UPFOREST Chainsaw Chain 18-inch .325 Pitch 74 Drive Links (3-Pack) Full-Chisel, .063 Gauge - Hardened Steel

UPFOREST 18" full-chisel chainsaw chains (74 drive links, .325" pitch, .063" gauge) are a 3-pack replacement made for Stihl-compatible saws such as MS271, MS291 and MS311, engineered for aggressive cutting and longer edge life.

These aftermarket chains are built to match the common Stihl 18-inch setup for 38–62 cc saws using .325" pitch and 1.6 mm gauge bars. Each chain in the pack is manufactured from hardened German steel, chrome-plated cutters and precision-formed rivets to resist wear, maintain flatness and reduce tension shifts during operation. The set also comes with light protective oil applied to help prevent corrosion in storage and transit.

Will these chains fit my saw and bar?

Compatibility depends on three key dimensions: pitch, gauge and count of drive links. This UPFOREST chain is .325" pitch, .063" (1.6 mm) gauge and has 74 drive links — a common fit for many Stihl 18" bar setups, but always verify your saw's specifications before purchase.

• Pitch: .325"
• Gauge: .063" (1.6 mm)
• Drive links: 74
• Common fit: Stihl MS271, MS291, MS311 and similar models

How does the build quality affect cutting performance?

These chains use heat-treated German steel and hardened, quenched rivets to improve toughness and maintain chain flatness under stress. Cutters receive a chrome plating and precision grinding for sharper initial edges and better durability between sharpenings.

• Heat-treated steel for strength and reduced deformation
• Hardened rivets to limit wear at pin joints
• Chrome-plated, CNC-ground cutters for sharper edges
• Protective oil coating to resist corrosion during storage

What maintenance and sharpening should I expect?

Full-chisel cutters deliver fast, aggressive cutting but blunt quicker than semi-chisel types on dirty or frozen wood, so routine sharpening is important. Use the correct round file size and follow your saw manufacturer's tension and lubrication guidance to extend chain life.

• Sharpen with the proper round file and depth gauge tool
• Check and adjust chain tension before each use
• Keep bar and chain properly oiled during operation
• Avoid cutting dirt, nails or heavily frozen wood which accelerates wear

Why buy a 3-pack instead of a single chain?

Buying three chains gives you spare blades for longer projects, reduces downtime when one chain needs sharpening, and can be more economical per blade. If you run your saw frequently or in professional settings, having backups ready preserves productivity and avoids last-minute sourcing.

• Immediate backup when one chain needs service
• Lower cost per chain versus single purchases
• Convenient for multi-shift or large-volume cutting jobs
• Packaged with protective oil to prevent rust while stored

Who this is for: The UPFOREST 18" 74-drive-link full-chisel 3-pack is suited for homeowners, landscapers and professional arborists who use Stihl-compatible saws in the 38–62 cc range and want aggressive cutting performance plus multiple ready-to-use chains. Choose this set if you need fast-cutting full-chisel cutters and the convenience of spare chains, but if you frequently cut dirty or frozen wood consider a semi-chisel alternative for longer edge retention.
