SEMT-13T3-ACP300 is an industry-standard, indexable carbide milling insert engineered and manufactured by Sumitomo Electric Hardmetal. It belongs to the Indexable Milling Inserts product category and is primarily deployed in high-efficiency face milling cutter bodies like the Sumitomo SEC-Wave Mill WGX series.
- S: Square geometry providing four highly economical 45-degree cutting edges.
- E: Positive flank profile with a 20-degree clearance angle to prevent catastrophic heel rubbing.
- M: Precision standard tolerance class regulating edge-height positioning uniformity.
- T: Single-sided insert face containing a countersunk screw hole for maximum pocket clamping stability.
- 13: Nominal cutting edge length of 13.4 mm.
- T3: Standard structural insert thickness of 3.97 mm.
- ACP300: Sumitomo’s premium tough-matrix PVD coated grade. It incorporates nanometer-thin multi-layered TiAlN coatings over a highly impact-resistant substrate, optimized to withstand heavy interrupted cuts and scale surfaces across carbon steels, alloy steels, and stainless steels.
