Kennametal 3330952 Milling Insert HNGJ0905ANENLD KCK15

Product Description

The KENNAMETAL 3330952 is a solid carbide hexagon milling insert designed for high-productivity face and shoulder milling in cast iron applications. Carrying the ISO/ANSI designation HNGJ0905ANENLD and manufactured to grade KCK15, this insert features a multilayer CVD coating of TiN, TiCN, and Al2O3 applied via MTCVD process. The hexagonal geometry delivers 12 usable cutting edges per insert, lowering cost per edge on high-volume production runs. A negative rake angle and honed cutting edge combine to provide controlled chip formation and edge stability when cutting abrasive cast iron. Licensed HVAC and machining professionals will recognize this insert as part of the Kennametal Dodeka cutter series.

This insert is suited for milling cast iron workpieces in production machining environments, including automotive, heavy equipment, and general manufacturing applications. It is compatible with the Kennametal Dodeka cutter series, which accepts screw-held double-sided hexagon inserts of this style. The HNGJ0905ANENLD designation conforms to both ANSI and ISO standards, making it straightforward to cross-reference against existing tooling programs. The neutral hand orientation allows flexible positioning within compatible cutter bodies.

Key Features

• 12 cutting edges per insert - double-sided hexagon design maximizes tool life per insert
• KCK15 grade with TiN, TiCN, and Al2O3 multilayer CVD (MTCVD) coating for wear resistance in cast iron
• 0.0470 inch (1.20 mm) corner radius for controlled edge engagement
• Negative rake angle with honed cutting edge for edge stability and reduced chipping
• Screw-held insert mounting for positive, repeatable seating in the cutter body
• Conforms to ANSI and ISO standards - ANSI code HNGJ535ANENLD, ISO code HNGJ0905ANENLD

Compatibility

Designed for use in the Kennametal Dodeka cutter series. Compatible with cutter bodies accepting HNGJ-style screw-held hexagon inserts with a 0.6250 inch inscribed circle diameter.

Installation Notes

Installation is performed by machining professionals during tooling setup on milling machines. Power down and lock out the spindle before replacing inserts. Use the manufacturer-specified torx or hex key to seat the clamping screw - do not overtighten, as this can crack the carbide body. Inspect the insert pocket for debris or wear before seating a new insert to ensure proper contact and runout.
