Kennametal 5534254 Indexable Drill Insert Spgxmd KCU25

Product Description

The KENNAMETAL 5534254 is a solid carbide indexable drill insert designed for use in indexable drilling operations on CNC machining centers and drill bodies that accept SPGX-style inserts. Manufactured to the SPGXMD insert style with a KCU25 grade, this insert features a CVD-applied TiCN and Al2O3 coating that provides wear resistance and thermal stability during metal cutting. The square insert geometry includes a 0.25 inch inscribed circle, a thickness of 0.1252 inches, and a 0.40 mm corner radius. The MD chipbreaker geometry supports chip control across a range of workpiece materials. Installation is performed by qualified machinists or tooling technicians.

This insert is suited for production drilling applications in ferrous and other machinable materials where indexable tooling is preferred over solid drills. The right-hand cutting direction and fine grain carbide substrate make it a practical choice for moderate to high cutting-speed operations. It is packaged and sold individually, making it a direct replacement for worn or damaged inserts in compatible drill bodies without requiring full tool replacement.

Key Features

• Insert style SPGXMD with MD chipbreaker for controlled chip evacuation
• KCU25 grade fine grain solid carbide substrate
• CVD coating: TiCN plus Al2O3 for thermal and abrasion resistance
• 0.25 inch inscribed circle with 0.40 mm corner radius
• Right-hand cutting direction
• 11-degree relief angle for clearance at the cutting edge

Compatibility

Designed as a replacement insert for indexable drill bodies that accept SPGX square-style inserts with a 0.25 inch inscribed circle and a 2.65 mm mounting hole diameter.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician. Disengage machine power and confirm spindle stop before accessing the drill body. Use the appropriate Torx or hex key to secure the insert to the specified clamp torque listed on the drill body documentation. Inspect the insert pocket and seating surface for debris or wear before seating the replacement insert.
