Iscar 5650445 Square End Mill 0.2165 in 2 Flute Carbide

Product Description

The ISCAR 5650445 is a solid carbide square end mill designed for precision milling of non-ferrous metals. It features a 0.2165-inch (5.50 mm) mill diameter and a 0.6299-inch (16.00 mm) length of cut, making it well suited for fine finishing and profiling operations in tight tolerances. The two-flute configuration and 30-degree helix angle promote efficient chip evacuation in aluminum, brass, copper, and similar materials. Fine-grain carbide construction provides edge stability and wear resistance during high-speed cutting. This tool is installed by CNC machinists and tool-and-die professionals working on production milling centers and vertical machining centers.

This end mill is intended for milling non-ferrous metals in light to medium material removal applications. Its regular-length geometry and straight cylindrical shank suit standard ER collet chucks and end mill holders commonly found in production shop environments. The centercutting design allows plunge cutting as well as conventional peripheral and slot milling. Right-hand cut and right-hand flute spiral geometry are standard for conventional and climb milling passes on CNC equipment.

Key Features

• Solid fine-grain carbide construction for edge stability and extended tool life in non-ferrous materials
• 0.2165-inch (5.50 mm) diameter with a 0.6299-inch (16.00 mm) length of cut
• Two flutes with 30-degree helix angle for efficient chip flow in aluminum and non-ferrous alloys
• Centercutting design enables plunge entry without a pre-drilled hole
• Right-hand cut, right-hand spiral flute for use on standard CNC milling spindles
• Uncoated finish suited for non-ferrous applications where coating adhesion is not required

Compatibility

Designed as an OEM-style solid carbide square end mill for use with standard straight cylindrical shank tool holders and ER collet systems; primary workpiece material compatibility is non-ferrous metals (material code N).

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Confirm runout at the collet or holder meets the tolerance requirements of the application before cutting. Shank diameter tolerance is 0.000 to -0.008 mm, so verify holder bore compatibility prior to use.
