[PRECISION SPECS & PRO MAINTENANCE] This high-performance chain is engineered for 16-inch guide bars with a 3/8" Low Profile (LP) Pitch, .050" (1.3mm) Gauge, and 57 Drive Links. Due to the extreme hardness of the cutters, maintenance requires a 5/32" (4.0mm) Diamond Coated Sharpener. Standard steel files will not effectively sharpen carbide material. Please verify your drive link count to ensure a precise fit for your 16" bar. [PATENTED BUILD & SUPERIOR DURABILITY] Utilizing our patented carbide-tipping technology and Japanese chrome-plated leads, these cutters stay sharp up to 10 times longer than standard steel chains. Our precision-brazed carbide tips and hardened rivets ensure robust link connections and stable cutting performance under high-load conditions, offering a significant economic advantage by reducing chain replacement costs. [ADVANCED PERFORMANCE IN HARSH CONDITIONS] Specifically designed to tackle the most demanding environments, this chain excels at cutting through "dirty" wood, sand-caked logs, and frozen hardwoods. The engineered low-kickback geometry provides a smoother, more controlled cutting action with minimal feedback, making it the ideal choice for professional arborists and heavy-duty land clearing where standard chains fail. [EXTENSIVE MODEL COMPATIBILITY] A precision replacement for popular saws, including Echo CS-310, CS-352, CS-370, and CS-400 (when used with Echo branded bars). It also fits Worx WG300, WG303, WG304, Sun Joe SWJ699E, and Remington RM4216. For a comprehensive list of all compatible Hitachi, Shindaiwa, and Milwaukee models, please refer to the compatibility chart in the A+ content below. [SAFETY USAGE & MATERIAL LIMITATIONS] IMPORTANT: This chain is strictly intended for WOOD CUTTING ONLY. While tungsten carbide is incredibly hard, its brittle nature makes it susceptible to damage from metal impact. Avoid contact with nails, wire, fencing, or stones, as hitting these objects may cause the carbide tips to chip or shatter. Adhering to these guidelines ensures maximum safety and tool longevity. Professional Grade Byane Carbide Chainsaw Chain: The Ultimate Solution for Tough Timber When your work takes you into abrasive environments—cutting through mud-caked logs, stumps, or frozen hardwood—standard steel chains lose their edge in minutes. The Byane Carbide series is engineered to stay in the wood longer. Using patented precision-brazing technology, we bond high-hardness carbide cutter heads to a Japanese chrome-plated chassis, creating a tool that outlasts traditional chains by up to 12 to 1 in abrasive conditions. Technical Specifications: Chain Type: Carbide Tipped (Low Kickback / ANSI Compliant) Bar Length: 16 Inches Pitch: 3/8" Low Profile (LP) Gauge: .050" (1.3mm) Drive Link Count: 57 Recommended File: 5/32" (4.0mm) Diamond Coated Sharpener Comprehensive Compatibility List: This 57-drive link chain is designed to fit the following models (3/8" LP Pitch .050" Gauge setups): Echo: CS-300, CS-310, CS-330T, CS-341, CS-346, CS-352, CS-355T, CS-370, CS-400 (Note: Use with Echo branded bars). Worx: WG300, WG303, WG303.1, WG304. Sun Joe: SWJ699E. Remington: RM4216. Shindaiwa: 300, 345, 350, 357, 104P. Homelite: UT10532. Cross-Reference: Replaces Oregon S57. Maintenance Note: To retain the superior edge of the carbide cutters, regular sharpening should only be performed with a diamond-surfaced tool (5/32" / 4.0mm). Standard abrasive stones or files are ineffective against our patented carbide cutters.
