Value Collection 724-3113 Roughing End Mill 1/2 in Cobalt

Product Description

The VALUE COLLECTION 724-3113 is a single-end roughing end mill designed for aggressive material removal in ferrous and non-ferrous machining applications. Built from M42 cobalt high-speed steel with a TiN (titanium nitride) coating, this tool delivers improved wear resistance and heat tolerance compared to standard HSS tooling. The 1/2 inch cutting diameter and 4-flute configuration make it well suited for roughing passes where maximizing stock removal per pass is the priority. It weighs 0.02 pounds and is a right-hand cut with right-hand flute direction.

This end mill is used in milling machines, knee mills, and CNC machining centers for roughing operations on steel, cast iron, and similar materials. The single-end design is standard for general shop use, and the 1/2 inch shank diameter fits ER collets, end mill holders, and set-screw holders commonly used in both manual and CNC setups. It is installed and operated by machinists and tool and die professionals in job shop, production, and maintenance environments.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance over standard M2 HSS
• TiN coating extends tool life and reduces friction at the cutting edge
• 4-flute geometry optimized for roughing passes and high metal removal rates
• Right-hand cut and right-hand flute direction for conventional milling setups
• 1 inch length of cut with 3 inch overall length for reach in standard workholding
• Non-center-cutting design — requires a pre-drilled hole or side-entry path for plunge moves

Compatibility

Designed as a standard 1/2 inch shank roughing end mill compatible with ER collet chucks, end mill holders, and set-screw style tool holders accepting a 1/2 inch shank diameter.

Installation Notes

Installation is performed by a machinist using appropriate toolholding equipment such as an ER collet or end mill holder torqued per the toolholder manufacturer specifications. Ensure the machine spindle is fully stopped and the machine is powered down before changing tooling. Because this end mill is not center-cutting, do not use it for direct plunge entry into solid material — use a ramp or helical entry path or begin from an existing hole. Verify runout with a dial indicator after seating the tool to maintain dimensional accuracy and extend tool life.
