Value Collection 723-5844 Roughing End Mill 1-1/4 in Cobalt

Product Description

The VALUE COLLECTION 723-5844 is a single-end roughing end mill designed for aggressive material removal in milling operations. Constructed from M42 cobalt high-speed steel, this tool delivers heat resistance and edge retention during heavy-duty cuts. It features a 1.25-inch mill diameter with a matching 1.25-inch shank diameter and six flutes configured for right-hand cutting with right-hand flute direction. The 6-inch length of cut and 8.5-inch overall length make it well suited for deep-pocket and high-stock-removal applications. The bright, uncoated finish keeps the tool ready to run as-received. Licensed machinists, tool-and-die makers, and CNC operators are the primary installers and users.

This roughing end mill is used in vertical machining centers, knee mills, and CNC milling machines for roughing passes on ferrous and non-ferrous materials. Its cobalt M42 construction handles harder workpiece materials and elevated cutting temperatures better than standard high-speed steel. The six-flute geometry provides a high feed rate capability while breaking chips efficiently, making it a common choice for removing large amounts of stock before a finishing pass.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• Six-flute design supports higher feed rates and efficient chip evacuation
• 1.25-inch mill diameter with matching 1.25-inch shank for straight-shank holders
• 6-inch length of cut accommodates deep-pocket roughing operations
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Bright, uncoated finish — no additional prep required before use

Compatibility

Designed for use in standard straight-shank end mill holders and collet chucks accepting a 1.25-inch shank diameter, commonly found on vertical machining centers and manual knee mills.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated in the collet or end mill holder and that set screws or collet nuts are secured to the manufacturer specification of the toolholder. This end mill is not centercutting — do not plunge directly into solid material; use a ramping or helical entry path instead.
