Iscar 3398317 Square End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The ISCAR 3398317 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 1/2 inch mill diameter and 3 inch length of cut, this single-end tool handles deep slotting, profiling, and peripheral milling with consistent edge integrity. The 38-degree helix angle and TiAlCN coating work together to improve chip evacuation and extend tool life in ferrous and non-ferrous materials. The submicron carbide grade provides the hardness and wear resistance demanded by high-production environments. Licensed machinists and CNC operators working in job shops or production facilities will find this tool suited to demanding cut cycles.

This end mill is built for use in vertical machining centers, CNC mills, and manual milling machines where a 1/2 inch shank is standard. The 6 inch overall length provides extended reach for deeper setups without requiring a separate reach-extension toolholder. The variable index flute geometry reduces chatter and improves surface finish across a range of materials. Right-hand cutting direction and right-hand flute spiral make it compatible with standard spindle rotation on conventional machining equipment.

Key Features

• Solid carbide construction in submicron grade for hardness and edge retention
• TiAlCN coating reduces friction and extends tool life in demanding cuts
• 38-degree helix angle promotes efficient chip evacuation
• Variable index flute geometry reduces harmonic chatter during milling
• Center-cutting capable for direct plunge entry
• Single-end design with 4 flutes for balance between chip room and cutting edges

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC and manual milling machines accepting a 1/2 inch straight shank end mill in ER, Weldon, or shrink-fit toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and torque retention screws or collet nuts per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
