Value Collection 720-3301 Square End Mill 1/4 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3301 is a single-end, square-profile end mill designed for milling, slotting, and peripheral cutting operations on a range of ferrous and non-ferrous workpiece materials. Manufactured from M2 high speed steel with a bright uncoated finish, this tool delivers a 0.25-inch cutting diameter and a 1.25-inch length of cut, making it well suited for applications requiring moderate depth in a compact form factor. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation and reduces heat buildup during cuts. With four flutes, this end mill provides a good balance of chip clearance and surface finish quality. It is center-cutting, allowing plunge entry directly into the workpiece.

This end mill is used in manual milling machines and CNC machining centers across job shops, maintenance facilities, and light manufacturing environments. The long-length designation and 0.375-inch shank diameter make it a practical choice for reaching into deeper features while maintaining rigidity. It is appropriate for milling keyways, slots, pockets, and profiles in mild steel, aluminum, brass, and similar materials. Machinists, toolmakers, and general maintenance technicians are the primary users of this type of tooling.

Key Features

• M2 high speed steel construction for durability across general-purpose milling applications
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation and improved surface finish
• Center-cutting capable — allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute direction for standard milling machine compatibility
• Bright uncoated finish — ready to run as-is or accept aftermarket coating if desired
• Single-end configuration with a 0.375-inch shank diameter for secure collet or end mill holder retention

Compatibility

Designed as a standard fractional-inch shank end mill compatible with collets, end mill holders, and milling chucks sized for a 3/8-inch shank diameter on conventional and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the milling machine spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet or holder and confirm proper torque on all retention hardware before initiating any cut. Inspect the cutting edges for chips or damage before each use.
