned off, and make sure to take out the power supply plug from the socket before attaching to or detaching from the motor or extension shank.
  • Product main body, swarf and drilling surface are hot due to friction in drilling. Never touch them with bare hands.
  • Wear work clothes suitable for the operation. In particular, wear protective glasses to prevent shavings from getting into your eyes.
  • Prepare the working environment before starting a job.
  • Carefully read the instruction manual for the motor used before use.
  • ■Titanium coated cutting edge

    Stable center positioning capability and long life have been achieved by a unique cutting edge shape, titanium coating on all the cutting edge, and small diameter point.
