Value Collection 723-5721 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 723-5721 is a single-end roughing end mill designed for aggressive material removal in milling operations. Manufactured from M42 cobalt high-speed steel, this tool handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 3/8 inch diameter body carries four flutes with a right-hand cutting and right-hand flute direction. The bright, uncoated finish is standard for cobalt tooling used in applications where coating adhesion is not required. It is installed by machinists and tool-and-die technicians on vertical mills, CNC machining centers, and manual knee mills.

This end mill is suited for roughing passes in ferrous metals, stainless steel, and high-temperature alloys where heat resistance and edge toughness are priorities. The 3/4 inch length of cut accommodates standard-depth roughing operations, while the 2-1/2 inch overall length fits common toolholders without excessive overhang. The non-centercutting geometry means it is intended for peripheral milling and slotting entries that do not require plunge cutting. Single-end construction concentrates tool mass at the cutting end for stability during heavy chip-load operations.

Key Features

• M42 cobalt construction for superior heat and wear resistance over standard M2 HSS
• Four-flute geometry balances chip evacuation with surface finish on roughing passes
• Right-hand cut and right-hand helix for conventional milling setups
• Bright, uncoated finish compatible with cutting fluid use across a range of materials
• Non-centercutting design optimized for peripheral and slot-entry milling
• Single-end configuration with 3/8 inch shank diameter for standard collet and endmill holder fitment

Compatibility

Designed as an OEM-style replacement roughing end mill for use in standard 3/8 inch collets, endmill holders, and milling chucks on vertical mills and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing tooling. Seat the shank fully into the collet or endmill holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before commencing cuts, as excessive runout accelerates flute wear on cobalt tooling.
