Value Collection 723-3239 Square End Mill 2 in 6 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3239 is a cobalt square end mill designed for milling operations that demand heat resistance and durability beyond standard high-speed steel tooling. Built from M42 cobalt material, this single-end tool runs a 2 inch cutting diameter with a 2 inch length of cut and a 6-flute spiral geometry at a 30-degree helix angle. The 1.25 inch shank diameter and 4.5 inch overall length suit it to standard vertical milling machines and CNC machining centers. It is center-cutting, enabling plunge entry as well as peripheral and face milling in a single tool. Right-hand cut and right-hand flute orientation are standard configuration.

This end mill fits general-purpose milling applications including slotting, profiling, and pocketing in ferrous and non-ferrous materials where elevated cutting temperatures are a factor. The M42 cobalt grade provides added red-hardness compared to M2, making it a practical choice for tougher alloys, stainless steel, and work-hardening materials. The bright uncoated finish keeps regrinding straightforward. Machinists and tool-and-die professionals running conventional or CNC mills will find this a dependable production tool for medium to heavy stock removal passes.

Key Features

• M42 cobalt construction for elevated heat resistance and tool life in tough materials
• 6-flute spiral geometry with 30-degree helix for efficient chip evacuation and smooth finish
• Center-cutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute — standard configuration for most vertical and CNC mills
• Bright uncoated finish simplifies regrinding and recoating
• No chipbreaker, no variable helix — straightforward geometry for predictable performance

Compatibility

Designed as an OEM-style replacement or direct substitute square end mill for machining centers and vertical milling machines accepting a 1.25 inch shank diameter toolholder.

Installation Notes

Installation requires a compatible toolholder or collet rated for a 1.25 inch shank. Secure the shank to full engagement depth per toolholder manufacturer guidelines before operation. Power down and lock out the spindle before changing or inspecting the tool. Follow all applicable shop safety standards and machine manufacturer specifications for feeds, speeds, and depth of cut when running cobalt tooling.
