33RSK 72E CHAIN LOOP

Overview

The STIHL 33RSK 72E Chain Loop (38740050072) is designed for high-efficiency chainsaw cutting applications requiring fast material removal and clean cuts in hard or frozen wood.

Technical Features

• Full-chisel, razor-edged square-cornered cutter geometry: Minimizes chain friction for a smooth, clean cut in hard or frozen wood applications.
• Klassic-designation cutter geometry: Provides excellent control characteristics and very good chip flow, enhancing overall cutting efficiency during operation.
• Engineered cutter and tie strap design: Reduces vibration levels significantly, lowering operator fatigue during extended use while retaining aggressive cutting performance.
• Full-chisel cutter profile: Delivers fast material removal rates, making the RSK series faster-cutting than STIHL RM chain under comparable conditions.
• Optimized plunge-cutting geometry: Supports both standard cross-cutting and plunge-cutting techniques, expanding application versatility on the job site.

Applications

• Cross-cutting and bucking of hard or frozen timber where clean, low-friction cuts are required.
• Plunge-cutting operations demanding precise entry and efficient chip evacuation.
• Professional and demanding cutting tasks where cutting speed is prioritized over low-maintenance requirements.

Note: RSK chain requires careful sharpening and consistent maintenance to sustain peak cutting performance. Regular inspection of cutter geometry is recommended to preserve the full-chisel edge and ensure continued efficiency.
