Kennametal 4175850 Grooving Insert KCU10 Carbide Altin

Product Description

The KENNAMETAL 4175850 is a solid carbide grooving insert in the Top Notch series, designed for precision external grooving and parting operations on CNC lathes and turning centers. The insert carries a KCU10 manufacturer grade with a PVD-applied AlTiN coating, delivering thermal resistance and wear life on a wide range of workpiece materials. It features a 1.19 mm cutting width, a maximum depth of cut of 1.27 mm, and a corner radius of 0.09 mm, making it suited for fine, close-tolerance groove profiles. The clamp-style insert holding method provides rigid, repeatable seating. This insert is intended for use by machinists and CNC lathe operators working in production or job-shop environments.

The 4175850 targets metal-cutting applications where tight groove geometry and consistent tool life are required. Its right-hand orientation suits standard front-tool-post setups on conventional and CNC turning equipment. The NG insert style and 2047 insert size follow the Top Notch platform convention, making this insert compatible with Top Notch toolholders that accept the NG2047 seat. The metric measurement type designation and 5.56 mm cutting height support metric-dimensioned tooling programs. Typical applications include OD grooving, face grooving lead-ins, and part-off operations on steel, stainless, and cast-iron workpieces where AlTiN coating performance is specified.

Key Features

• Solid carbide substrate with KCU10 grade for toughness and wear resistance
• PVD AlTiN coating for elevated-temperature and abrasion resistance
• 1.19 mm cutting width for precise, narrow groove profiles
• 1.27 mm maximum depth of cut with a 0.09 mm corner radius for controlled groove geometry
• Right-hand insert orientation for standard lathe toolpost configurations
• Clamp-style holding method for rigid, repeatable insert seating

Compatibility

Designed for use with Top Notch series toolholders accepting the NG2047 insert seat. The MSC/Manufacturer Number reference is NG2047R/L. Confirm toolholder seat geometry and clamp compatibility before installation.

Installation Notes

Insert replacement on turning toolholders should be performed with the machine powered off and the spindle fully locked. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and can crack under excess clamp load. Inspect the insert pocket and clamp for chips or debris before seating the new insert. Qualified machinists or tooling technicians should verify offset and geometry compensation in the CNC control before resuming cuts.
