Value Collection 724-4056 Roughing Finishing End Mill

Product Description

The VALUE COLLECTION 724-4056 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 alloys and stainless steels where standard HSS tooling falls short. The 5/16 inch cutting diameter and 4-flute configuration deliver efficient chip evacuation during roughing passes while leaving a finish suitable for many applications. A 30-degree helix angle supports smooth cutting action and reduces chatter. This end mill is used by machinists and tool-and-die professionals working on manual mills and CNC machining centers.

This end mill suits general metalworking applications where a single tool must rough and finish in sequence without a tool change. The 1-1/8 inch length of cut accommodates moderate-depth pockets and slots. The 3/8 inch Weldon flat shank provides positive drive retention in standard end mill holders, reducing pullout risk under load. Right-hand cutting and right-hand flute direction match conventional milling setups. Single-end configuration means the tool is replaced when worn rather than reversed.

Key Features

• M42 cobalt construction for heat resistance and tool life in ferrous and hard materials
• 4-flute square end geometry for roughing and finishing in one pass
• 30-degree helix angle reduces chatter and improves chip flow
• Weldon flat shank provides positive drive retention and reduces pullout
• Bright uncoated finish suitable for use with cutting fluids on a broad range of materials
• Right-hand cut and flute direction for standard milling setups

Compatibility

Designed for use in standard end mill holders and collet chucks accepting a 3/8 inch Weldon flat shank, compatible with manual knee mills and CNC vertical machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the Weldon flat shank in a properly sized end mill holder and tighten set screws against the flat to prevent pullout. Verify spindle speed and feed rate against published data for the workpiece material before cutting. Inspect the tool for chips or cracks before each use and replace when cutting edges show wear.
