| Setting the Blade Force |

| The blade force can be adjusted by the set screw (1) in the rear of the shank. The blade force has to be sufficient to extend the blade fully after passing the back end of the bore. This ensures that the blade can work with the necessary cutting performance. The tougher the material, the tougher the spring should be set. The blade force, however, does not influence the chamfer size. Working with the correct blade pressure increases the blade life and improves the chamfer quality. An extremely tough material requires a high spring force. For this purpose, the springs can be exchanged (SNAP5: GH-H-F-0041, SNAP8 and SNAP12: GH-H-F-0011). Turning the set screw clockwise increases the blade force (tough steel, Inconel, titanium). Turning the set screw counter-clockwise reduces the blade force (aluminium). |
