When your .404" PICCO™ chains start going dull, the right file makes all the difference. The Stihl Round File 5.5 mm (7/32") — 3-pack gives you three hardened steel round files sized exactly to sharpen .404" PICCO™ chain cutters. These files are built tough to hold edge and resist bending or breaking under heavy use.
Each file in the pack fits the curve of the PICCO™ chain tooth, restoring the correct cutting angle without over-filing or damaging the edges. Because they're round files, they access the curved surfaces of the cutters better than flat files ever could. They're made from hardened steel — strong, durable, and built to last through countless sharpening jobs. (Stihl offers round files in diameters up to 5.5 mm for just this reason: to match larger chain pitches.) These files come bare (no handle), which lets you use them with your existing file holders, file guides, or sharpening systems without extra bulk. That means less gear to carry and no conflicts with what’s already on your rig. Keep your saw cutting fast, clean, and safe. Don’t let a dull chain slow you down. This 3-pack gives you spares on hand so when one file wears down or gets damaged, you’ve got two backups in your kit.
