Ingersoll Cutting Tools 4209905 Milling Insert TKA1370R01

Product Description

The INGERSOLL CUTTING TOOLS 4209905 is a solid carbide milling insert designed for high-performance metal cutting in demanding industrial machining applications. Manufactured to ANSI and ISO standards under the ANSI/ISO code TKA1370R01 IN2505, this insert carries a PVD-applied TiAlN and TiN dual coating that extends tool life and resists heat buildup during aggressive milling cuts. The IN2505 grade uses a micrograin carbide substrate, which provides a fine balance of hardness and toughness. With a positive rake geometry and a honed cutting edge, the insert promotes clean chip formation and reduces cutting forces. It is a right-hand configuration with a single cutting edge and an irregular insert shape sized at insert size code 1370, measuring approximately 0.5394 inches in width.

This insert is engineered for milling operations across a broad range of workpiece materials, including steel, stainless steel, cast iron, superalloys, titanium, and hard materials - covering ISO material groups P, M, K, S, and H. It is suited for production environments where tool consistency and surface finish quality are critical. Typical applications include face milling, shoulder milling, and slot milling on CNC machining centers. The TKA series insert style targets both roughing and finishing passes depending on feed and depth of cut parameters selected by the operator.

Key Features

• Solid micrograin carbide substrate in Ingersoll IN2505 grade for hardness and toughness in interrupted cuts
• PVD-applied TiAlN and TiN dual coating for elevated heat resistance and extended flank wear life
• Positive rake with honed cutting edge reduces cutting forces and promotes clean chip evacuation
• Covers ISO material groups P, M, K, S, and H - suitable for steel, stainless, cast iron, superalloys, titanium, and hard materials
• Right-hand, single cutting edge configuration in TKA insert style, size code 1370
• Conforms to ANSI and ISO insert standards for consistent fit and interchangeability

Compatibility

This insert is compatible with Ingersoll TC and TD cutter series toolholders. It is designed as a direct-fit replacement for applications specifying the TKA1370R01 IN2505 insert in those cutter platforms.

Installation Notes

Milling insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Use the appropriate Torx or hex key driver as specified by the cutter body manufacturer to seat the insert clamp screw - do not overtighten by feel alone, follow the cutter body torque specification. Inspect the insert pocket and seating surface for chips or debris before installing a new insert. Always verify correct insert orientation and hand designation before resuming machine operation.
