Iscar 5601916 Milling Insert Ofmt 07T3-AER-76 IC28 Carbide

Product Description

The ISCAR 5601916 is a solid carbide milling insert carrying the ANSI designation OFMT 07T3-AER-76 IC28. It belongs to the HELIOCTO series and is designed for indexable milling operations targeting non-ferrous metals. The insert features an octagonal shape with 8 cutting edges, a positive rake geometry, and a T-Land cutting edge style that supports clean, efficient material removal. At 0.1790 inches thick with a 0.7008-inch inscribed circle diameter and a maximum depth of cut of 0.1340 inches, this insert is sized for the HOF-07 cutter series. The IC28 grade is an uncoated, bright-finish solid carbide grade suited to the demands of non-ferrous machining. Installation is performed by licensed or qualified machining professionals using the screw-holding method.

This insert is intended for milling applications involving non-ferrous metals, corresponding to ISO material code N. The HELIOCTO series application context targets high-feed and general milling where octagonal geometry maximizes available cutting edges per insert, reducing per-edge tooling cost. The neutral hand orientation allows flexible placement in compatible toolholders. The 76 chip breaker designation and 25-degree relief angle contribute to controlled chip evacuation and reduced cutting forces in non-ferrous materials such as aluminum and its alloys. The HOF-07 cutter series compatibility should be confirmed against ISCAR toolholder documentation before ordering.

Key Features

• Octagonal insert shape provides 8 usable cutting edges per insert, maximizing tool life value
• IC28 uncoated solid carbide grade optimized for non-ferrous metal machining
• Positive rake with T-Land cutting edge style for reduced cutting forces and clean chip formation
• 0.0236-inch (0.60 mm) corner radius balances edge strength and surface finish
• Maximum depth of cut of 0.1340 inches suitable for moderate material removal passes
• Screw-holding insert method ensures secure seating in compatible indexable milling bodies
• Compliant with ANSI and ISO 13399 standards for interoperability and tool data exchange

Compatibility

Designed for use with ISCAR HOF-07 series milling cutters. Verify toolholder pocket specifications and screw torque requirements against current ISCAR toolholder documentation before installation. No additional compatible model numbers were specified in the available product data.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine locked out per facility LOTO procedures. Use the appropriate ISCAR torx or hex key for the clamping screw — do not overtighten, as this can crack the carbide substrate or damage the pocket seating surface. Inspect the toolholder pocket for chips, wear, or damage before seating a new insert. Confirm insert orientation and hand designation match the cutter body before re-engaging the machine.
