Value Collection 724-2185 Roughing End Mill 3/4 in Cobalt

Product Description

The VALUE COLLECTION 724-2185 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 metals and hard alloys where standard HSS tooling falls short. The 3/4-inch diameter cutter features 4 flutes with a right-hand cutting and flute direction, a 1.625-inch length of cut, and a 3.75-inch overall length. The bright, uncoated finish keeps costs down for shops that resharpen tooling regularly. This end mill is suited for roughing passes where maximizing chip evacuation and material removal rate takes priority over surface finish.

This roughing end mill is used in manual and CNC vertical milling centers, knee mills, and machining centers for roughing operations on steel, stainless steel, cast iron, and similar materials. The 4-flute, right-hand helix geometry balances cutting aggressiveness with chip clearance. It is a single-end tool, meaning it is re-ground from the cutting end only. Machinists and tool-and-die shops running production or job-shop work will find this geometry well-suited to roughing cavities, slots, and profiles before a finishing pass.

Key Features

• M42 cobalt HSS construction for heat and wear resistance in tough materials
• 3/4-inch diameter with matching 3/4-inch shank for direct collet or end mill holder mounting
• 4-flute right-hand cutting geometry optimized for roughing passes
• 1.625-inch length of cut and 3.75-inch overall length for standard-depth applications
• Bright, uncoated finish compatible with regrinding and re-sharpening
• Non-centercutting design — requires a pre-drilled hole or ramping entry for plunge applications

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard 3/4-inch collets, end mill holders, and milling chucks used in vertical milling machines and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Secure the 3/4-inch shank in a properly sized collet or end mill holder and torque the retention device per the spindle manufacturer's guidelines. Confirm the machine spindle is fully stopped and locked out before tool changes. Because this is a non-centercutting end mill, do not plunge directly into solid material — use a pre-drilled entry point or a ramping toolpath.
