Kennametal 3033731 Milling Insert EDPT140408PDERHD KCPK30

Product Description

The KENNAMETAL 3033731 is a solid carbide milling insert carrying ISO designation EDPT140408PDERHD and manufacturer grade KCPK30. It features a multilayer CVD coating of TiN, TiCN, and Al2O3 applied over a solid carbide substrate, delivering wear resistance across a range of workpiece materials. The insert measures 0.6878 inches in length and 0.3300 inches wide, with a thickness of 0.1770 inches. A 0.031-inch corner radius and honed cutting edge style reduce chipping risk on interrupted cuts. This is a single-sided, right-hand insert with a positive rake geometry and a 15-degree relief angle, held in place by a screw-mount system.

This insert is suited for milling operations on steel, stainless steel, cast iron, superalloys, and titanium, covering material application codes P, M, K, and S. It is compatible with the Kennametal Mill 1-14 cutter series and uses the HD chip breaker geometry, which is well matched to general-purpose face milling and shoulder milling in both roughing and semi-finishing applications. The insert fits standard EDPT-series toolholders and is commonly used in production machining environments where tool change frequency and insert consistency are priorities for machinists and CNC operators.

Key Features

• Multilayer CVD coating: TiN, TiCN, and Al2O3 for extended tool life on hard and abrasive workpiece materials
• KCPK30 grade solid carbide substrate rated for steel, stainless steel, cast iron, superalloys, and titanium
• HD chip breaker geometry suited for a broad range of milling depths and feed rates
• Positive rake, 15-degree relief angle reduces cutting forces on lighter machine tool setups
• Honed cutting edge style minimizes micro-chipping on entry and exit of interrupted cuts
• Screw-mount insert holding method for repeatable seating and easy indexing

Compatibility

Compatible with the Kennametal Mill 1-14 cutter series. Conforms to ANSI code EP1408EHD and ISO code EDPT140408PDERHD. Fits EDPT-series toolholders accepting a 0.1339-inch hole diameter screw mount.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver specified by the toolholder manufacturer when seating the clamping screw — do not over-torque, as this can crack the carbide substrate. Inspect the insert pocket seating surface for chips or debris before installing a new insert to ensure proper seating and runout control.
