Value Collection 724-1125 Roughing End Mill 1/2 in Cobalt

Product Description

The VALUE COLLECTION 724-1125 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a TiN (titanium nitride) coating, it delivers heat and wear resistance suited for interrupted cuts and harder workpiece materials. The cutter measures 0.5 inches in diameter with a 2.5-inch length of cut and a 4.5-inch overall length. Four right-hand flutes with a right-hand cutting direction provide efficient chip evacuation during roughing passes. This tool is used by machinists and tool-and-die professionals on manual and CNC milling machines.

This roughing end mill is suited for roughing operations on ferrous and non-ferrous metals where high stock removal rates are required before finishing passes. The center-cutting design allows for plunge entry, adding versatility in setup. The 0.5-inch shank diameter matches standard R8, ER, and side-lock toolholders commonly found in vertical milling machine spindles. It is a single-end tool, so the full shank remains available for gripping depth.

Key Features

• M42 cobalt HSS construction for improved hardness and heat resistance over standard M2 HSS
• TiN coating reduces friction and extends tool life in ferrous materials
• Center-cutting geometry allows direct plunge milling without pre-drilling
• Right-hand cut, right-hand helix for standard spindle rotation and upward chip flow
• 0.5-inch shank diameter fits common milling toolholders without adapters
• 2.5-inch length of cut accommodates deeper shoulder and slot roughing passes

Compatibility

Designed as a direct-fit roughing end mill for any milling machine or machining center accepting a 0.5-inch shank toolholder, including R8 collets, ER collet chucks, and Weldon-style side-lock holders.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and the spindle locked before seating or removing the tool. Ensure the shank is clean and free of chips or burrs before inserting into the toolholder, and verify runout with a dial indicator after tightening. Follow the machine tool manufacturer's torque specifications for the toolholder type in use. Do not exceed the recommended depth of cut for roughing passes based on workpiece material and machine rigidity.
