Iscar 5601272 Milling Insert Sekr 42AFN-76 IC520M Square

Product Description

The ISCAR 5601272 is a square milling insert carrying the ANSI designation SEKR 42AFN-76 and manufactured in IC520M-grade solid carbide with a CVD-applied TiCN coating. Measuring 0.5000 inches in both length and width with a thickness of 0.1250 inches and an inscribed circle diameter of 0.5000 inches, this single-sided insert seats into F45E-series face mill bodies using a clamp-type holding method. The positive rake geometry, 90-degree included angle, and honed cutting edge style produce clean, free-cutting action on a range of ferrous workpiece materials. Four usable cutting edges per insert and a maximum depth of cut of 0.2560 inches make this a practical choice for production milling operations in steel, stainless steel, and cast iron.

This insert is designed for use in F45E-series ISCARMILL cutter bodies and is suited for face milling and shoulder milling applications in both steel and cast iron workpieces. The IC520M grade with CVD TiCN coating provides wear resistance under moderate to high cutting speeds common in production-floor environments. Right-hand cutting geometry makes this insert compatible with standard right-hand milling setups. The chip breaker designation 76 is engineered for controlled chip formation across the primary workpiece materials listed. This insert is sold individually and is appropriate for professional machining environments where consistent insert performance and grade repeatability are required.

Key Features

• IC520M solid carbide grade with CVD-applied TiCN coating for wear resistance in ferrous materials
• Square insert shape with 90-degree included angle and positive rake for free-cutting geometry
• Four cutting edges per insert, maximizing cost-per-edge value in production runs
• Maximum depth of cut of 0.2560 inches suitable for face and shoulder milling passes
• Honed cutting edge style reduces microchipping at entry and exit on steel and cast iron
• Compatible with F45E-series ISCARMILL cutter bodies using clamp-type insert retention

Compatibility

Designed for use with F45E-series ISCARMILL cutter bodies. Compatible with right-hand milling setups. ANSI code SEKR 42AFN-76 IC520M; ISO code SEKR 1203AFN-76. Conforms to ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Before replacing inserts, ensure the spindle is fully stopped, locked out, and the machine is de-energized per shop lockout/tagout procedures. Seat the insert firmly against the pocket locating surfaces and secure the clamp to the manufacturer-specified torque using a calibrated torque wrench — refer to the cutter body documentation for the correct torque value, as it is not specified here. Inspect the insert pocket for chips, debris, or wear before seating a new insert to ensure proper contact and runout.
