Value Collection 723-3211 Cobalt Square End Mill 1/2 in 4 Flute

Product Description

The VALUE COLLECTION 723-3211 is a single-end cobalt square end mill designed for milling ferrous and tough alloy materials in machining center and manual mill applications. Built from M42 cobalt high-speed steel, the cutter runs a 1/2-inch diameter with a 1-1/4-inch length of cut and a 30-degree right-hand helix. The four-flute geometry delivers a strong finish cut on steel, stainless, and hardened materials where standard HSS tools deflect or wear prematurely. The bright uncoated finish makes tool wear easy to monitor during use. Overall length is 3-1/4 inches with a 1/2-inch straight shank. Weight is 0.18 pounds.

This end mill is suited for side milling, slotting, and profiling operations on steel, cast iron, high-temperature alloys, and similar tough materials. The centercutting geometry allows it to plunge directly into a workpiece, making it practical for pocketing and ramping operations. Regular length classification fits standard toolholders and collet chucks commonly found in job shop environments. Right-hand cutting direction is standard for conventional CNC and manual vertical milling setups.

Key Features

• M42 cobalt HSS construction for extended tool life in ferrous and high-temperature alloys
• Four flutes with 30-degree right-hand spiral helix for smooth chip evacuation and finish quality
• Centercutting design enables direct plunge entry and pocketing operations
• Bright uncoated finish allows easy visual wear inspection
• Single-end configuration with 1/2-inch straight shank fits standard collets and toolholders
• Regular length series for rigid, low-deflection cuts at standard reach

Compatibility

Designed as an OEM-style replacement or standard tooling option for 1/2-inch collet chucks, end mill holders, and Weldon shank holders used in vertical milling machines and CNC machining centers.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and locked before inserting or removing the end mill from the toolholder. Seat the shank fully in the collet or holder and torque set screws to the toolholder specification before operation. Inspect the cutting edges for chips or wear before each use and replace when flute geometry is compromised to avoid workpiece damage or tool breakage.
