Value Collection 724-0308 Roughing End Mill 1-1/4 in 6 Flute

Product Description

The VALUE COLLECTION 724-0308 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright/uncoated finish, it delivers the heat resistance and edge hardness needed for cutting ferrous and difficult-to-machine materials. The 1.25-inch diameter cutter features 6 flutes configured in a right-hand cutting and right-hand flute direction, providing efficient chip evacuation during heavy roughing passes. The tool is centercutting, allowing plunge cuts where required. With a 3-inch length of cut and 5.5-inch overall length, it suits deep-pocket and slot roughing operations on manual mills and CNC machining centers alike.

This roughing end mill is suited for production and job-shop environments where rapid stock removal is the priority before a finishing pass. The 6-flute geometry reduces chatter at higher feed rates compared to lower-flute-count roughers, making it a practical choice for steel, stainless, and alloy materials. The 1.25-inch shank diameter matches the cutter diameter, providing consistent clamping in standard ER collet chucks, end mill holders, or hydraulic toolholders of the appropriate bore size.

Key Features

• M42 cobalt steel construction for elevated heat and wear resistance
• 6-flute design supports higher feed rates and reduced vibration during roughing
• Centercutting geometry enables direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute direction for standard spindle operation
• Bright/uncoated finish suitable for use with flood coolant or cutting oil
• Single-end configuration with 3-inch length of cut for deep-pocket work

Compatibility

Designed as a standard-shank roughing end mill with a 1.25-inch shank diameter, compatible with any end mill holder, ER collet system, or hydraulic chuck bored to 1.25 inches on manual knee mills or CNC vertical machining centers.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in an e-stop or tool-change state. Ensure the toolholder bore and shank are clean and free of chips or coolant residue before seating the tool. Tighten the retention mechanism to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates edge wear on cobalt tools.
