Kennametal 4175907 Grooving Insert 1.5mm Top Notch KCU10

Product Description

The KENNAMETAL 4175907 is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. Manufactured to the Top Notch series standard, this insert features a 1.5 mm cutting width and a maximum depth of cut of 2.79 mm, making it suitable for shallow to mid-depth grooving applications. The KCU10 grade substrate is applied with an AlTiN coating via a PVD process, providing enhanced wear resistance and thermal stability at elevated cutting speeds. The insert uses a clamp-style holding method and is configured for right-hand cutting. Machinists and CNC operators working in production environments are the primary installers and users of this insert.

This insert is suited for use in metalworking applications across aerospace, automotive, and general manufacturing industries. The NR insert style with a full radius corner and 0.75 mm corner radius makes it well matched for grooving ductile and hard materials classified under material grades C3 and C4. It fits standard Top Notch series toolholders that accept NR2M075 inserts. The metric-measurement insert is sold individually per package, with a minimum order quantity of 5 pieces.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC setup technician with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and clamp hardware specified for Top Notch series toolholders when seating the insert. Inspect the insert pocket and clamp for wear or debris before installation. Never exceed the maximum depth of cut rating to avoid insert fracture or toolholder damage.
