Iscar 5621806 Square End Mill 0.315 in 3 Flute Carbide

Product Description

The ISCAR 5621806 is a solid carbide square end mill designed for precision milling of non-ferrous metals. It features a 0.315-inch (8.00 mm) mill diameter, a 0.8465-inch length of cut, and three spiral flutes cut in a right-hand direction with a 45-degree helix angle. The fine-grain carbide substrate provides edge integrity during moderate to aggressive passes. This is a single-end tool with a straight cylindrical shank, suited for use in CNC machining centers and manual milling machines where close-tolerance slotting, profiling, or peripheral milling is required on aluminum, brass, copper, and similar non-ferrous workpiece materials.

This end mill is intended for non-ferrous metal applications in job shop, production, and maintenance machining environments. The 45-degree helix promotes efficient chip evacuation, which is particularly important when cutting aluminum and other gummy materials that tend to load flutes. The straight cylindrical shank mounts in standard collet chucks, end mill holders, and hydraulic chucks. It is appropriate for horizontal and vertical milling setups where a regular-length tool provides adequate reach without sacrificing rigidity.

Key Features

• 0.315-inch (8.00 mm) cutting diameter with a mill diameter tolerance of -0.025 to 0.047 mm
• Three right-hand spiral flutes at a 45-degree helix angle for effective chip evacuation
• Fine-grain solid carbide construction for edge retention on non-ferrous workpieces
• 0.8465-inch (21.50 mm) length of cut in a regular-length profile
• Straight cylindrical shank with a shank diameter tolerance of 0.000 to -0.009 mm for secure tool holding
• Non-centercutting geometry; not intended for direct plunge entry

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide end mill for standard collet, hydraulic, and end mill holder tooling systems accepting an 8.00 mm straight cylindrical shank, for use on non-ferrous metal workpieces.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the tool holder to the recommended grip length before torquing the retention mechanism according to the holder manufacturer specifications. Verify spindle runout with a dial indicator before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish. This tool is non-centercutting and must be ramped or helically interpolated into the workpiece rather than plunged axially.
