PFERD Chain Saw Sharpener CS-X 7/32" File Kit — .404" Pitch, Preset 30° Guide & Depth-Gauge

The PFERD TOOLS CS-X chain saw sharpener (7/32") is a compact, manual sharpening kit that gives a consistent 30° edge and includes a depth-gauge file plus two Classic Line files for on-site chain maintenance.

When you need quick, accurate sharpening without sending chains to a shop or using bulky machinery, the CS-X from PFERD is built for the job. It combines a stable file guide, ergonomic handling and replaceable files so you can restore cutting performance on .404" pitch chains while removing minimal metal. The kit is designed for steels up to about 370 HV (≈38 HRC) and is ideal for users who want economical, repeatable sharpening with portable equipment.

How does the CS-X produce a consistent sharpening angle?

The CS-X holds the round file in a rigid, pre-set guide that accurately sets the cutting angle at 30°. That fixed geometry reduces user guesswork and delivers similar bevels across every tooth, improving cutting balance and chain life.

• Stable file position for uniform tooth bevels.
• Preset 30° guide ensures repeatable results.
• Designed for 7/32" files used on .404" pitch chains.
• Ergonomic housing helps steady the tool during strokes.

What comes in the kit and what chains does it fit?

This delivery includes one CS-X sharpener body, a depth-gauge file and two Classic Line round files sized 7/32". The tool is matched to chains with a .404" pitch and a recommended depth-gauge distance of 0.030".

• 1 × CS-X sharpener body for manual use.
• 1 × depth-gauge file for maintaining raker height (0.030").
• 2 × Classic Line round files, 7/32" diameter.
• Compatible with chains pitched .404"; steels up to 370 HV.

Why choose manual sharpening with the CS-X over machine sharpening?

Manual sharpening with a guided tool removes less material and is gentler on the chain than aggressive machine grinding. That means lower long-term costs and the ability to perform quick touch-ups in the field without specialized equipment.

• Conserves tooth material for longer chain life.
• Faster short repairs and on-site maintenance capability.
• Interchangeable files extend overall tool lifespan.
• Predictable, even sharpening even for inexperienced users.

How do I use and maintain the CS-X for best performance?

Use smooth, consistent strokes with light pressure, following the guide to reach each tooth’s correct bevel. Keep the depth-gauge at the specified 0.030" and replace files when worn to maintain sharp, efficient cutting edges.

• Clamp or secure the chain for safe, steady filing strokes.
• Check and adjust depth-gauge spacing as needed between sessions.
• Swap to fresh Classic Line files when the abrasive surface fades.
• Store dry to avoid corrosion and inspect the guide for wear.

Who is this for: The PFERD CS-X sharpener is aimed at homeowners, arborists, and professional saw operators who prefer a portable, economical sharpening solution. If you value consistent manual results, want to limit material removal, and need a small kit for field service on .404" pitch chains, this tool delivers straightforward, reliable maintenance without relying on power sharpening stations.
