Iscar 5620517 Square End Mill 7.7mm 3 Flute Carbide

Product Description

The ISCAR 5620517 is a solid carbide square end mill designed for precision milling operations in metalworking applications. With a 7.7 mm cutting diameter and a 9 mm length of cut, this three-flute tool is built for material removal in steel, cast iron, stainless steel, heat-resistant alloys, and non-ferrous metals. The 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiAlN coating improves heat resistance and extends tool life in demanding cutting environments. This end mill is manufactured to ISCAR material grade IC900 and is sized in the stub length category for added rigidity.

This end mill is suited for CNC machining centers and manual milling machines in job shop, production, and maintenance environments. The 8 mm Weldon flat shank provides secure tool holding and resistance to pullout during aggressive cuts. Right-hand cutting and right-hand flute direction make it compatible with standard spindle setups. Machinists working with hardened steels, stainless alloys, titanium, and superalloys will find this tool appropriate given its primary workpiece material codes of H, K, M, P, and S. It is a single-end tool intended for direct replacement when worn.

Key Features

• 7.7 mm cutting diameter with a mill diameter tolerance of -0.025 to 0.047 mm
• 3 flutes with a 38-degree right-hand spiral helix for efficient chip flow
• Solid carbide construction at ISCAR IC900 material grade
• TiAlN coating for elevated heat resistance and extended tool life
• 8 mm Weldon flat shank with shank diameter tolerance of 0.000 to -0.009 mm
• Stub length classification for increased rigidity in tight setups

Compatibility

Designed as an OEM-style solid carbide square end mill replacement suitable for standard 8 mm Weldon flat shank tool holders used in right-hand CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the Weldon flat shank firmly in a compatible end mill holder or collet chuck, tightening set screws to the tool holder manufacturer's specified torque. Verify runout with a dial indicator before beginning a cut to confirm proper seating and avoid premature tool wear.
