Kennametal 4175862 Grooving Insert NG2125 KCU10 Carbide Altin

Product Description

The KENNAMETAL 4175862 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. The insert carries a KCU10 grade with an AlTiN coating applied via PVD process, delivering heat resistance and extended tool life in demanding cutting conditions. It features a 3.18 mm cutting width and a maximum depth of cut of 2.79 mm, with a right-hand orientation. The NG-style insert is held in place by a clamp-type toolholder. Machinists and CNC operators running medium to hard workpiece materials will find the C3 and C4 material grade ratings appropriate for a wide range of steel and cast iron applications.

This insert is suited for external grooving, recessing, and light parting operations on turning equipment. The Top Notch series is a well-established platform used in production and job-shop environments where repeatable insert indexing and secure clamping are priorities. The NG2125 sizing and right-hand designation make it compatible with corresponding Top Notch series toolholders accepting that insert profile. The 55-degree included angle and 0.19 mm corner radius support controlled chip formation and surface finish in finishing and semi-finishing passes.

Key Features

• Solid carbide construction with KCU10 grade for wear resistance in steel and cast iron
• AlTiN coating via PVD process for elevated heat resistance and extended edge life
• 3.18 mm cutting width with maximum depth of cut of 2.79 mm
• Right-hand insert orientation, NG insert style
• 0.19 mm corner radius and 55-degree included angle for controlled chip geometry
• Clamp-style holding method for rigid, repeatable seating in Top Notch toolholders

Compatibility

Designed for use with Top Notch series clamp-style grooving toolholders that accept the NG2125 insert profile. The MSC and manufacturer cross-reference number for this insert is NG2125R/L.

Installation Notes

Insert installation and indexing should be performed with the machine fully powered down and spindle locked. Use the correct clamp screw torque as specified by the toolholder manufacturer for the Top Notch platform. Inspect the toolholder seat and clamp for debris or wear before seating a new insert. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
