Value Collection 723-5913 Roughing End Mill 2 in 8 Flutes Cobalt

Product Description

The VALUE COLLECTION 723-5913 is a single-end roughing end mill designed for aggressive material removal in milling operations. Machined from M42 cobalt high-speed steel, it delivers strong heat and wear resistance during heavy-duty cuts. The 2-inch diameter tool features 8 flutes with a right-hand cutting and right-hand flute direction, producing a chip-breaking action that reduces cutting forces and extends tool life. The bright, uncoated finish keeps the surface clean for inspection and is suitable for general-purpose roughing applications. This end mill is installed and operated by machinists and toolroom professionals on vertical and horizontal milling machines and machining centers.

This roughing end mill is suited for roughing passes on ferrous and non-ferrous materials where high stock removal rates are required before a finishing pass. With an 8-inch length of cut and an overall length of 11.75 inches, it is built for deep-pocket and extended-reach roughing work. The 2-inch shank diameter matches the 2-inch mill diameter, providing rigid tool holding in standard end mill holders or collet chucks. It is not centercutting and should not be used for plunge cuts directly into solid material.

Key Features

• M42 cobalt HSS construction for elevated heat resistance during heavy roughing cuts
• 8-flute geometry produces chip-breaking action that reduces cutting pressure and vibration
• 2-inch diameter with a matching 2-inch shank for rigid, concentric tool holding
• 8-inch length of cut supports deep-pocket and extended-reach roughing operations
• Right-hand cutting direction with right-hand flute spiral — standard compatibility with conventional milling setups
• Bright uncoated finish — no coating degradation risk in high-heat environments
• Single-end design — tool is replaced rather than reversed when worn

Compatibility

Designed for use in standard 2-inch end mill holders, shell mill arbors, or collet chucks that accept a 2-inch straight shank. Suitable for use on vertical and horizontal milling machines and CNC machining centers equipped to run large-diameter roughing tools.

Installation Notes

A licensed machinist or toolroom technician should install and set this end mill following shop safety protocols. Power down and lock out the machine spindle before mounting or removing the tool. Verify shank and holder cleanliness and proper torque on the retention hardware per the machine tool manufacturer specifications before running. Because this tool is not centercutting, always enter the workpiece from the side or use a pre-drilled pilot hole — never plunge directly into solid stock.
