Value Collection 724-4146 Roughing End Mill 5/8 in Cobalt

Product Description

The VALUE COLLECTION 724-4146 is a roughing finishing end mill designed for aggressive material removal in milling operations. Made from M42 cobalt high-speed steel, this tool handles tough ferrous and non-ferrous metals where standard HSS tooling wears prematurely. It features a 5/8 inch diameter, four flutes, a square end geometry, and a 30-degree helix angle for efficient chip evacuation. The bright/uncoated finish suits a range of materials without the added cost of coatings. Machinists and toolroom operators install this end mill in vertical mills, CNC machining centers, and knee mills for roughing passes that require controlled stock removal.

This end mill is suited for roughing and semi-finishing operations in job shop, production machining, and toolroom environments. The 1-5/8 inch length of cut and 3-3/4 inch overall length make it practical for moderate-depth pocket milling, slotting, and peripheral cuts. The 5/8 inch Weldon flat shank provides positive drive and resists pullout in end mill holders equipped with a set screw. Right-hand flute direction and right-hand cutting orientation are standard for conventional vertical milling setups.

Key Features

• M42 cobalt construction for heat resistance and extended tool life in tough materials
• Four right-hand flutes with 30-degree helix angle for efficient chip flow
• Square end geometry for shoulder milling, slotting, and step machining
• Weldon flat shank provides secure, positive drive in standard end mill holders
• Bright/uncoated finish compatible with a wide range of work materials
• Single-end design for straightforward replacement when cutting edges are spent

Compatibility

Designed for use in standard end mill holders and Weldon-style tool holders accepting a 5/8 inch shank diameter. Suitable for vertical mills, knee mills, and CNC machining centers configured for right-hand cutting tools.

Installation Notes

Installation is performed by machinists or toolroom personnel. Secure the Weldon flat shank in a matching end mill holder and tighten the set screw against the flat to prevent rotation and pullout. Verify spindle speed and feed rate are appropriate for the work material and depth of cut before engaging the tool. Inspect the collet or holder for runout and wear before mounting to protect tool life and surface finish quality.
