With Tormek device for machine planing knives SVH-320 you can grind HSS planing knives of any length. So suitable for miter punching. Thanks to this device you can always work with sharp planing knives. You no longer have to interrupt your work to send your planing knives away for resharpening. The jig is suitable for all lengths of planing knives. Blades longer than 270 mm are offset in the blade holder and sharpened in two steps. The tool is precisely guided and ground flat over its entire length to a preset fixed depth. This is not the case with the other Tormek jigs, where your hand decides where the grinding takes place and how deep it is ground. It is important that the grinding angle is set with great accuracy.
