Value Collection 723-6734 Roughing End Mill 1/2 in Cobalt

Product Description

The VALUE COLLECTION 723-6734 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel and finished with a TiN (titanium nitride) coating, this tool handles tough ferrous and non-ferrous materials with extended tool life. It features a 0.5 inch diameter, 4 flutes, and a right-hand cutting and flute direction. The 1.625 inch length of cut and 3.625 inch overall length make it suitable for moderate-depth roughing passes. Machinists and tool-and-die professionals install this type of end mill on manual knee mills and CNC machining centers.

This roughing end mill is used in job shops, maintenance machining, and production environments where fast stock removal is prioritized over surface finish. The serrated or wave-cut flute geometry typical of roughing end mills breaks chips into smaller segments, reducing cutting forces and heat buildup. It is suited for slotting, profiling, and peripheral roughing in steel, stainless, and similar materials. The non-centercutting design means it should be fed from the side rather than plunged directly into the workpiece.

Key Features

• M42 cobalt HSS construction for heat and wear resistance in tough materials
• TiN coating extends tool life and reduces friction at the cutting edge
• 4-flute single-end configuration for efficient roughing passes
• Right-hand cut and right-hand flute direction for standard spindle operation
• Non-centercutting geometry requires side entry or pre-drilled start hole
• 0.5 inch shank diameter matches standard ER and end mill holder collets

Compatibility

Designed as a standard 1/2 inch shank roughing end mill compatible with any milling machine or machining center equipped with an appropriate end mill holder or collet chuck sized for a 0.5 inch shank.

Installation Notes

Install this end mill using a properly sized collet or end mill holder; ensure the shank is fully seated and the holder is torqued per the machine tool manufacturer specification. Power down and lock out the spindle before changing tooling. Verify runout with a dial indicator after installation to avoid premature tool wear. Because this is a non-centercutting end mill, always enter the workpiece from the side or from a pre-drilled hole.
