Iscar 3181028 Indexable Square-shoulder End Mill

Product Description

The ISCAR 3181028 is an indexable square-shoulder end mill from the Heliplus series, designed for precision milling operations in metalworking and machining environments. The tool features a 5/8 inch cutting diameter, a maximum depth of cut of 0.303 inches, and a 90-degree lead angle that produces true square shoulders in a single pass. With through-coolant capability, it supports aggressive material removal while managing heat at the cutting zone. Installation and setup are handled by machinists and CNC operators in production and job-shop environments. The HP E90AN-07 toolholder cutter style accepts HP AN.. 0702.. insert style inserts, which are secured via screw-type insert holding.

This end mill is suited for milling operations requiring square-shoulder profiles on ferrous and non-ferrous materials. The Heliplus series targets applications where consistent insert indexing and thermal control are priorities, such as aerospace component machining, mold work, and general production milling. The 3-flute, 3-insert configuration balances cutting forces and chip evacuation across a range of feed rates and depths of cut. The cylindrical shank allows direct mounting in standard ER or side-lock toolholders.

Key Features

• HP E90AN-07 cutter style designation for straightforward toolholder and insert selection
• Heliplus series construction meets AS 9100, ISO 9001:2008, ISO 14001:2004, ISO 50001, and OHSAS 18001:2007 standards
• Cylindrical shank for compatibility with standard toolholding systems

Compatibility

Designed for use with the HP E90AN-07 toolholder cutter style and HP AN.. 0702.. insert style inserts. Refer to ISCAR Heliplus series documentation to confirm insert grade and geometry selection for your specific workpiece material.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before mounting or removing the tool, ensure the machine spindle is fully stopped and the machine is in a safe state per shop lockout/tagout procedures. Verify toolholder runout and insert seating before cutting. Coolant supply lines should be confirmed open and at operating pressure before engaging through-coolant mode.
