Overview

The STIHL 25″ (63 cm) Chainsaw Guide Bar (3/8″ Pitch, 1.6 mm / 0.063″ Gauge) is a professional-grade replacement cutting attachment designed for high-performance STIHL mid-to-large capacity chainsaws. Built from solid, high-grade steel with induction-hardened rails, this guide bar provides exceptional stiffness, precise chain tracking, and long operational life under demanding forestry and bucking conditions.

Featuring a 3/8″ pitch and 1.6 mm (0.063″) drive link gauge, this bar is optimized for smooth power transfer and efficient sawdust clearance. It incorporates STIHL’s integrated Ematic lubrication system, which directs chain oil straight to the bar rails and saw chain drive links to reduce friction oil consumption by up to 50%. Ideal for logging, timber cutting, and heavy farm firewood prep, it ensures structural stability and reduced kickback risk during continuous heavy-duty cutting operations.

Key Features & Benefits

• Solid Steel Construction: Manufactured from high-strength wear-resistant steel to resist flexing and rail spreading under heavy loads.

• Ematic Lubrication System: Directs chain lubricant directly to the chain drive links, reducing oil consumption and thermal wear.

• Induction-Hardened Track Rails: Provides maximum wear resistance along the top and bottom edges where chain friction is highest.

• Precision Nose Sprocket: Fully sealed nose sprocket bearing reduces rotational friction and prolongs tip life during plunge cuts.

• Professional Cut Length: 25-inch (63 cm) active cutting length handles large-diameter trunks and hardwood timber efficiently.
