Description
Overview:
This Test Flange is a genuine Stihl part for the TS410 and TS420 cut-off/disc cutters. It is a precision‐made metal flange that locates and clamps the cutting disc securely on the machine's spindle, helping to maintain balance, reduce run‐out, and support safe, efficient cutting. Built for the harsh conditions found on site and in workshops, it offers a snug, reliable fit with the existing spindle hardware and locking nut. By keeping the disc seated firmly and evenly, it helps the machine deliver consistent performance and prolongs disc life. As an OEM component, it matches the original specification for fit and function, making it a straightforward replacement for worn or damaged flanges on Stihl TS410 or TS420 machines.
Key Features:
- Genuine Stihl OEM part for assured compatibility and performance (OEM ref: 4238 890 1200)
- Accurate fit for TS410 and TS420 to maintain disc stability and alignment
- Durable metal construction with a clean, machined face for reliable clamping
- Helps reduce vibration and disc slip by keeping the disc concentric to the spindle
- Supports safe operation by maintaining a secure disc connection at working speeds
- Resists wear in dusty, wet, and abrasive environments typical of cutting work
- Easy to install as a direct replacement using basic hand tools
- Works with standard abrasive or diamond discs used on these models and with the original outer flange and nut
Typical Applications:
Used during routine maintenance or repair of Stihl TS410/TS420 cutters when the existing flange is worn, burred, or damaged. Suitable for general cutting of concrete, masonry, asphalt, stone, and metal using compatible discs, where secure disc mounting and reliable alignment are needed for consistent, safe operation.
