With the Shrink Unit MS 3.0 sensitive, thin-walled shrink chucks are shrunk gently with enough energy to avoid overheating the chucks. Small milling cutters with a diameter of 0.04mm to 0.01mm have a shank diameter of 3, 4, or 6 mm. This shows another strength of Diebold products. Shrink chucks with a 3 mm bore are not easy to manufacture so the shrink process works reliably. These milling cutters are very sensitive and may not come into contact with cooling sleeves so they are not destroyed. Diebold is known for the exceptionally high quality of its products. That is why the best-selling items from the extensive range are shrink chucks with a diameter of 3 mm.
