Iscar 5620426 Square End Mill 0.189 in 3 Flute Carbide

Product Description

The ISCAR 5620426 is a solid carbide square end mill designed for precision metal removal in demanding machining environments. Built from submicron grain carbide, this 3-flute tool measures 0.189 inches in diameter with a 0.2362-inch length of cut. A TiAlN coating provides thermal resistance and extended tool life at elevated cutting temperatures. The spiral flute geometry with a 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 57 mm overall length, this stub-length configuration delivers rigidity for short-reach applications. Licensed machinists and CNC operators working in job shops or production environments are the primary users of this tool.

This end mill is suited for milling operations on a range of workpiece materials including hardened steels, cast iron, stainless steel, carbon and alloy steels, and superalloys, corresponding to material codes H, K, M, P, and S. The Weldon flat shank provides a positive drive connection in side-lock tool holders, reducing pullout risk during aggressive cuts. Stub-length design makes it a strong choice for shallow pocketing, slotting, and profiling where tool deflection must be minimized.

Key Features

• Submicron grain solid carbide construction for hardness and wear resistance
• TiAlN finish for high-temperature performance and extended tool life
• 3 flutes with 38-degree right-hand spiral for efficient chip flow
• Weldon flat shank for secure seating in side-lock holders
• Stub-length body provides rigidity in short-reach setups
• Right-hand cut compatible with standard CNC and manual milling spindles

Compatibility

Designed for use in standard 6 mm Weldon flat side-lock tool holders. Compatible with workpiece material categories H, K, M, P, and S as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before mounting or removing the end mill. Seat the Weldon flat against the set screw in the tool holder and torque the set screw per the tool holder manufacturer specification. Confirm tool runout with a dial indicator before beginning any cut, and verify that cutting parameters are appropriate for the workpiece material and machine capability.
