Kennametal TNMG542MS KCU25 – Turning Carbide Insert

The Kennametal TNMG542MS turning carbide insert, featuring a KCU25 grade and TiN coating, excels in finish machining operations on titanium and non-ferrous workpieces, its neutral geometry and 60-degree triangle shape allowing for precise control and excellent surface finishes. With a 0.0313″ corner radius and 0.6250″ inscribed circle, this insert is well-suited for delicate turning applications where edge integrity and minimal tool pressure are crucial. Its AlTiN finish, paired with the KCU25 carbide substrate, provides a strong balance between wear resistance and toughness, making it an ideal choice for machining demanding materials like titanium.

What machinists are saying about TNMG542MS: Application: The KCU25™ grade is ideal for general machining of most steels, stainless steels, high-temp alloys, titanium, irons, and non-ferrous materials in a wide range of speeds and feeds with improved edge toughness for interrupted cuts and high feed rates. Turning Insert: TNMG542MS KCU25, Carbide AlTiN Finish, Neutral, 1.0820" Long, 0.6250" Inscribed Circle, 0.0

Grade KCU25 Characteristics

Kennametal KCU25 uses TiN coating tuned for finish machining on titanium, non-ferrous. The chemistry favors edge stability under interrupted cutting and resists thermal cracking on longer passes.

Features & Benefits

100% Genuine Kennametal – Original product with full quality guarantee, traceable batch.
Thermal Resistance – tin layer holds hardness above typical cutting-zone temperatures.
Edge Stability – Substrate chemistry tuned to limit micro-chipping on titanium, non-ferrous interruptions.
Professional CNC Tooling – Compatible with major CNC machine brands (Mazak, DMG, Haas, Doosan).
Ready Stock – In-stock for same-day dispatch from our CNC tooling warehouse.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finish Machining of titanium, non-ferrous in production CNC lines
Holds dimensional tolerance over multiple indexings (insert)
Designed for shop conditions typical of Kennametal tooling users worldwide
Pairs well with through-coolant setups for chip evacuation

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Mid-tier pricing reflects Kennametal’s production-grade tolerances rather than economy substrate.

Note: Compatible tool holders sold separately. Please confirm insert-holder seat compatibility (e.g. ISO seat designation) before ordering.
