Iscar 5620519 Square End Mill 0.4606 in 3 Flute Carbide

Product Description

The ISCAR 5620519 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 0.4606-inch (11.70 mm) mill diameter and a 0.4724-inch (12.00 mm) length of cut, this stub-length tool delivers rigidity and accuracy in tight setups. The three-flute geometry paired with a 38-degree spiral helix angle optimizes chip evacuation and cutting efficiency. A TiAlN finish provides thermal resistance and extended tool life in high-temperature cutting environments. The Weldon flat shank ensures positive drive retention in compatible holders. This end mill is intended for use by machinists and CNC operators in production and job-shop environments.

This end mill is rated for use across multiple primary workpiece material categories, including hardened materials (H), cast iron and non-ferrous (K), stainless steel (M), steels (P), and superalloys and titanium (S). The stub length configuration makes it well suited for applications where minimal overhang and maximum stiffness are required, such as shallow-pocket milling, slotting, and shoulder milling. The right-hand cut with right-hand flute direction is standard for conventional CNC milling center use. Submicron grain carbide construction supports consistent edge retention across extended production runs.

Key Features

• Solid carbide submicron grain construction for edge retention and wear resistance
• TiAlN coating for thermal protection in dry or high-speed cutting conditions
• 38-degree helix angle promotes efficient chip flow in multi-material applications
• Weldon flat shank provides positive drive and prevents tool pullout under load
• Stub length design maximizes rigidity and minimizes deflection
• Three-flute geometry balances cutting speed and chip clearance

Compatibility

Designed for use with Weldon flat shank tool holders accepting a 12.00 mm (0.4724-inch) shank diameter. Suitable for machining hardened steels, stainless steels, cast iron, non-ferrous alloys, and superalloys as indicated by primary workpiece material codes H, K, M, P, and S.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before installing or removing the end mill. Seat the Weldon flat against the set screw in the holder to prevent axial pullout during cutting. Verify shank diameter tolerance compatibility with the holder before use, and inspect the cutting edge for chips or damage prior to each setup.
