Value Collection 720-4104 Square End Mill 3/16 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4104 is a double-end, four-flute square end mill manufactured from M2 high speed steel. It is designed for milling slots, shoulders, and profiles in ferrous and non-ferrous metals on manual mills and CNC machining centers. The cutting diameter is 0.1875 inches (3/16 inch) with a 0.5-inch length of cut, a 0.375-inch (3/8 inch) shank diameter, and a 3.25-inch overall length. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during light-to-moderate material removal operations. The bright, uncoated finish makes it straightforward to inspect for wear. Machinists and tool-and-die technicians are the primary users of this tool.

This end mill is suited for general-purpose milling work in job shop, maintenance, and production environments. The double-end configuration doubles usable cutting life by providing two serviceable ends on a single blank. The centercutting geometry allows the tool to plunge directly into workpiece material, making it useful for pocketing operations without a pre-drilled entry point. Typical applications include slotting, profiling, and step milling in mild steel, aluminum, brass, and similar machinable materials.

Key Features

• Double-end design provides two cutting ends for extended tool life
• M2 high speed steel construction offers a balance of toughness and wear resistance
• Centercutting geometry enables direct plunge entry into workpiece material
• 30-degree helix angle supports efficient chip evacuation and smooth cutting action
• Right-hand cut and right-hand spiral flute configuration for standard spindle use
• Bright, uncoated finish simplifies visual wear inspection between operations

Compatibility

Designed as a general-purpose replacement or stock end mill for standard milling machine and CNC machining center spindles accepting a 3/8-inch shank diameter.

Installation Notes

This tool is installed by machinists in milling machine or machining center spindles using a collet or end mill holder rated for the 3/8-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator after seating the shank to avoid premature cutting edge wear. Follow shop speeds-and-feeds guidelines for the specific workpiece material and depth of cut.
