Iscar 5621960 Square End Mill 0.75in 6-flute Tialn Carbide

Product Description

The ISCAR 5621960 is a solid carbide square end mill designed for high-performance milling in metal-cutting applications. Built to ISCAR material grade IC903 and finished with a TiAlN coating, this tool delivers hardness and heat resistance suited for aggressive cutting conditions. It features a 0.75 inch diameter, a 1.5 inch length of cut, and a 4 inch overall length. The 6-flute geometry combined with a 45-degree spiral helix angle promotes efficient chip evacuation and surface finish quality. Installed by machinists and CNC operators, this end mill is a direct fit for vertical and horizontal machining centers running right-hand spindle rotation.

This end mill is suited for finish and semi-finish milling passes on steel, stainless steel, and hardened materials where TiAlN coating provides thermal protection. The straight cylindrical shank measures 0.75 inches in diameter, compatible with standard ER collet chucks, end mill holders, and hydraulic tool holders. The regular length classification makes it a practical choice for general-purpose side milling, slotting, and profiling operations where extended reach is not required. Note that this tool is not centercutting and should not be used for direct plunge entry.

Key Features

• Solid carbide construction with IC903 material grade for wear resistance in hard materials
• TiAlN coating provides high-temperature resistance and extended tool life
• 6-flute spiral design with 45-degree helix angle for efficient chip flow and improved surface finish
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• 0.75 inch straight cylindrical shank fits standard toolholding systems
• Non-centercutting geometry — not intended for plunge milling

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 0.75 inch straight cylindrical shank with right-hand cutting direction.

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 locked-out state before changing tooling. Seat the shank fully and evenly in the toolholder to the recommended gauge line and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before initiating a cutting pass.
