Ideal for setting stones, this set includes 18 concave, tempered punches. Simply insert the stone, then press the punch directly over the prongs to securely set. The concave-shaped design will push your prongs evenly, and gently – especially fragile stones. Works with stones that measure from .75 mm up to 7.75 mm in diameter. Comes in a convenient wooden storage box for easy organization and identification (the storage holes are clearly marked).
