Kennametal 4042933 Spgxfp KCU40 Indexable Drill Insert

Product Description

The KENNAMETAL 4042933 is a solid carbide indexable drill insert in the SPGXFP style, designed for use in indexable insert drills in demanding metal-cutting applications. It carries KENNAMETAL grade KCU40 with a PVD-applied TiN and TiAlN multilayer coating that supports elevated cutting speeds and extends tool life in interrupted cuts and difficult-to-machine materials. The insert has a 0.307-inch inscribed circle, a thickness of 0.1252 inches, and a corner radius of 0.0313 inches. The FP chipbreaker geometry promotes controlled chip evacuation during drilling. This insert is sold individually and requires a minimum order of 10 units.

This insert is suited for machining centers and CNC drilling operations in job shops, production facilities, and aerospace or metalworking environments. The SPGX insert style is commonly paired with modular indexable drill bodies for drilling steel, stainless steel, and cast materials at high feed rates. The KCU40 grade with PVD TiAlN coating is particularly effective in applications where heat resistance and edge toughness are priorities. Machinists and toolroom professionals handling precision drilling operations will typically specify this insert when long run lengths and consistent hole quality are required.

Key Features

• SPGXFP insert style with FP chipbreaker for controlled chip flow during drilling
• KCU40 solid carbide grade with PVD TiN and TiAlN coating for extended wear resistance
• 0.307-inch inscribed circle for precise fit in compatible drill bodies
• 0.0313-inch corner radius suited for finish and semi-finish drilling operations
• 0.1252-inch insert thickness providing rigidity at the cutting edge
• Insert size designation 070308 for toolholder cross-referencing

Compatibility

Designed as an OEM-style replacement or standard-production indexable insert for indexable drill bodies that accept the SPGX insert style with a 0.112-inch hole diameter seating.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before seating or replacing inserts. Use the correct torx or hex key specified by the drill body manufacturer to achieve proper clamping torque without over-torquing the insert screw. Inspect the insert pocket for debris or damage before seating a new insert to ensure full contact and accurate positioning.
