Value Collection 720-3209 Square End Mill 3/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3209 is a single-end square end mill designed for general-purpose milling operations in metal fabrication and machining shops. Built from M2 high speed steel with a bright uncoated finish, it features a 3/8 inch cutting diameter, a 3/4 inch length of cut, and a 30-degree spiral helix angle across four flutes. The right-hand cut and right-hand flute orientation suit conventional milling setups. Centercutting geometry allows the tool to plunge directly into the workpiece, adding versatility to slotting, profiling, and pocketing operations. Machinists and toolroom technicians are the primary users of this type of end mill.

This end mill fits standard milling machines, CNC machining centers, and knee mills using a 3/8 inch collet or end mill holder. The regular-length body and 2-1/2 inch overall length make it appropriate for general-depth cuts in steel, aluminum, brass, and other machinable materials where a coated carbide tool is not required. It is well suited to job shops and maintenance machining environments where HSS tooling is preferred for interrupted cuts or low-speed applications.

Key Features

• M2 high speed steel construction for toughness in interrupted cuts and low-to-moderate spindle speeds
• Four-flute design balances material removal rate with surface finish quality
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting geometry enables direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute configuration for standard milling spindle direction
• Bright uncoated finish — no coating delamination risk on regrind

Compatibility

Designed as a standard fractional-inch end mill for use in any milling machine or machining center equipped with a 3/8 inch collet, end mill holder, or ER-style chuck.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before changing tooling. Secure the shank fully within the collet or holder to the manufacturer-specified engagement depth, and verify runout with a dial indicator before beginning a cut. Do not exceed the recommended depth of cut for the material and spindle speed being used.
