Kennametal 5534234 Indexable Drill Insert Sppx KCU40 Carbide

Product Description

The KENNAMETAL 5534234 is a solid carbide indexable drill insert designed for high-performance drilling applications in metal cutting environments. Manufactured in the SPPX insert style with a square shape, this insert carries the KCU40 grade and features a PVD-applied dual-layer TiN and TiAlN coating for enhanced wear resistance and thermal stability. The inscribed circle measures 0.3752 inches (9.53 mm), insert thickness is 0.1563 inches, and the corner radius is 0.0315 inches (0.80 mm). The RHP chipbreaker geometry promotes efficient chip evacuation. This insert is installed by machinists and toolroom technicians working with indexable drill bodies on CNC or manual machining centers.

The 5534234 is suited for right-hand cutting operations in indexable drill systems that accept SPPX-style inserts at insert size 09T308. Typical applications include through-hole and blind-hole drilling in ferrous and non-ferrous metals where controlled chip flow and edge life are priorities. The dual-coating stack makes this insert a practical choice for production drilling at moderate to elevated cutting speeds where heat generation at the cutting edge is a factor.

Key Features

• Solid carbide substrate with PVD TiN and TiAlN dual-layer coating for wear resistance and heat management
• SPPX insert style, square shape, insert size 09T308 for indexable drill body compatibility
• RHP chipbreaker geometry promotes positive chip control and evacuation in drilling operations
• Right-hand cutting direction with an 11-degree relief angle for reduced cutting forces
• Corner radius of 0.0315 inches (0.80 mm) balances edge strength and surface finish
• Hole diameter of 0.1417 inches (3.60 mm) for standard insert clamping screw fitment

Compatibility

Designed as a replacement-style indexable drill insert for drill bodies that accept SPPX square inserts at the 09T308 insert size. Confirm drill body manufacturer specifications before installation to verify insert seat geometry and screw torque requirements.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and de-energize all machine spindles before changing inserts. Use the correct insert clamping screw and a calibrated torque wrench per the drill body manufacturer specifications — do not over-torque or under-torque the clamping screw. Inspect the insert pocket and seating surface for chips or debris before seating the new insert.
