Product Highlights
- Set of 3 round files — covers the most common chainsaw chain sizes: 4 mm, 4.8 mm, and 5.5 mm
- Approx. 200 mm (≈ 8 in) file length — long enough for a firm, controlled stroke
- Made from bearing steel — high hardness and excellent wear resistance for long-lasting sharpness
- Sharp cutting teeth (fangs) — bite into dull cutters quickly and efficiently
- Smooth, round profile with a straight tang — follows the correct filing angle on every tooth for a clean, consistent cut
- Low-noise, simple hand-file design — no electricity, no special equipment needed
- Lightweight and portable — toss them in your toolbox, chainsaw bag, or backpack
How to Use
- Select the file diameter that matches your chain's cutter gullet (check your chainsaw manual or chain packaging).
- Tighten the chain tension so it is firmly supported on the bar.
- Place the round file in the cutter gullet at the correct filing angle (usually 30–35°).
- File each cutter from the inside outward using smooth, even strokes.
- Apply the same number of strokes to every cutter for a balanced, vibration-free cut.

Frequently Asked Questions
Q: What sizes are included in the round chainsaw file set?
A: The set includes three round sharpening files in 4 mm, 4.8 mm, and 5.5 mm diameters — the three most commonly needed sizes for consumer and professional chainsaw chains. Each file is approximately 200 mm (8 inches) long.
Q: What material are these chainsaw files made from?
A: They are made from hardened bearing steel, which provides high hardness and excellent wear resistance. This ensures the files maintain their cutting edges through repeated use and last significantly longer than standard carbon-steel files.
Q: How do I know which file diameter to use on my chainsaw chain?
A: The correct file diameter depends on your chain's pitch. Common pairings are: 4 mm for 1/4" and 3/8" low-profile (LP) chains, 4.8 mm for 3/8" standard chains, and 5.5 mm for 0.404" chains. Always check your chainsaw's manual or the chain packaging for the manufacturer's recommended file size.
Q: Can beginners use these chainsaw files?
A: Yes. The straight tang and round profile make them intuitive to use. Simply tighten the chain tension, align the file at the correct angle in the cutter gullet, and use smooth forward strokes. A filing guide (sold separately) can help beginners maintain a consistent angle for best results.
