Features: Equipped with an initial position setting mechanism for the knurled holding part.Automatic alignment (±2.5mm from the initial position) by the upper and lower auto-slide mechanisms eliminates the difference in rolling force generated on the two knurling pieces, enabling knurling with uniform groove depth.This is a holder for rolling type knurling and waviness processing.
Purpose Compatible models: Shank diameter: 20 x 20 mm.
