Value Collection 724-4008 Roughing Finishing End Mill

Product Description

The VALUE COLLECTION 724-4008 is a cobalt roughing finishing end mill designed for material removal and surface finishing in a single tool. Built from M42 cobalt high-speed steel, it handles tough ferrous and exotic materials where standard HSS tooling falls short. The 3-flute, square-end geometry with a 30-degree helix angle balances chip evacuation and surface finish. The 3/16 inch cutting diameter and 3/8 inch Weldon flat shank make it well-suited for precision milling operations on manual mills and CNC machining centers. It is a single-end tool with right-hand flute direction and right-hand cutting action, weighing 0.02 pounds.

This end mill is used in job shops, tool rooms, and production environments where machinists need to rough and finish in fewer passes. It is suited for slotting, profiling, and light pocketing in steel, stainless, and high-temperature alloys. The Weldon flat shank provides a secure, slip-resistant hold in standard end mill holders and collet chucks. The bright uncoated finish means no coating concerns when machining materials sensitive to coating adhesion or when re-sharpening is planned.

Key Features

• M42 cobalt construction for heat resistance and tool life in tough materials
• 3-flute square end geometry combines roughing chip clearance with a clean square shoulder finish
• 30-degree helix angle promotes efficient chip flow and reduces cutting forces
• 3/8 inch Weldon flat shank provides positive anti-rotation seating in the holder
• Bright uncoated finish compatible with re-sharpening and coating-sensitive applications
• Single-end, right-hand cut configuration for standard milling setups

Compatibility

Designed as a standard single-end roughing finishing end mill with a 3/8 inch Weldon flat shank, compatible with end mill holders and milling chucks sized for 3/8 inch straight shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing the end mill. Seat the Weldon flat against the set screw in the holder to prevent axial pullout during cutting. Verify tool projection and runout before beginning the cut.
