The GC-CS 235 E saw chain sharpener is a compact, robust and reliable helper for the precise sharpening of all standard saw chains. Thanks to a swiveling clamp with scale for precise setting of the grinding angle, all the cutter links of the chain can be sharpened without repositioning. An adjustment facility for setting the roof angle increases the machine's range of application. A depth stop protects the chain from excessive material removal. Together with a lamp, the transparent window enables exact and safe operation even in poor daylight.
