Ingersoll Cutting Tools 4209861 Milling Insert TKA0920R01

Product Description

The INGERSOLL CUTTING TOOLS 4209861 is a solid carbide milling insert designed for demanding metal removal applications in industrial machining environments. Manufactured to ANSI and ISO standards under the designation TKA0920R01 IN2505, this insert features a TiAlN and TiN dual-layer coating applied via PVD process, delivering thermal resistance and wear protection at the cutting edge. The micrograin carbide substrate and honed cutting edge style support consistent chip formation in high-feed and interrupted-cut scenarios. With a positive rake geometry and a single right-hand cutting edge, this insert is suited for precision milling where controlled engagement and predictable tool life are priorities.

This insert is intended for use in milling operations across a broad range of workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials, corresponding to ISO material groups P, M, K, S, and H. It is compatible with TC and TD cutter series bodies and carries the IN2505 manufacturer grade designation. Typical installation environments include CNC machining centers in production shops handling ferrous and exotic alloy workpieces. This insert does not include a chip breaker and is sized at insert size code 0920.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the cutter body is fully secured and the spindle is locked out before seating or removing inserts. Use the appropriate torx or insert clamping hardware specified by the cutter body manufacturer - do not substitute fastener types. Verify insert orientation and hand designation match the cutter body pocket before resuming operation.
