Iscar 5651050 Square End Mill 0.5512 in 4 Flute Carbide

Product Description

The ISCAR 5651050 is a solid carbide square end mill designed for precision metal removal in CNC milling operations. Built from submicron grain carbide, it delivers consistent edge integrity and wear resistance across demanding materials. The tool measures 0.5512 inches in diameter with a 0.9843-inch length of cut, a matching 0.5512-inch straight-cylindrical shank, and an overall length of approximately 3.27 inches (83.00 mm). A TiAlN coating provides thermal protection during high-speed cuts. The 30-degree helix angle and spiral flute geometry promote efficient chip evacuation and stable tool engagement. This end mill is suited for machinists and CNC operators working in production and job shop environments.

This end mill is intended for milling ferrous and non-ferrous metals across a broad range of workpiece material categories, including hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature superalloys, as indicated by primary workpiece material codes H, K, M, P, and S. The regular-length classification and straight-cylindrical shank make it compatible with standard collet chucks and end mill holders. It performs well in slotting, peripheral milling, and plunge cuts due to its centercutting design.

Key Features

• Solid carbide construction with submicron grain material grade for extended tool life
• TiAlN finish provides heat and oxidation resistance at elevated cutting temperatures
• 4 flutes with 30-degree helix angle for stable cutting and efficient chip flow
• Centercutting capable — supports direct plunge milling operations
• Right-hand cut, right-hand flute spiral geometry for conventional CNC spindle compatibility
• Straight-cylindrical shank fits standard collet and end mill holder tooling

Compatibility

Designed for use with standard straight-bore collet chucks and end mill holders accepting a 14.00 mm (0.5512 inch) shank diameter. Suitable for CNC machining centers and manual mills configured for right-hand rotation. Compatible workpiece material codes per ISCAR classification: 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 the tool path program is verified before loading the end mill into the holder. Confirm proper shank insertion depth and torque the collet or set screw according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use, and do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material.
