Value Collection 724-6433 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 724-6433 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, this tool handles tough ferrous and non-ferrous metals with greater heat and wear resistance than standard HSS tooling. A TiN (titanium nitride) coating further extends tool life by reducing friction and increasing surface hardness. The 3-flute geometry with a high helix angle promotes efficient chip evacuation while maintaining a strong core. Center-cutting capability allows plunge entry into a workpiece. At 0.375 inches in diameter with a 0.75-inch length of cut and 2.5-inch overall length, it fits standard toolholders for vertical or horizontal milling machines.

This end mill is suited for roughing passes in job shop, production machining, and maintenance repair environments. It excels in applications requiring fast stock removal on alloy steels, tool steels, and similar hard materials. The right-hand cut and right-hand spiral flute direction are compatible with conventional CNC machining centers and manual knee mills. The 3/8-inch shank diameter fits standard collets, shrink-fit holders, and end mill adapters common in most shops. Machinists and tool-and-die tradespeople are the primary installers and users of this tooling.

Key Features

• M42 cobalt construction for improved heat resistance over standard M2 HSS
• TiN coating reduces friction and extends cutting edge life
• 3-flute, high-helix design promotes chip clearing during roughing cuts
• Center-cutting geometry allows direct plunge milling
• Right-hand cut and right-hand flute direction for standard spindle operation
• Single-end design with 3/8-inch shank for broad toolholder compatibility

Compatibility

Designed as a standard 3/8-inch single-end roughing end mill compatible with collet chucks, shrink-fit holders, and end mill adapters accepting a 3/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended insertion depth in the toolholder and verify runout before cutting. Follow the machine manufacturer and tooling guidelines for appropriate feeds, speeds, and depth of cut for the workpiece material.
