OD Scarfing Insert – H-HR
H-HR scarfing inserts are high-performance carbide tools used in tube and pipe mills to remove weld beads, especially suited for high-frequency welded (HFW) pipes. They are designed for precision, durability, and compatibility with various scarfing systems.
- Material: Made from tungsten carbide, often with CVD coatings to enhance wear resistance and cutting edge stability.
- Design: These inserts typically feature a custom radius (e.g., R35, R50, R75, R100) to match the curvature of the pipe being processed.
- Application:
- Used in external and internal weld bead removal
- Installed in scarfing rings or tool holders on tube mill lines
- Ideal for steel, stainless steel, and alloy tubes
