Kohnkdllc 18 in Chainsaw Chains 3-Pack + 18 in Guide Bar .325 pitch, .063 gauge 68 Drive Links

This kit supplies three replacement chains and a single 18-inch guide bar engineered to match common Stihl household and professional models. The assemblies are manufactured from hardened German steel with controlled heat treatment and precision punching for improved flatness, wear resistance and consistent tension. Each chain is a 68 drive-link configuration sized .325" pitch and .063" gauge to work with a broad range of Stihl and compatible Oregon, Husqvarna and Carlton systems.

Which saws will these chains and bar fit?

These chains and the included guide bar are specified to replace OEM parts used on many popular Stihl saws and several cross-compatible brands. They list compatibility with Stihl models in the 017–025 series and numerous MS-series saws, plus equivalents from Husqvarna, Carlton and Oregon where the drive link count and pitch match.

• Designed for Stihl models: 017, 018, 021, 023, 025, MS 250, MS 251, MS 230, MS 241, MS 361, MS 362 and similar.
• Cross-references: Sthil part numbers 3639 005 0068, Oregon 22BPX068, Carlton K3C-68E and Husqvarna H26 68.
• Chain specs: 18" length, .325" pitch, .063" gauge, 68 drive links.

How does material and construction affect performance?

The kit uses German steel with a controlled heating process and precision punching to create consistent link geometry and uniform bar flatness. Rivets are hardened and quenched to lower wear and maintain tension stability over repeated use, which helps reduce stretch and the need for constant readjustment.

• Heat-treated steel improves toughness and longevity under load.
• Precision punching yields smoother chain fit and less wobble on the bar.
• Hardened rivets resist wear, keeping chain pitch and tension more consistent.

What should I check before installing these chains and the bar?

Confirm your saw’s nose-to-sprocket measurements and that the pitch and gauge match your saw’s sprocket and guide groove. Inspect the drive sprocket, clutch drum and oiling passages for wear or blockages; worn components can accelerate chain wear or cause poor cutting performance even with a new chain.

• Verify .325" pitch and .063" gauge match your saw’s sprocket and bar groove.
• Count or confirm the 68 drive links to match chain length for an 18" bar.
• Check sprocket, clutch drum and bar oil ports for wear or obstructions before mounting.

How should I maintain these chains for longer life?

Routine sharpening, correct tensioning and consistent lubrication will extend chain life. Use a compatible round file or sharpening system, keep the chain snug but not over-tightened, and ensure the bar oil reservoir feeds the chain during operation.

• Sharpen cutters when they become dull rather than overworking the saw.
• Set tension so the chain snaps back onto the bar but still rotates by hand.
• Refill bar oil and clean debris from the bar groove after heavy cutting sessions.

Who is this for: This Kohnkdllc bundle suits homeowners, landscapers and contractors who need multiple replacement chains and a spare 18" guide bar for frequently used Stihl-compatible saws. It’s a cost-effective option for keeping a saw fleet serviced, for chainsaw maintenance kits, or as a backup supply for off-grid or remote jobs where replacement parts are needed on short notice.
