Kennametal 4175858 Grooving Insert KCU10 Solid Carbide Altin

Product Description

The KENNAMETAL 4175858 is a solid carbide grooving insert in the Top Notch series, designed for precision external grooving and cutoff operations on CNC lathes and turning centers. Manufactured in grade KCU10 with a PVD-applied AlTiN coating, this right-hand insert delivers a 2.39 mm cutting width and a maximum depth of cut of 2.79 mm. The AlTiN finish provides thermal resistance and wear protection, making it well suited for interrupted cuts and harder workpiece materials. Machinists and toolroom technicians working in production and job-shop environments will find this insert reliable for consistent groove geometry and extended tool life in demanding turning applications.

This insert is intended for use in Top Notch series toolholders that accept the NG2094 insert style with clamp-style holding. It is appropriate for metric-dimensioned setups targeting groove depths in the 2.00 mm to 3.00 mm range. The included 55-degree angle geometry and a 0.19 mm corner radius contribute to controlled chip formation and repeatable groove profiles. Typical applications include groove turning on steel, alloy steel, and similar materials in both production and maintenance machining environments. This insert ships individually and carries a minimum order quantity of 5 units.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing the insert. Ensure the clamp screw and insert pocket are free of chips and debris before securing the insert, as contamination can affect seating and groove accuracy. Follow the toolholder manufacturer's clamping torque guidelines and confirm insert orientation matches the programmed tool path before resuming operation.
