Value Collection 724-2239 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The VALUE COLLECTION 724-2239 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the heat resistance and edge retention needed for cutting ferrous and non-ferrous metals. The mill features a 1-inch cutting diameter, a 2-inch length of cut, and a 3/4-inch shank diameter, with 5 flutes configured for right-hand cutting and right-hand flute direction. This tool is installed by machinists and tool-and-die professionals working on manual or CNC milling machines.

This roughing end mill is suited for roughing passes on steel, stainless steel, and other tough alloys where rapid stock removal is the priority. The 5-flute geometry provides a balance between chip evacuation and surface finish during heavy cuts. With a 4-1/4-inch overall length and a non-center-cutting design, it is intended for side milling, slotting, and profiling operations where plunge cutting is not required. Typical applications include job shop work, production milling, and toolroom use on both manual knee mills and CNC machining centers.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance over standard M2 tooling
• 5-flute configuration supports efficient chip load and surface finish in roughing passes
• Bright, uncoated finish suitable for use with or without cutting fluid
• Right-hand cut and right-hand spiral flute direction for standard spindle operation
• Non-center-cutting geometry designed for side milling and profiling, not plunge entry
• 3/4-inch shank diameter fits standard ER and end mill holders

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines accepting a 3/4-inch shank end mill holder in single-end roughing configurations.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a properly sized collet or end mill holder, and verify runout with a dial indicator before beginning a cut. Do not use this tool for plunge cutting, as it is a non-center-cutting design.
