Kennametal 7061091 Hngj Hexagon Milling Insert Solid Carbide

Product Description

The KENNAMETAL 7061091 is a solid carbide milling insert in the HNGJ series, designed for high-performance face and shoulder milling operations. This hexagon-shaped, double-sided insert carries 12 usable cutting edges, making it an efficient choice for production environments where tooling cost-per-edge matters. The KCPM40 grade substrate is finished with a dual-layer TiAlN and AlCrN PVD coating applied via physical vapor deposition, delivering hardness and oxidation resistance at elevated cutting temperatures. The insert seats with a positive rake geometry and a honed cutting edge style for controlled chip formation in demanding material applications.

This insert is engineered for milling steel, stainless steel, superalloys, and titanium — workpiece material codes P, M, and S in the ISO classification system. It is compatible with the Kennametal Dodeka cutter series and is identified by ANSI code HNGJ535ANERGP and ISO code HNGJ0905ANERGP. The GP chip breaker geometry supports controlled chip evacuation across a range of feed rates. Right-hand cutting orientation. This insert is typically installed by CNC machinists and toolroom technicians in production or job-shop milling applications.

Key Features

• 12 cutting edges per insert — double-sided hexagon design maximizes edge utilization
• Solid carbide KCPM40 grade with TiAlN and AlCrN PVD dual-layer coating for heat and wear resistance
• Positive rake with honed cutting edge for clean entry into steel, stainless, and superalloy workpieces
• GP chip breaker geometry for reliable chip control across varied feed conditions
• Maximum depth of cut 0.177 inches; corner radius 0.047 inches (3/64 inch)
• Screw-lock insert holding method for secure, repeatable seating in the cutter body

Compatibility

Compatible with the Kennametal Dodeka cutter series. ANSI code HNGJ535ANERGP; ISO code HNGJ0905ANERGP. Designed for use in right-hand milling applications on steel, stainless steel, superalloys, and titanium workpiece materials.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Power down and lock out the spindle before indexing or replacing inserts. Use the manufacturer-specified torque wrench for the clamping screw to ensure consistent seating — refer to the Kennametal Dodeka cutter body documentation for torque specifications. Inspect the insert pocket and seating surface for chips or debris before installing a fresh edge to prevent insert rocking or premature failure.
