Value Collection 724-3155 Roughing End Mill 5/8 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 724-3155 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suited to harder workpiece materials where standard HSS tooling falls short. The cutter measures 0.625 inches in diameter with a 2.5-inch length of cut and an overall length of 4.625 inches. A TiN coating reduces friction and extends tool life. Four right-hand flutes with a right-hand cutting direction provide efficient chip evacuation during roughing passes. This tool is used by machinists and tool-and-die professionals in manual and CNC milling setups.

The 724-3155 is suited for roughing operations on ferrous and non-ferrous materials in job shop, production, and maintenance machining environments. Its 0.625-inch shank diameter matches standard 5/8-inch collets and end mill holders. The non-centercutting geometry means this mill is intended for peripheral cuts and side milling rather than plunge entry. It is a practical choice for roughing passes before a finish end mill is applied, particularly when cutting alloy steels, stainless, or other tough materials that benefit from cobalt tooling.

Key Features

• M42 cobalt HSS construction resists heat buildup during aggressive cuts
• TiN coating reduces friction and extends cutting edge life
• 4 right-hand flutes with right-hand cutting direction for efficient chip removal
• 2.5-inch length of cut handles deep roughing passes
• Non-centercutting design optimized for peripheral and side milling
• Single-end configuration with 0.625-inch shank for direct holder fitment

Compatibility

Designed for use in standard 5/8-inch end mill holders, collet chucks, and milling machine spindles accepting a 0.625-inch shank diameter.

Installation Notes

Installation is performed by machinists using a standard end mill holder or collet rated for the 0.625-inch shank. Ensure the milling machine spindle is fully stopped and locked before mounting or removing the tool. Verify runout with a dial indicator after seating to minimize premature edge wear. This is a non-centercutting tool and must not be used for plunge drilling operations.
