Tsumura, Stihl Lightweight Chainsaw Bar 208PK5 - 20", .404", .063" , D025, 3003 000 9721, 30030009721

Tsumura Lightweight Chainsaw Bar - 20", .404", .063", D025

Product Overview

The Tsumura 208PK5 is a professional-grade "Light & Tough" chainsaw bar manufactured in Japan. This specific model is a specialist configuration engineered for high-displacement Stihl saws running .404" pitch chain. It features Tsumura’s signature weight-reduction technology: staggered dove-tailed notches are laser-cut into the SKS-51 steel body and filled with a specialized hard resin, reducing total weight by approximately 20%.

This bar provides the aggressive cutting power and durability of a .404" system while significantly improving the balance and handling of large powerheads like the MS 661 or MS 500i.

Fitment Guide

• Specialist Note: This is the ultimate "short" heavy-duty bar for MS 661 users who want the stump-pulling power of .404" chain in a lightweight, 20-inch package for better maneuverability.

Why Choose Tsumura Lightweight Bars?

• 20% Weight Reduction: The resin-filled inserts move the center of gravity back toward the saw handle, making large, heavy saws feel significantly more agile and easier to control.
• Industrial Grade .404" Tip: Unlike smaller bars, this nose is specifically built to handle the higher vibration and impact loads of .404" cutters, featuring premium Japanese bearings.
• SKS-51 Tool Steel: Milled from high-carbon Japanese steel with induction-hardened rails that resist "mushrooming" and wear even when cutting Australia's hardest timbers.
