Value Collection 724-0140 Roughing End Mill 5/8 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 724-0140 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers the heat and wear resistance needed when cutting tough ferrous metals and alloys. The 5/8 inch (0.625 inch) diameter tool features 4 right-hand flutes with a right-hand cutting direction and a bright, uncoated finish. With a 3/4 inch length of cut and a matching 5/8 inch shank diameter, it is suited for roughing passes where maximizing stock removal rate matters more than surface finish. Licensed machinists and tool-and-die technicians are the primary users.

This end mill is appropriate for use in vertical machining centers, knee mills, and CNC milling setups handling roughing operations on steel, stainless steel, and other hard materials. The centercutting geometry allows plunge entry where required. The M42 cobalt grade offers increased red hardness compared to standard M2 HSS, making it a dependable choice in production environments where elevated cutting temperatures are common. It ships as a single unit and is suitable for both job-shop and production-floor use.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• 4 right-hand flutes with right-hand cutting direction for efficient chip evacuation
• Centercutting capable — allows direct plunge entry into workpiece
• Bright/uncoated finish — compatible with a wide range of cutting fluids and lubricants
• Matched shank and cutter diameter (5/8 inch) for straightforward collet or end mill holder setup
• Single-end configuration — full tool length available for reach

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard 5/8 inch end mill holders, ER collet chucks, and Weldon-style holders used in vertical mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully in a properly sized collet or end mill holder and verify runout before cutting. Ensure the machine spindle is at a complete stop and locked out before changing or seating the tool. Follow applicable OSHA machine guarding requirements and shop-specific tooling change protocols.
