Flo 79863 file/rasp

Flo 79863 file/rasp by Vorel is a set of three round sharpening files designed for routine maintenance of chainsaw chains with smaller-pitch cutters. Each file is 200 mm long and has a 4.8 mm diameter, suitable for restoring the cutting edges of chains with 3/8" low profile and 1/4" pitch configurations. The metal construction and round cross-section make these files appropriate for filing the curved profiles of cutting teeth to maintain consistent performance and prolong chain life.

Advantages

The set contains three identical round files, offering spare tools for multiple sharpening cycles or extended service life. The 4.8 mm diameter matches the recommended size for the specified chain pitches, ensuring accurate contact with the cutter profile. A 200 mm length provides sufficient working area and grip distance for controlled use. The files are compatible with common manual sharpening techniques and can be used in field conditions without special equipment.

• Field and workshop maintenance of chainsaw cutting teeth

How to use

Secure the chainsaw bar and chain before sharpening, following the chainsaw manufacturer's safety instructions. Place the round file on the curved face of each cutter at the correct filing angle and use steady, even strokes in the direction of the cutter's cutting edge, maintaining consistent pressure. File each tooth the same number of strokes to preserve balanced cutting geometry. After filing, inspect the depth gauges and, if necessary, dress them to the recommended height with the appropriate tool.

Usage recommendations

Use protective gloves and eye protection while sharpening. Replace files when the cutting surface becomes worn or rounded and no longer restores the cutter profile effectively. Store the set in a dry place to prevent corrosion and keep files together to avoid loss.
