*1: Because it has no side handle, but has a hose, the coolant does not turn. Usable.
*2: Because it has no side handle, it must be fixed separately before use.

  • If the electric drill produces a low output, its rotation will stop, thus disabling drilling.
  • Never stop drilling halfway through completion. (The cutting teeth may get broken.)
  • If the cutter becomes dull during drilling for some reason, make filing by drilling several holes in a block, GC stone, etc.
  • For dressing (filing), it is recommended to use our dressing plates. (Click here)
