Iscar 5697558 Milling Insert Ofmt 07T3-AER-76 IC928 Carbide

Product Description

The ISCAR 5697558 is a solid carbide milling insert carrying the ANSI designation OFMT 07T3-AER-76 IC928, designed for use in high-productivity face and helical milling operations. Part of the HELIOCTO series, this single-sided, octagonal insert features a TiAlN coating applied by PVD process using the IC928 grade, delivering strong performance in steel, stainless steel, superalloys, and titanium applications. The insert measures 0.7008 inches in inscribed circle diameter and 0.1790 inches thick, with a positive rake geometry and T-Land cutting edge style that promotes clean chip formation and extended tool life. Eight available cutting edges per insert reduce per-edge tooling cost in production environments.

This insert is suited for milling operations on steel (ISO P), stainless steel (ISO M), and superalloys and titanium (ISO S) workpieces in both roughing and semi-finishing contexts. The neutral hand orientation and screw-holding method make it compatible with standard HELIOCTO toolholders using the HOF-07 cutter series. It is used in job shop and production machining environments where consistent edge performance on difficult materials is required. The IC928 grade and PVD TiAlN coating are particularly well matched to interrupted cuts and conditions where thermal resistance is a priority.

Key Features

• Octagonal insert shape with 8 cutting edges per insert for maximum edge utilization
• IC928 grade PVD TiAlN coating for thermal resistance and wear performance on steel and superalloys
• Positive rake with T-Land cutting edge style for reduced cutting forces and controlled chip flow
• Maximum depth of cut of 0.1340 inches (3.40 mm) per pass
• Corner radius of 0.0236 inches (0.60 mm) for controlled surface finish at the cutting edge
• Neutral hand orientation for flexible cutter body compatibility
• Conforms to ANSI and ISO 13399 standards

Compatibility

Designed for use with ISCAR HELIOCTO series cutter bodies in the HOF-07 cutter series. Insert size code 07T3. Compatible with toolholders using screw-type insert clamping.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the cutter body manufacturer's torque specifications for the clamping screw. Inspect the insert pocket seat and clamping screw for wear or debris before seating a new insert. Use the correct Torx or hex key as specified by the toolholder documentation. Never operate the cutter above the maximum depth of cut or feed rate specified in the ISCAR HELIOCTO tooling catalog for this insert geometry.
