Indexable Inserts, Grade KCPM20

Kennametal has launched new BeyondTM Grade KCPM20TM Indexable Inserts from that excel in dry machining. Target is best in class for plain and alloyed steels, face, shoulder, and profile milling styles available. The company is introducing the new Beyond KCPM20 grade indexable milling insert, specially engineered for high-speed dry machining in light to medium milling of steel and stainless steel parts under stable conditions. KCPM20 is being recommended as an ideal optimisation grade for stainless steel machining applications where coolant is not used and excellent wear resistance is required. Each specific Beyond grade from Kennametal is optimised with substrate characteristics and coating thickness specific to its application. The result is productivity improvement and an expanded range of application for each new product compared to the original grade. All new Beyond inserts are CVD (chemical vapour deposition) coated, but whereas conventional CVD coatings are under tensile stress, Beyond inserts undergo a proprietary post-coat treatment on all surfaces to reduce this stress, which improves coating adhesion and reduces micro-chipping. More uniform and reliable wear of the cutting edge results in improved and more consistent tool life. Smoother surfaces also lower frictional forces, another factor that expands applications and permits higher cutting speeds. Additionally, all Beyond inserts are top- and bottom-ground after coating for a better seating surface in the toolholder, which improves security.
These inserts are available in a variety of Kennametal milling cutter styles, including:

• DodekaTM for face milling in stable applications
• KSOMTM, where lighter cutting forces are required
• Mill 1TM for high-performance shoulder milling
• KDMTM for general-purpose and die/mould machining.
