KAKEI Chainsaw Chain 20-inch .325 pitch .050 gauge 3-pack — 81 drive links, full-chisel cutters

KAKEI 20" .325" pitch, .050" gauge full-chisel chains — three ready-to-install chains for Stihl-post-2023 bars with 81 drive links.

If you need replacement chains for mid-size Stihl saws like MS271 Farm Boss, MS291 or MS261 that accept a 20" bar with .325" pitch and .050" gauge, this KAKEI 3-pack supplies durable, sharp full-chisel cutters and the correct 81 drive-link length. These chains are engineered with hardened rivets and chrome-plated cutters to resist wear, and they arrive pre-oiled for corrosion resistance. Before ordering, confirm your guide bar stamp or owner's manual lists .050" gauge — some older Stihl bars use .063" gauge and will not fit these chains.

How do I confirm this chain fits my chainsaw?

Fit requires matching four dimensions: pitch, gauge, drive links, and bar length. Check the guide bar side stamp or your saw manual to confirm a 20" bar, .325" pitch, .050" gauge and 81 drive links. If any value differs, pick the chain that matches those numbers.

• Find pitch and drive-link number stamped on the bar or in the manual.
• Measure gauge at the groove with a feeler or view the bar stamp.
• Contact KAKEI support with your saw/bar part number for help.

What performance can I expect from the full-chisel cutters?

Full-chisel cutters bite aggressively and cut quickly through green and dry wood, delivering fast productivity for felling and crosscutting. They sharpen to a keen edge and maintain cutting speed, but full-chisel chains are more susceptible to dulling when they encounter dirt, nails or frozen wood compared with semi-chisel designs. Routine inspection and frequent filing keep cutting performance high and reduce vibration.

• Fast, square-corner chip removal for rapid cutting.
• Chrome-plated cutters resist corrosion and extend sharpness.
• Re-hardened rivets maintain chain tension and reduce wear.

How durable are these KAKEI replacement chains?

KAKEI builds these chains from German steel with controlled heat treatment and hardened, quenched rivets to improve toughness and flatness. Japanese chrome-plating on the cutter faces plus factory sharpening produce durable, corrosion-resistant cutters. Proper lubrication, correct tension and avoiding contact with ground or foreign metal will maximize life.

• Heat-treated steel and quenched rivets for strength and wear resistance.
• Factory-ground cutters and chrome plating for longer edge life.
• Ships with protective oil to limit surface rust in storage.

What safety and maintenance points should I remember?

These chains are capable of kickback; only experienced operators who know kickback avoidance and safe saw handling should use full-chisel chains. Keep the chain tensioned to the manufacturer's specification, check sprocket and bar wear, and replace or sharpen cutters before they become dangerously dull. Use personal protective equipment and follow all chainsaw and local safety regulations.

• Verify correct tension and inspect for cracked links or loose rivets.
• Sharpen with the right file size and maintain the depth gauges.
• Do not use on bars marked .063" gauge — measure before installing.

Who is this for: This KAKEI 3-pack is intended for homeowners, landscapers and professional users who operate Stihl models (post-2023 .050" gauge) requiring a 20" chain with 81 drive links and who favor high-cutting-speed full-chisel performance. Choose this set if you want three ready-to-install chains with corrosion protection, hardened rivets and factory-ground cutters — and be sure your bar gauge is .050" before purchase.
