Iscar 5620951 Square End Mill 3/16 in 4 Flute Solid Carbide

Product Description

The ISCAR 5620951 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 3/16-inch diameter with a 1/2-inch length of cut and a 2-inch overall length. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of ferrous and non-ferrous materials. A TiAlN coating extends tool life by improving heat resistance at the cutting edge. This tool is used by machinists and toolroom professionals operating CNC mills, knee mills, and manual milling equipment.

This end mill is suited for slot milling, profiling, and peripheral milling operations on workpieces classified under material codes H, K, M, P, and S — covering hardened steels, cast irons, stainless steels, general steels, and heat-resistant superalloys. The straight cylindrical shank fits standard collet and end mill holders accepting a 3/16-inch shank. Its regular-length geometry makes it a practical choice for general-purpose material removal where extended reach is not required.

Key Features

• Solid carbide construction using ISCAR material grade IC900 for rigidity and wear resistance
• TiAlN coating provides elevated heat resistance and extended tool life in demanding cuts
• 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• 4-flute configuration balances feed rate capability with chip clearance
• Center-cutting design allows plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute direction for standard spindle rotation

Compatibility

Designed for use with standard collet chucks and end mill holders accepting a 3/16-inch straight cylindrical shank. Suitable for machining material codes H, K, M, P, and S as specified by the manufacturer.

Installation Notes

Installation is performed by a qualified machinist. Secure the shank fully into a clean, properly sized collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer's specifications. Inspect the cutting edges for chips or damage before mounting. Ensure spindle speed and feed rate are set per the material being machined and the manufacturer's recommended cutting parameters before engaging the workpiece.
