Kennametal VNMG160404 MS Chipbreaker 35° Negative Rhombus KCS10B Ultra-Fine Grain Carbide Turning Insert for Superalloys

VNMG160404MS KCS10B is authentic American Kennametal Kenloc series 35° negative rhombus PVD coated carbide turning insert, specially engineered for precision finishing and medium stock removal turning of nickel-based, cobalt-based and iron-based high-temperature superalloys, suitable for composite external OD turning, internal deep hole boring and end face turning operations. Equipped with MS superalloy dedicated medium chipbreaker and tiny 0.4mm finishing nose radius, each double-sided diamond insert provides four independent reusable cutting edges to significantly reduce per-unit tool consumption cost. Adopting KCS10B ultra-fine grain High-PIMS AlTiN coated carbide substrate, it perfectly matches MVJNR/MVJNL series Kenloc lever-lock negative turning tool holders. The unique 35° diamond geometry delivers outstanding accessibility for narrow deep small-diameter internal boring and complex superalloy component contour profiling, while the MS positive rake chipbreaker minimizes cutting load and thin-wall superalloy workpiece elastic deformation. Suitable for stable continuous precision turning and mild interrupted machining of uneven forged superalloy blanks. Widely applied on precision CNC turning lathes for aerospace turbine blades, aircraft engine superalloy shafts, energy power plant high-temperature valve components and superalloy precision fitting mass turning production lines.

• Unique 35° negative rhombus insert geometry, superior reachability for narrow deep small-diameter internal boring and complex curved superalloy component contour profiling, processing range unreachable by standard 80° square inserts
• Exclusive MS medium universal chipbreaker with optimized positive rake face, specially tuned for high ductility superalloy materials; forms short, controllable curled chips to eliminate chip winding and scratch damage to high-precision machined surfaces
• KCS10B grade adopts proprietary High-PIMS coating technology, produces ultra-smooth uniform AlTiN coating film with ultra-high adhesion strength on sharp cutting edges; drastically improves resistance to depth-of-cut notching and crater wear, the primary failure risks of superalloy turning
• Ultra-fine gradient grain WC-Co carbide substrate with balanced hardness and impact toughness, prevents cutting edge micro chipping and catastrophic breakage under mild interrupted cutting of uneven forged superalloy blanks
• Low-friction smooth AlTiN coating surface, outstanding anti-adhesion performance, effectively suppresses built-up edge (BUE) formation on sticky nickel/cobalt superalloys, ensures consistent dimensional tolerance and mirror-grade workpiece surface finish
• Double-sided negative rake insert design with four independent usable cutting edges, excellent cost efficiency for long-cycle continuous superalloy mass production workshops
• Standard central clamping hole for Kenloc lever-lock tool holders, stable clamping rigidity under static heavy cutting load, minimizes tool vibration during low-speed high-hardness superalloy turning
• Multi-operation universal adaptability: supports external OD turning, end face facing and internal ID deep hole boring, simplifies aerospace workshop tool varieties and inventory procurement costs
