Value Collection 723-3216 Square End Mill 3/4 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3216 is a cobalt square end mill designed for milling operations requiring durability and heat resistance beyond standard high-speed steel tooling. Built from M42 cobalt material and finished bright/uncoated, this single-end mill features a 3/4 inch cutting diameter, a 1-5/8 inch length of cut, and a 30-degree right-hand spiral helix. It is centercutting, allowing plunge cuts as well as side and peripheral milling. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers and manual knee mills for ferrous and hard-material stock removal.

This end mill is suited for general-purpose milling in job shop, production, and maintenance machining environments. The 5/8 inch shank diameter fits standard ER and side-lock toolholders commonly found in vertical and horizontal machining centers. Its regular-length geometry makes it a practical choice for face milling, slotting, profiling, and step milling on steel, stainless steel, cast iron, and similar hard materials where cobalt tooling provides an advantage over standard HSS.

Key Features

• M42 cobalt construction for improved heat and wear resistance compared to standard HSS
• 4 flutes with right-hand cut and right-hand spiral for efficient chip evacuation
• 30-degree helix angle balances cutting force and surface finish on ferrous materials
• Centercutting geometry enables direct plunge entry without a pre-drilled hole
• Bright/uncoated finish — compatible with cutting fluids and standard coolant systems
• Single-end design; regular-length series for stable reach-to-rigidity ratio

Compatibility

Designed as a general-purpose replacement or stock end mill for machining applications requiring a 3/4 inch diameter, 4-flute, single-end cobalt square end mill with a 5/8 inch shank. Part of the VCCC-C-4 series.

Installation Notes

Installation is performed by qualified machinists. Secure the 5/8 inch shank firmly in a compatible collet chuck, end mill holder, or Weldon-style side-lock holder before use. Confirm spindle speed and feed rate are appropriate for the workpiece material and depth of cut before engaging the cut. Never exceed the rated length of cut of 1-5/8 inches to avoid tool deflection or breakage.
