Description
Product Information
High-Performance Carbide Grooving Insert (MGMN/MRMN Series Type) This high-precision grooving insert is engineered from premium sub-micrograin carbide, specifically designed for parting, grooving, and profiling operations. The golden PVD/CVD coating (typically TiN or AlTiN) provides an exceptional thermal barrier, allowing for higher cutting speeds while extending tool life by resisting wear and heat. Its specialized chip-breaker geometry ensures superior chip control, preventing clogging and sudden fractures during continuous machining.
-
Primary Function: Precision external/internal grooving and parting-off.
-
Material Compatibility: Optimized for Steel (P), Stainless Steel (M), Cast Iron (K), and High-Temperature Alloys (S).
-
Design Advantage: Double-ended design offers exceptional economy, effectively doubling the tool life per insert.
