Kennametal 3858116 Milling Insert EDPT180508PDSRGE KC725M

Product Description

The KENNAMETAL 3858116 is a solid carbide milling insert in the EDPT series, designed for high-performance face and shoulder milling applications. Manufactured to ISO code EDPT180508PDSRGE and ANSI code EP1808SGE, this insert features a TiAlN coating applied via PVD process, delivering strong oxidation resistance and wear performance at elevated cutting temperatures. The parallelogram insert geometry with a positive rake angle and right-hand cutting orientation promotes efficient chip flow and reduced cutting forces. Corner radius measures 0.0313 inches (1/32 inch) with a chamfered and honed cutting edge style. Two cutting edges per insert are available. Installation is performed by licensed machinists and CNC tooling technicians in production and job shop environments.

This insert is suited for milling steel, stainless steel, superalloys, and titanium workpieces, covering material grade classifications C5, C6, and C7 with primary workpiece material codes P, M, and S. It is designed for use in face milling, shoulder milling, and high-feed applications where positive-geometry inserts with PVD coatings are specified. The GE chip breaker geometry is optimized for controlled chip formation across these demanding material groups. Compatible with KENNAMETAL Mill 1-18 cutter bodies per the Mill 1-18 cutter series designation.

Key Features

• TiAlN PVD coating for heat resistance and extended tool life in steel and superalloy machining
• Positive rake geometry with chamfered and honed cutting edges reduces cutting forces
• Right-hand, single-sided parallelogram insert with 70-degree included angle
• GE chip breaker for reliable chip control across steel, stainless steel, and titanium
• Screw-held insert mounting for secure, repeatable seating in compatible toolholders
• Meets ANSI and ISO dimensional standards for verified fitment

Compatibility

Designed for use with KENNAMETAL Mill 1-18 cutter series bodies. Conforms to ISO code EDPT180508PDSRGE and ANSI code EP1808SGE for cross-reference fitment verification.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the manufacturer-specified torx or hex key to drive the clamping screw to proper engagement without overtightening, which can crack the carbide body. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert.
