Value Collection 720-4120 Square End Mill 1in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4120 is a double-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from M2 high speed steel with a bright/uncoated finish, it offers a 1 inch cutting diameter and a 1-7/8 inch length of cut. The double-end design provides two usable cutting ends, extending tool life between changeouts. With four spiral flutes and a 30-degree helix angle, this end mill supports efficient chip evacuation and smooth cutting performance. It is center-cutting capable, allowing plunge entry into workpieces. Right-hand cutting and right-hand flute direction are standard on this tool.

This end mill is suited for use in vertical milling machines and CNC machining centers where fractional-inch tooling is standard. It handles profiling, slotting, and peripheral milling in ferrous and non-ferrous materials. The M2 HSS construction makes it a practical choice for shops that require a reliable general-purpose tool without the cost of carbide. Machinists and tool-and-die professionals are the primary installers and operators of this tooling.

Key Features

• Double-end design delivers two cutting ends per tool, reducing per-cut tooling cost
• M2 high speed steel construction provides good toughness and wear resistance in general machining
• Center-cutting capability allows direct plunge cuts without pre-drilling
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Four spiral flutes support efficient material removal in profiling and slotting applications
• Bright/uncoated finish is compatible with a wide range of cutting fluids and workpiece materials

Compatibility

Designed as an OEM-style replacement or standard tooling option for vertical mills and CNC machining centers accepting a 1 inch shank diameter with fractional-inch collets or end mill holders.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Use a properly sized collet or end mill holder rated for 1 inch shank diameter to prevent runout. Inspect both cutting ends for damage before use and never exceed the machine manufacturer's recommended spindle speed or feed rate for the workpiece material.
