Kennametal 5534264 Indexable Drill Insert Sppxfp KCU25

Product Description

The KENNAMETAL 5534264 is a solid carbide indexable drill insert designed for use in indexable drill bodies requiring SPPX-style inserts. It carries the KCU25 manufacturer grade and features a CVD-applied TiCN and Al2O3 coating for improved wear resistance and thermal stability during drilling operations. The insert has a 15.73 mm (0.6193 inch) inscribed circle, a thickness of 0.2343 inches, and a 0.80 mm corner radius. The FP chipbreaker geometry promotes controlled chip formation. This insert is right-hand oriented and is installed and replaced by machinists and toolroom professionals in production and job-shop environments.

This insert is suited for drilling applications in steel and similar materials where CVD-coated fine-grain carbide grades offer extended tool life. The square SPPX geometry with an 11-degree relief angle and FP chipbreaker is typical for center or peripheral insert positions in modular indexable drill systems. It fits drill bodies that accept SPPX inserts in size 15T508 and is appropriate for both CNC machining centers and manual drilling setups requiring consistent hole quality.

Key Features

• CVD-coated TiCN and Al2O3 layers for wear and heat resistance
• Fine-grain solid carbide substrate for toughness at the cutting edge
• FP chipbreaker geometry for controlled chip evacuation during drilling
• 0.80 mm corner radius reduces edge chipping at entry and exit
• 11-degree relief angle supports clean cutting action
• Right-hand cut orientation for standard drill body configurations

Compatibility

Designed as an OEM-style replacement insert for indexable drill bodies that accept SPPX-style square inserts in size 15T508 with a 5.5 mm mounting hole diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician. The drill body must be fully removed from the spindle or the machine must be powered down and locked out before insert indexing or replacement. Use the correct Torx or insert-clamp key specified by the drill body manufacturer to seat the insert properly. Inspect the insert pocket for chips or debris before seating a new insert to ensure correct positioning and clamping force.
