Series E: Narrow Kerf Chains for Battery-Powered Saws
Standard catalog Series E is low profile, semi-chisel, .043" gauge only, in .325" and 3/8" LP pitch, with 65Mn steel—see the product catalog MDM list for exact drive-link counts. Other gauges and pitches are not Series E catalog SKUs; request an RFQ for custom builds.

Technical Specifications
| Cutter Type | Semi-chisel, Low profile |
|---|---|
| Kerf Width | .043" (narrow kerf) |
| Pitch | .325", 3/8" LP (standard catalog) |
| Gauge | .043" (catalog) |
| Material | 65Mn carbon steel (same grade as listed Series E MDMs) |
Any bench-reported power draw, runtime, or kerf deltas depend on test standard, baseline loop part number, ambient temperature/humidity, wood species/fixture, and saw electronics. We provide comparison disclosure tied to a declared baseline PN on request.

W-Series · Built for Boreal
Series W: Cold-Weather Chainsaw Chains
Standard catalog Series W uses 68CrNiMo alloy steel with specialized nitriding. All listed MDMs are semi-chisel full chain in .325" / 3/8" pitch with .050" or .058" gauge—see the product catalog for drive links. Low-temperature Charpy and operating-range statements are tied to batch qualification for those MDMs, not every chain in the industry.
