Value Collection 724-3077 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 724-3077 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiN (titanium nitride) coating, it delivers elevated heat and wear resistance compared to standard HSS tooling. The 3/8 inch diameter cutter features 4 right-hand flutes with a right-hand cutting direction, a 3/4 inch length of cut, and a 2-1/2 inch overall length. This tool is sized for manual mills, knee mills, and CNC machining centers where controlled roughing passes are required before finishing.

This roughing end mill is suited for use on ferrous and non-ferrous metals in light industrial and job-shop environments. It is a non-centercutting design, meaning it is intended for side milling and peripheral cuts rather than plunge entry. Machinists and tool-and-die professionals use this style of end mill for slotting, profiling, and heavy shoulder milling where chip evacuation and tool life under interrupted cuts are priorities.

Key Features

• M42 cobalt HSS construction for improved hot hardness and wear resistance over standard M2 HSS
• TiN coating reduces friction and extends tool life in ferrous materials
• 4-flute, right-hand spiral geometry for efficient chip evacuation during roughing passes
• 3/8 inch shank diameter matches cutter diameter for straightforward collet or end mill holder setup
• Non-centercutting design — intended for side milling and peripheral cuts, not plunge entry
• Single-end configuration at 2-1/2 inch overall length for use in standard tool holders

Compatibility

Designed as a standard roughing end mill for use in 3/8 inch collets, end mill holders, or set-screw holders on manual knee mills and CNC machining centers.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with speeds, feeds, and toolholder torque requirements for cobalt end mills. Secure the 3/8 inch shank in a clean, properly sized collet or end mill holder before use, and verify runout with a dial indicator when precision is critical. Do not use this tool for plunge cutting, as it is a non-centercutting design. Always set spindle speed and feed rate appropriate for the workpiece material and consult tooling manufacturer data for recommended cutting parameters.
