The Glardon Vallorbe EnSet Hand Piece comes with 3 striker heads. Each striker head adds an additional power zone.
The hand piece works
Adjust the length for each graver stroke with the turn of the brass knurled wheel. Choose smooth bright cuts or traditional progress marks in your style of engraving. Longer strokes also provide more power, especially at low stroke frequencies.
Each hand piece comes with 3 collets for quickly changing gravers in your hand piece.
Consider purchasing a second hand piece when you frequently need to re-tune the hand piece between detail work and heavy tasks like inlay and background removal.
