Iscar 5620953 Square End Mill 5/16 in 4 Flute Solid Carbide

Product Description

The ISCAR 5620953 is a solid carbide square end mill designed for precision milling in demanding machining environments. Built to ISCAR material grade IC900 with a submicron grain carbide substrate, it carries a TiAlN finish that improves heat resistance and extends tool life in high-speed cutting. The cutter measures 5/16 inch in diameter with a 3/4 inch length of cut and a 2-1/2 inch overall length. Four spiral flutes at a 45-degree helix angle promote efficient chip evacuation and smooth surface finishes. This is a centercutting, single-end tool intended for use by machinists and tooling technicians across a range of metalworking operations.

This end mill suits milling operations on a broad range of materials, including hardened steels, cast irons, stainless steels, carbon steels, and heat-resistant superalloys, as indicated by primary workpiece material codes H, K, M, P, and S. The straight-cylindrical shank accepts standard collet and end mill holders. Its regular-length profile makes it well suited to general-purpose slot milling, profiling, and pocketing where clearance is not a constraint. It is appropriate for both CNC machining centers and manual knee mills where spindle runout is controlled and proper tool holding is used.

Key Features

• Solid carbide construction with submicron grain substrate for rigidity and wear resistance
• TiAlN coating improves thermal resistance during high-speed and dry cutting
• 45-degree helix angle spiral flutes for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute geometry for standard spindle rotation
• Straight-cylindrical shank for compatibility with standard collet and shrink-fit holders

Compatibility

Designed for use with standard straight-bore end mill holders, collet chucks, and shrink-fit holders accepting a 5/16 inch shank diameter. Suitable for milling material groups H, K, M, P, and S as specified by the manufacturer.

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. Seat the shank fully into the holder to the recommended engagement depth and verify runout with a dial indicator before beginning a cut. Follow machine tool builder guidelines and applicable shop safety procedures when setting speeds, feeds, and depth of cut.
