Value Collection 724-5140 Roughing End Mill 5/8 in Cobalt

Product Description

The VALUE COLLECTION 724-5140 is a roughing-finishing end mill designed for aggressive material removal and refined surface finishing in a single tool. Built from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), it delivers extended tool life and improved wear resistance in demanding machining environments. The 5/8 inch diameter, 4-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. With a square end profile and right-hand flute direction, this end mill suits a wide range of milling operations on ferrous and non-ferrous materials. It is a single-end tool with a Weldon flat shank for secure, slip-resistant tool holder engagement.

This end mill is suited for use in vertical and horizontal milling machines where operators need a combination rougher-finisher on steel, stainless, cast iron, and similar workpiece materials. The 3/4 inch length of cut allows for moderate-depth slotting and peripheral milling passes. The 5/8 inch shank diameter matches common ER and Weldon-style tool holders found in most machine shops. It is typically installed and operated by machinists and toolroom technicians working in production or job-shop environments.

Key Features

• M42 cobalt construction for heat resistance and hardness retention at elevated cutting speeds
• TiN coating reduces friction and extends cutting edge life compared to uncoated tooling
• 4-flute, 30-degree helix geometry balances chip clearance with surface finish quality
• Weldon flat shank provides positive engagement in set-screw tool holders, preventing pullout
• Square end profile supports slotting, side milling, and shoulder milling applications
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindle rotation

Compatibility

Designed as an OEM-style replacement or equivalent for 5/8 inch roughing-finishing end mills with Weldon flat shanks used in standard milling machine tool holders accepting 5/8 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before inserting or removing the end mill from the tool holder. Ensure the Weldon flat is properly aligned with the set screw in the holder and tighten to the tool holder manufacturer torque specification. Inspect the cutting edges and coating for wear or chipping before each use and do not operate a damaged tool.
