Tsumura Chainsaw Bar - 24", 3/8", .063", Premium Hard Tip, D025

Product Overview

The Tsumura 248HT4 (24-31-063-PH) is the professional's choice for a Solid Hard Tip (Stellite-tipped) bar in Australia. Unlike sprocket-nose bars, this is one solid piece of SKS-51 Japanese steel with no moving parts in the nose.

This bar is engineered for "Armor Tip" performance—it is virtually indestructible in gritty, sandy, or fire-salvaged timber where a sprocket bearing would instantly seize. It is the industrial standard for large-displacement Stihl powerheads used in heavy-duty fencing, stumping, and dirty wood cutting.

Why Choose Tsumura Hard Tip Bars?

• Armor Tip Durability: The Stellite™ nose inlay is exceptionally thick and laser-welded, ensuring the rails stay true even when cutting "dirty" timber that would destroy a sprocket nose.
• Versatile Pitching: Because there is no sprocket, the bar is pitch-neutral. You can swap between 3/8" and .404" loops by only changing your drive sprocket.

Rigid One-Piece Steel: Induction-hardened rails prevent "mushrooming" and rail-spread, making it the most durable 24" bar option for high-torque saws like the MS 500i.
