KAKEI 20" Chainsaw Chain .325 Pitch .063 Gauge 81 Links — 3-Pack Full-Chisel Replacement for Pre‑2023 Stihl MS271 MS291 MS261

If you need reliable replacement chains for gas chainsaws that match specific Stihl bars, this KAKEI set offers three full‑chisel chains engineered for aggressive cutting and consistent performance. Each chain is manufactured from heat‑treated German steel, chrome‑plated for corrosion resistance, and finished with precision grinding to deliver sharp cutters out of the box. The pack is sized 20 inches with a .325" pitch, .063" gauge and 81 drive links — verify those measurements on your saw's manual or the bar stamp before ordering.

How do I confirm this chain fits my chainsaw?

Fit depends on four measurements on your saw or guide bar: pitch, gauge, length and drive link count. Inspect the guide bar’s stamped numbers or consult the owner’s manual for exact values, and match them to this chain’s spec sheet.

• Pitch: .325" (distance between drive links)
• Gauge: .063" (thickness of the drive link)
• Length: 20 inches (measure bar tip to nose)
• Drive links: 81 (count links that seat in the sprocket)

Why choose a full-chisel chain and what should I expect?

Full‑chisel cutters are square‑cornered and cut quickly through green and dry wood, making them a common choice for demanding felling and bucking tasks. They offer faster, cleaner cuts but require more frequent maintenance and careful handling due to increased kickback potential.

• Faster cutting rate than semi‑chisel designs
• Smoother, cleaner slices in solid timber
• Requires more frequent sharpening to maintain peak performance
• Higher kickback risk — use with proper training and safety gear

What manufacturing features improve durability and performance?

KAKEI combines heat‑treated German steel, hardened rivets, and Japanese chrome plating to improve strength, wear resistance and cutter life. Precision punching and grinding processes deliver consistent flatness and razor‑sharp cutters straight from the package.

• Heat treatment for improved toughness and reduced chain stretch
• Hardened, quenched rivets to resist wear and tension changes
• Chrome plating and rotary grinding for long‑lasting sharpness
• Protective oil coating to reduce corrosion during storage

How should I use and maintain these chains safely?

Follow manufacturer safety guidance and only install chains if the pitch, gauge and link count match your bar. Keep chains sharp, tensioned correctly and lubricated; worn or damaged chains should be replaced immediately to reduce risk of kickback and poor cutting performance.

• Check bar and chain fit before installing
• Use proper tension — not too tight or loose — before each cut
• Routine sharpening and lubrication extend life and cut quality
• Wear PPE and follow kickback‑aware cutting techniques

Who is this for: Woodcutters, homestead owners and professional users who operate Stihl chainsaws with a 20" .063" gauge bar and need fast, aggressive cutting. This three‑chain pack is a cost‑effective choice for frequent users who prefer full‑chisel performance and plan to maintain their chains regularly. If your Stihl bar uses a .050" gauge (some later MS271 bars), choose the matching .050" KAKEI models instead; otherwise, confirm the stamped specifications and order this 81‑drive‑link, .325"/.063" set for reliable replacement power.
