Value Collection 724-0248 Roughing End Mill 1 in 3 Flute Cobalt

Product Description

The VALUE COLLECTION 724-0248 is a single-end roughing end mill designed for high-speed material removal in milling applications. Built from M42 cobalt high-speed steel with a bright uncoated finish, this tool handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. It features a 1-inch cutting diameter, a 1-inch length of cut, and a 3.5-inch overall length. The coarse-pitch flute geometry on the 3-flute design breaks chips aggressively, reducing heat buildup and cutting forces during heavy roughing passes. Machinists and tool-and-die professionals working on manual or CNC mills rely on this type of tooling for rapid stock removal before finish passes.

This end mill is suited for roughing operations on a wide range of workpiece materials, including alloy steels, stainless steels, and other materials that benefit from cobalt tooling. The 1-inch shank diameter matches the cutting diameter, making it compatible with standard ER or end mill holders with a 1-inch bore. Right-hand cut and right-hand flute direction make it a straightforward drop-in for conventional milling setups. It is appropriate for both manual knee mills and CNC machining centers in job shop, maintenance, and production environments.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance over standard M2 HSS
• Coarse-pitch, 3-flute design promotes aggressive chip evacuation during heavy roughing
• Center-cutting geometry allows plunge entry without a pre-drilled pilot hole
• Bright uncoated finish suitable for use with standard cutting fluids and oils
• Right-hand cut and right-hand helix for conventional milling compatibility
• Single-end configuration with 1-inch cutting diameter and 1-inch length of cut

Compatibility

Designed as a standard roughing end mill replacement for use in 1-inch end mill holders, collet chucks, or hydraulic holders on manual or CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing tooling. Ensure the shank is fully seated in the holder to the recommended engagement depth and that the set screw or collet is torqued using the holder manufacturer's guidelines. Inspect the cutting edges for chips or damage before each use, and match spindle speed and feed rate to the workpiece material per standard machining data references.
