Kennametal 5653137 Milling Insert Sdht X500 Solid Carbide

Product Description

The KENNAMETAL 5653137 is a solid carbide milling insert in the SDHT series, designed for demanding milling operations where edge wear and thermal load are primary concerns. It features a square insert shape with a 15-degree relief angle and carries a tri-layer CVD coating of TiN, TiC, and TiN in the X500 grade. The inscribed circle measures 0.5 inches, and the insert thickness is 3/16 inches (0.187 inches). The chip breaker designation is 423, optimized for controlled chip formation. This insert is installed by machining professionals in production and job-shop environments.

This insert is suited for milling applications where solid carbide substrate and CVD coating provide thermal and abrasion resistance. The SDHT series geometry and 15-degree relief angle make it appropriate for a range of milling operations including face milling and shoulder milling. It is sold individually with a minimum order quantity of 5 units per purchase. The insert size code is 120412, and the UNSPSC code is 23291601, consistent with standard indexable milling insert classifications used in industrial procurement.
