Interchangeable Blade Countersink Tool For Large Chatter-free Countersinks The GH-K has three exchangeable countersink blades which are precision-ground as a set to achieve unmatched countersink finishes. Positive geometry allows for high shear cutting action. The tool feeds the coolant through an inner supply duct directly to the blade. The GH-K has an alloy heat-treated steel tool body and integrated internal coolant. The blades are made of coated carbide and can be resharpened or replaced. These cutting edges extend almost to the countersinking tool tip, providing a wide countersink diameter range. The three carbide cutting edges and three insert seats in the tool body are manufactured to extremely tight tolerances. |
| Countersink range from Ø3.0 – Ø25.0 mm or Ø4.0 – Ø45.0 mm. Three interchangeable, precisely matched carbide blades. Internal cooling available, Circular milling possible . The countersinking tools are available with countersinking angles of 60° and 90°. Two types: a countersinking tool with three cutting edges and a countersinking tool with only one cutting edge. Each design is available in two versions with a countersink diameter range from 3.0 – 25.0 mm and another from 4.0 – 45.0 mm. |
