Value Collection 720-4036 Square End Mill 3/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4036 is a double-end, four-flute square end mill designed for general-purpose milling operations in ferrous and non-ferrous metals, plastics, and composites. Built from M2 high speed steel with a bright uncoated finish, this tool features a 3/8 inch cutting diameter, a 3/4 inch length of cut, and a 30-degree helix angle. The spiral flute geometry and right-hand cutting direction promote efficient chip evacuation during peripheral and slot milling. At 3.5 inches overall length with a matched 3/8 inch shank diameter, it fits standard collet chucks and end mill holders on knee mills, CNC machining centers, and manual milling machines.

This end mill is suited for light-to-medium material removal in job shop, tool room, and maintenance machining environments. The double-end configuration doubles usable tool life, making it a cost-effective choice for shops running general milling, profiling, and slotting operations. It is not center-cutting, so it requires a pre-drilled or pre-bored entry point for plunge applications. No extended reach, coolant-through capability, or chipbreaker geometry is present on this tool.

Key Features

• Double-end design provides two usable cutting ends per tool
• M2 high speed steel construction offers toughness in interrupted cuts and moderate heat resistance
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Bright uncoated finish suitable for a wide range of general-purpose materials
• Right-hand cut and right-hand flute spiral for standard milling machine spindles
• Regular length classification fits most standard collet and end mill holder setups

Compatibility

Designed as a general-purpose replacement or stock end mill for standard 3/8 inch collet chucks and end mill holders on knee mills, CNC vertical machining centers, and manual milling machines using fractional inch tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the collet or holder and torque the retention hardware to the machine or toolholder specification. Because this tool is not center-cutting, avoid direct plunge entry into solid material without a pre-drilled relief hole.
