Kennametal NGD2M250RK Carbide Grooving Insert with 2.5 mm Cutting Width Right-Hand Orientation and PVD Coated Grades for CNC Lathes

The KENNAMETAL NGD2M250RK is a right-hand, single-edge carbide grooving & turning insert from the Top Notch™ NGD-K series, designed for 2.5 mm width grooving, parting, and profiling on CNC lathes. It features a size 2 insert body, K-style chipbreaker, and is available in KCU10/KC5025 PVD-coated grades, delivering precise dimensional control, excellent surface finish, and reliable chip evacuation in steels, stainless steels, and cast iron. Ideal for general-purpose to medium-duty grooving in automotive, hydraulic, and general engineering components.

• Top Notch™ NGD-K Series: Dedicated for grooving, turning, and deep grooving with optimized chip control.
• 2.5 mm Cutting Width (W): Precision-ground for standard 2.5 mm grooves, parting, and profiles.
• Size 2 Insert: Compact, rigid design for stable clamping in compatible Kennametal tool holders.
• Right-Hand (RK) Orientation: Single right-hand cutting edge for external grooving/turning.
• K-Style Chipbreaker: Standard chip control geometry for smooth, consistent chip flow.
• PVD Coated Grades: KCU10 (AlTiN) or KC5025 (TiAlN) for high wear resistance and edge stability.
• High Precision: Sintered carbide substrate with tight tolerances for accurate groove dimensions.

• Carbon steels (1045, S355, Q235)
• Alloy steels (4140, 42CrMo4, HRC <48)
• Stainless steels (304, 316, 420, duplex)
• Cast iron (HT200, HT250, ductile iron)
• Non-ferrous metals (aluminum, brass, light cuts)

• External grooving & parting (2.5 mm width)
• Groove turning, profiling, and undercutting
• Medium-duty CNC lathe operations (continuous cuts)
• Hydraulic components, fasteners, automotive parts
• General-purpose grooving in mass production

As a versatile 2.5 mm grooving insert, it combines rigid size 2 design, reliable K-chipbreaker, and high-performance PVD grades for consistent results in diverse materials. Kennametal’s precision manufacturing ensures minimal runout, accurate groove profiles, and long tool life in medium-duty grooving applications.
