Iscar 5650520 Square End Mill 6mm 3 Flute Solid Carbide

Product Description

The ISCAR 5650520 is a solid carbide square end mill designed for precision milling of non-ferrous metals. With a 6 mm (0.2362 inch) cutting diameter and 8 mm length of cut, this stub-length tool delivers rigid, accurate material removal in tight setups. The three-flute geometry paired with a 38-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action. Material grade IC08 suits this tool to aluminum, copper, brass, and similar non-ferrous workpiece materials. The bright, uncoated finish is appropriate for applications where coating interaction with the workpiece is a concern. Machinists and CNC operators working in job shop or production environments will find this end mill well-suited to slotting, profiling, and contouring operations.

This end mill is intended for use on CNC machining centers and manual mills processing non-ferrous metals (workpiece material code N). The stub length of cut range of 0.3000 to 0.5000 inches suits shallow-to-moderate-depth passes where tool deflection must be minimized. The straight cylindrical shank at 6 mm diameter provides secure clamping in collet chucks, end mill holders, and hydraulic toolholders. Single-end construction means the tool is replaced when the cutting end reaches end of life. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle rotation.

Key Features

• Solid carbide construction in material grade IC08 for non-ferrous metal milling
• Three right-hand spiral flutes at 38-degree helix angle for efficient chip evacuation
• 6 mm cutting diameter with -0.025 to 0.047 mm diameter tolerance
• Stub-length design (8 mm LOC, 39 mm OAL) for rigidity in short-reach applications
• Center-cutting capable — supports plunge entry
• Bright/uncoated finish suitable for non-ferrous and aluminum workpieces

Compatibility

Designed for use in standard collet chucks, end mill holders, and hydraulic toolholders accepting a 6 mm straight cylindrical shank. Intended primarily for non-ferrous metal workpiece materials including aluminum, copper, and brass alloys.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool release mechanism is engaged before inserting or removing the end mill. Use a calibrated torque wrench when tightening collet nuts or set screws to the toolholder manufacturer's specification. Confirm runout at the cutting edge with a dial indicator before beginning any production run to avoid premature tool wear or workpiece damage.
