Value Collection 724-2116 Roughing End Mill 1/2 in Cobalt

Product Description

The VALUE COLLECTION 724-2116 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it measures 0.5 inches in diameter with a 1.25-inch length of cut and a 3.25-inch overall length. The four-flute, right-hand cutting and flute geometry channels chips efficiently while the cobalt composition resists heat and wear under heavy feed rates. This tool is suited for machinists and tool-and-die professionals running manual or CNC milling machines where roughing passes demand durability over fine surface finish.

This roughing end mill is intended for use on ferrous and non-ferrous metals where rapid stock removal is the priority before a finishing pass. The 0.5-inch shank diameter fits standard ER collet chucks, end mill holders, and side-lock arbors commonly found in knee mills and machining centers. It is not center-cutting, so it is not suited for plunge milling. The right-hand flute direction and right-hand cut make it compatible with standard spindle rotation on conventional milling setups.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance compared to standard M2 tooling
• Four flutes with right-hand cut and right-hand helix for efficient chip evacuation on roughing passes
• Bright, uncoated finish suitable for use with cutting fluid on a wide range of materials
• 0.5-inch shank diameter matches the 0.5-inch mill diameter for direct collet or end mill holder mounting
• Single-end design with 1.25-inch length of cut and 3.25-inch overall length
• Not center-cutting — designed for peripheral and slot milling, not plunge entry

Compatibility

Designed as a standard 0.5-inch shank roughing end mill compatible with ER32 collet chucks, end mill holders, and side-lock arbors accepting a 0.5-inch straight shank on manual knee mills and CNC vertical machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines for tool holding and runout tolerance. Power down and lock out the spindle before seating or removing the end mill from any holder. Ensure the shank is clean and free of chips or burrs before tightening the collet or set screw to the holder manufacturer's specified procedure. Verify tool projection and runout with a dial indicator before beginning a cut.
