Buying Guide For 20 Inch Chainsaw Blades
Compatibility With Chainsaw Model
Ensure the chainsaw blade matches your chainsaw specifications. The important aspects include bar length (20 inches here), pitch (typically .325″ or 3/8″), gauge (usually .050″), and the number of drive links. Cross-reference these parameters with your chainsaw model for a perfect fit.
Pitch And Gauge
Pitch refers to the distance between drive links. A .325″ pitch is common in medium-sized saws, offering faster cutting with more frequent chain sharpening. A 3/8″ pitch is suited for heavier-duty work with compatible saws. Gauge measures chain thickness fitting the guide bar groove; .050″ is standard for most chainsaws in this size range.
Chain Type: Semi-Chisel Vs. Full-Chisel
Chainsaw chains are mainly available as semi-chisel or full-chisel. Semi-chisel chains, commonly found in the featured products, are easier to maintain and better for dirty or rough wood due to their rounded teeth. Full-chisel chains cut faster but dull quickly in dirty conditions and require more frequent filing.
Drive Links And Chain Length
Drive links should match your guide bar’s engagement area. Too few links reduce chain retention, while too many create excess tension and wear. Most 20 inch chainsaws use between 70-80 drive links, with the exact number specified in the chainsaw manual.
Low Kickback Features
Safety can be improved with low-kickback chains. These chains typically have design modifications such as guard links reducing the risk of sudden upward chain movements. This feature is critical for less experienced operators or residential use.
Durability Enhancements
Look for chains with hardened rivets and heat-treated cutters. Chrome plating or special coatings can improve chain life and reduce wear. These features mean fewer chain adjustments, longer maintenance intervals, and better reliability.
Value Packs Vs Single Chains
If you use your chainsaw frequently, value packs like the 2-pack Husqvarna SP33G chains offer cost savings and convenience. However, single chains are suitable for occasional users or backup replacements.
