Value Collection 724-2026 Roughing End Mill Cobalt M42

Product Description

The VALUE COLLECTION 724-2026 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting ferrous metals, stainless steel, and high-temperature alloys. The 0.25 inch diameter body pairs with a 0.375 inch shank, providing rigidity on lighter-duty setups. Three flutes in a right-hand cutting and right-hand flute configuration move chips efficiently during roughing passes. The bright, uncoated finish keeps the tool serviceable across standard shop environments. Machinists and toolroom technicians use this mill for roughing operations before finish passes.

This end mill suits vertical machining centers, knee mills, and manual milling machines running ferrous and non-ferrous stock. The 0.875 inch length of cut accommodates moderate-depth slotting and profiling operations. The non-center-cutting design means it is intended for side milling, peripheral profiling, and plunge moves only when pre-drilled entry is available. It is a practical choice for job shops, maintenance machining, and production toolrooms needing a reliable roughing tool in a small diameter.

Key Features

• M42 cobalt high-speed steel construction for extended tool life in tough materials
• 3 flutes with right-hand cut and right-hand helix for efficient chip evacuation during roughing
• 0.375 inch shank diameter provides a stable grip in standard ER or side-lock holders
• Bright, uncoated finish — compatible with most cutting fluids and coolants
• Single-end configuration — full 2.6875 inch overall length maximizes reach in the holder
• Non-center-cutting geometry — optimized for peripheral and slot milling, not direct plunge entry

Compatibility

Designed as a standard single-end roughing end mill with a 0.375 inch shank, compatible with conventional ER collet chucks, side-lock holders, and milling chucks sized for 0.375 inch shanks on vertical machining centers and manual knee mills.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures for milling equipment. Ensure the machine spindle is fully stopped and the power is isolated before loading or changing any end mill. Confirm the collet or holder bore matches the 0.375 inch shank diameter and that the tool is seated to the correct gauge length before tightening. Because this tool is not center-cutting, do not plunge directly into solid material without a pre-drilled or pre-milled entry point.
