Ingersoll Cutting Tools 5516496 Indexable Drill Insert

Product Description

The INGERSOLL CUTTING TOOLS 5516496 is an indexable drill insert in the XCMT style, manufactured from solid carbide with a PVD-applied coating and designated grade TT8020. This insert features an 83.5-degree diamond shape with a positive rake geometry and a 7-degree relief angle, delivering aggressive chip evacuation and edge stability in demanding drilling applications. The chipbreaker style is TC, and the inscribed circle measures 0.2200 inches. With two cutting edges per insert and a corner radius of 0.0160 inches, it is suited for high-productivity indexable drill tooling systems. Qualified machinists and CNC operators install and index these inserts during tooling changeovers.

This insert is engineered for drilling into steel, stainless steel, super-alloys, and titanium, corresponding to ISO material group codes P, M, and S. Its PVD coating and TT8020 grade make it especially effective in applications where tool life and surface finish consistency are critical. Typical use scenarios include CNC machining centers and turning centers running indexable drill bodies that accept XCMT-style inserts. It suits both production-volume and job-shop drilling operations across these workpiece material categories.

Key Features

• Solid carbide construction with PVD coating for extended wear resistance
• TT8020 manufacturer grade optimized for steel, stainless, super-alloys, and titanium
• 83.5-degree diamond shape with positive rake for efficient chip formation
• TC chipbreaker design for controlled chip flow in through and blind-hole drilling
• Two cutting edges per insert for cost-effective indexing
• 7-degree relief angle reduces cutting forces at the edge

Compatibility

Designed as an OEM-style replacement or production insert for indexable drill bodies that accept XCMT-style inserts with an insert size code of 050204.

Installation Notes

Indexable drill inserts of this type are installed and indexed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing any insert. Use the correct torx or hex key specified by the drill body manufacturer to achieve proper clamping force - do not overtighten, as carbide inserts are brittle and can fracture. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
