Value Collection 724-1173 Roughing End Mill 3/4 in Cobalt

Product Description

The VALUE COLLECTION 724-1173 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel, this end mill handles tough ferrous metals and heat-resistant alloys where standard HSS tooling falls short. A titanium nitride (TiN) coating reduces friction and extends cutting life. With a 3/4 inch cutting diameter, 4 flutes, and a 3/4 inch length of cut, it delivers controlled chip evacuation and reduced chatter during roughing passes. Right-hand cutting and right-hand flute geometry are standard. Weighing 0.5 pounds, it is a solid, full-size tool suited for production and job-shop environments alike.

This end mill is used in vertical and horizontal milling machines, knee mills, and CNC machining centers performing roughing operations on steel, stainless, cast iron, and similar materials. The 3/4 inch shank diameter fits standard R8, CAT, BT, and side-lock toolholders sized for 3/4 inch shanks. It is center-cutting, so plunge milling operations are supported. Machinists, tool-and-die makers, and CNC operators in production shops are the primary users. It is a single-end tool, meaning once the cutting end is worn, the tool is replaced rather than flipped.

Key Features

• M42 cobalt steel construction for heat and wear resistance in tough alloys
• TiN coating reduces cutting friction and extends tool life
• 4-flute geometry for efficient chip removal during roughing passes
• Center-cutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand helix for standard milling machine spindle compatibility
• 3/4 inch shank diameter fits common milling toolholders

Compatibility

Designed as a direct-fit roughing end mill for milling machines and CNC machining centers equipped with 3/4 inch toolholders, including R8, CAT, BT, and side-lock holder styles.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before inserting or removing the end mill from the toolholder. Ensure the shank is fully seated and the drawbar or retention knob is properly torqued per the machine and toolholder manufacturer specifications. Inspect the collet or holder for wear or runout before use, as excessive runout accelerates tool wear and reduces cut quality.
