Value Collection 724-4143 Roughing Finishing End Mill

Product Description

The VALUE COLLECTION 724-4143 is a cobalt roughing finishing end mill designed for aggressive material removal followed by semi-finish passes in a single tool. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention in tough ferrous materials. The 5/8-inch diameter with a matching 5/8-inch Weldon Flat shank provides a secure, anti-pullout grip in the spindle. A 30-degree helix angle promotes smooth chip evacuation, and the bright uncoated finish suits applications where coating interaction with the workpiece material is a concern. Licensed machinists and tool-and-die professionals use this style of end mill for roughing slots, profiling, and finishing cuts without a tool change.

This end mill is suited for milling operations on steel, cast iron, and other ferrous alloys in manual knee mills, CNC machining centers, and mill-drill setups. The square end geometry handles peripheral and side milling. With a 1-1/4-inch length of cut and 3-3/8-inch overall length, it covers standard-depth slotting and profiling applications in job shop, toolroom, and production environments. The right-hand flute direction and right-hand cutting orientation are compatible with conventional spindle rotation on standard vertical milling machines.

Key Features

• M42 cobalt construction for elevated heat resistance and edge retention in ferrous materials
• 4-flute configuration supports both roughing and finishing passes in a single tool
• 5/8-inch Weldon Flat shank provides anti-pullout security in side-lock holders
• 30-degree helix angle promotes efficient chip evacuation during slotting and profiling
• Square end geometry for peripheral milling, side milling, and square-shoulder work
• Bright uncoated finish suitable for dry cutting or use with coolant on ferrous stock

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 5/8-inch side-lock or Weldon Flat end mill holders used in vertical machining centers and knee mills.

Installation Notes

Installation requires a 5/8-inch side-lock holder or Weldon Flat collet rated for the shank diameter. Power down and lock out the spindle before inserting or removing end mills. Verify holder set screw torque per the holder manufacturer specification and confirm runout with a dial indicator before cutting. This tool is not center-cutting and should not be plunged axially into solid material.
