Kennametal 5352356 Corner Radius End Mill 3/8 in Ceramic

Product Description

The KENNAMETAL 5352356 is a ceramic corner radius end mill engineered for demanding material removal in superalloys and titanium. It features a 3/8-inch mill diameter, a 0.047-inch corner radius, and four right-hand spiral flutes with a high helix angle. The SiAlON ceramic substrate delivers the thermal resistance needed to maintain cutting performance at elevated temperatures common in aerospace and precision machining applications. With an overall length of 2.5 inches and a length of cut of 9/32 inches, this single-end mill is suited for both roughing and finishing passes where tool life and edge stability matter most.

This end mill is designed for milling superalloys and titanium in high-performance manufacturing environments, including aerospace, power generation, and medical component machining. It fits setups requiring extended reach, with a 3/4-inch reach length and a neck diameter of 0.360 inches. The straight cylindrical shank is compatible with HC-HSK Form A toolholding systems. Its extended reach geometry makes it effective in pockets and contoured surfaces where standard-length tools cannot reach the workpiece.

Key Features

• SiAlON ceramic cutting material provides high thermal resistance for superalloy and titanium applications
• Corner radius of 0.047 inches reduces stress concentration and extends edge life during interrupted cuts
• Four right-hand spiral flutes with high helix angle and normal pitch for efficient chip evacuation
• Extended reach design with 3/4-inch reach length and 0.360-inch neck diameter for deep-feature access
• Suitable for both roughing and finishing material removal in a single tool
• Single-end configuration from the EADE series; no chipbreaker, no coolant-through

Compatibility

Designed for use with HC-HSK Form A toolholding systems. Intended for machining superalloys and titanium workpieces. Part of the KENNAMETAL EADE series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Confirm the toolholder bore and retention system are compatible with the 3/8-inch straight cylindrical shank before mounting. Power down and lock out the machine spindle before loading or removing the tool. Ceramic end mills are brittle relative to carbide — avoid interrupted cuts without adequate setup rigidity and do not exceed recommended run-out tolerances for the toolholder.
