Ingersoll Cutting Tools 5521777 Indexable Drill Insert

Product Description

The INGERSOLL CUTTING TOOLS 5521777 is an indexable drill insert designed for high-performance drilling and boring operations in demanding machining environments. Identified by ANSI and ISO code XCMT080304TC TT9080, this solid carbide insert features an AlTiN and TiN coating applied via PVD process, providing excellent heat and wear resistance. The insert carries manufacturer grade TT9080 and is engineered with a positive rake angle and a 7-degree relief angle for efficient chip formation and reduced cutting forces. With 2 cutting edges, this insert delivers consistent performance across multiple indexing cycles before replacement is required.

This insert is primarily suited for machining stainless steel, superalloys, and titanium - material categories classified under ISO codes M and S. It is designed for use in indexable drill bodies that accept XCMT-style inserts in size code 080304. Typical applications include production drilling on CNC machining centers and turning centers where tight tolerances and difficult-to-machine alloys demand a reliable, wear-resistant cutting edge. The TC chipbreaker geometry supports controlled chip evacuation in deep-hole and interrupted-cut scenarios.

Key Features

• Solid carbide construction with PVD-applied AlTiN and TiN coating for heat and wear resistance
• Diamond (83.5-degree included angle) insert shape for strong, stable cutting geometry
• Positive rake with 7-degree relief angle reduces cutting forces on difficult alloys
• TC chipbreaker promotes controlled chip flow in stainless steel and superalloy applications
• 2 indexable cutting edges extend usable insert life
• PVD coating process preserves sharp edge integrity at the cutting tip

Compatibility

Designed for use in indexable drill bodies and boring systems that accept XCMT-style inserts with size code 080304. Optimized for primary workpiece materials including stainless steel, superalloys, and titanium (ISO material codes M and S).

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine spindle fully stopped and locked out per facility LOTO procedures. Use the correct torx or hex key as specified by the drill body manufacturer when seating the insert - never overtighten, as carbide inserts are brittle and can crack under excessive clamp force. Inspect the insert pocket and clamping screw for wear or debris before indexing or replacing the insert. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.
