SKU = 16-42-K367-PS, 163PV2

Product Overview

The Tsumura 163PV2 is a professional-grade, solid steel chainsaw bar manufactured in Japan. Unlike laminated bars, this "Premium" series bar is CNC-milled from a single piece of high-carbon SKS-51 tool steel. It features a replaceable sprocket nose (Premium Tip) specifically designed for .325" pitch chain.

This bar utilizes the D025 (Stihl Medium/Large) mount and is the preferred choice for professional users who want the smooth, fast-cutting characteristics of a .325" system on mid-to-high displacement Stihl powerheads.

Why Choose Tsumura Premium Bars?

• Solid Steel Rigidity: Superior to laminated bars for staying straight in the cut, especially when bucking dense hardwoods.
• Induction Hardened Rails: Tsumura's rails are significantly harder than standard bars, resisting "rail spread" and mushrooming.

Efficient Lubrication: CNC-machined oil reservoirs ensure constant lubrication to the .325" chain chassis, reducing heat build-up.

Chainsaw Bar | Tsumura Light and Tough | Professional
Performance

Premium Japanese-Crafted Chainsaw Bar for Professional Durability
Experience exceptional strength and precision with the Tsumura Light and Tough Chainsaw
Bar - crafted in Japan using advanced manufacturing techniques and premium materials.
This professional-grade guide bar delivers the perfect balance of durability and performance that serious professionals demand for challenging cutting tasks.

Superior Japanese Engineering & Craftsmanship

What sets Tsumura bars apart is the proprietary salt bath heat treatment process that
achieves an ideal balance of toughness and hardness in the steel. Unlike conventional
methods that heat steel rapidly to over 800°C, Tsumura's gradual heating approach creates a superior steel structure that maintains its integrity even under extreme conditions. The result is a bar that resists bending, warping, and rail spreading significantly better than standard bars, delivering longer service life and more precise cutting performance.

Professional-Grade Features That Make the Difference
Premium SKS-51 Steel Construction: One-piece solid high-carbon steel provides
exceptional strength and durability for demanding professional use
Proprietary Salt Bath Heat Treatment: Creates the perfect balance of hardness and
toughness for superior wear resistance and longevity
Precision Laser-Cut Manufacturing: Ensures exact specifications and consistent rail
dimensions for smoother chain operation
Replaceable Sprocket Nose with Grease Point: Extends bar life by allowing replacement
of the most wear-prone component and proper bearing lubrication
Optimized Oil Flow Design: Ensures proper lubrication throughout the bar to reduce
friction and heat buildup
Reduced Vibration Technology: Engineered for smoother operation and improved
control during cutting

The Professional's Choice for Demanding Applications
There's a reason Tsumura remains the preferred choice for professionals using high-powered
chainsaws in demanding environments. When your livelihood depends on your equipment,
you can't afford downtime or inconsistent performance. The exceptional durability and
cutting precision of Tsumura Light and Tough bars translate to more productive cutting time,
reduced maintenance, and lower long-term costs - critical advantages for professional
loggers, arborists, and forestry workers.
