Value Collection Sean 42AFTN C2 Milling Insert Solid Carbide

Product Description

The VALUE COLLECTION SEAN 42AFTN C2 is a solid carbide milling insert designed for metal cutting and material removal in milling operations. Conforming to the ISO designation SEAN1203AFTN, this insert features a square shape with a 90-degree included angle and a neutral hand orientation. The Al2O3 (aluminum oxide) coating provides thermal resistance and wear protection during high-speed cutting passes. At 0.1250 inches thick with a 0.5-inch inscribed circle and a 20-degree relief angle, it is suited for finish and semi-finish milling work. Machinists and tool-and-die professionals are the typical end users.

This insert is intended for use in compatible square-seat milling toolholders and face mill bodies that accept SEAN-style inserts. The C2 carbide material grade makes it appropriate for general-purpose machining of cast iron, non-ferrous metals, and similar workpiece materials at moderate cutting speeds. It is sold individually with a minimum order quantity of 10 units, making it suitable for shop restocking or initial tooling setups where consistent grade and geometry are required across multiple insert pockets.

Key Features

• Solid carbide construction with Al2O3 coating for extended tool life in abrasive cutting conditions
• Square insert shape with 90-degree included angle for versatile milling geometries
• 20-degree relief angle reduces cutting forces and improves chip clearance
• Neutral hand design compatible with both right- and left-hand toolholder setups
• ISO code SEAN1203AFTN ensures direct cross-reference to standard insert catalogs
• C2 carbide grade rated for general-purpose cutting of cast iron and non-ferrous materials

Compatibility

Designed as a replacement or restocking insert for milling toolholders and cutter bodies that accept SEAN-style square inserts with a 0.5-inch inscribed circle and SEAN1203AFTN ISO geometry.

Installation Notes

Insert seating and torque should follow the toolholder manufacturer specifications for SEAN-style square inserts. Machinists should inspect the insert pocket for debris or damage before seating a new insert. Machine spindle must be fully stopped and the machine locked out before any insert change. Discard worn or chipped inserts rather than rotating them beyond recommended use to avoid workpiece damage or toolholder seat wear.
