Kennametal 5534235 Indexable Drill Insert Sppxmd KCU40

Product Description

The KENNAMETAL 5534235 is a solid carbide indexable drill insert designed for use in indexable drilling operations where consistent performance and edge integrity are required. Carrying the SPPXMD insert style with a KCU40 grade, this square insert features a PVD-applied TiN and TiAlN dual-layer coating that provides wear resistance and thermal stability at the cutting edge. The inscribed circle measures 0.3752 inches (9.53 mm), the thickness is 0.1563 inches, and the corner radius is 0.80 mm (0.0315 inches). A licensed machinist or toolroom technician installs this insert as part of a modular boring or drilling tool assembly.

This insert is suited for right-hand cutting applications in ferrous and non-ferrous materials where a square SPPX-style seat is required. The MD chipbreaker geometry is intended to promote chip control across a range of feed and speed conditions typical in CNC turning centers, machining centers, and indexable drill bodies. It is sold individually with a minimum order quantity of 10 units, making it appropriate for production environments that maintain insert inventory by grade and geometry.

Key Features

• Solid carbide substrate with KCU40 manufacturer grade for toughness and wear resistance
• PVD TiN and TiAlN dual-layer coating for thermal stability and extended tool life
• SPPXMD insert style with MD chipbreaker for controlled chip evacuation
• Square shape with 11-degree relief angle for positive clearance geometry
• Corner radius of 0.80 mm (0.0315 inches) for edge strength and surface finish
• Right-hand cutting direction; insert size designation 09T308

Compatibility

Designed as an OEM-style replacement insert for indexable drill bodies and boring tool assemblies that accept SPPX-style square carbide inserts with a 09T308 insert size designation and a matching 3.60 mm hole diameter seating geometry.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician with the machine fully powered down and the spindle locked. Use the correct torx or hex key specified by the tool body manufacturer to seat the insert without over-torquing the clamping screw. Inspect the insert pocket for debris or damage before seating a new insert. Never mix insert grades or geometries within a multi-insert drill body unless confirmed compatible by the tool body manufacturer.
