Value Collection 724-2287 Roughing End Mill 1-1/4 in 6 Flute

Product Description

The VALUE COLLECTION 724-2287 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 handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 1.25-inch cutting diameter pairs with a 0.75-inch shank diameter and a 1.125-inch length of cut, giving machinists a rigid, capable tool for roughing passes on manual mills and CNC machining centers. With 6 flutes and right-hand cutting and flute direction, it clears chips efficiently during heavy stock removal.

This roughing end mill is suited for job shops, tool rooms, and production environments where operators need a reliable cobalt rougher for ferrous alloys, stainless steel, and heat-resistant materials. The single-end design makes it a straightforward drop-in for standard end mill holders and collet chucks with a 3/4-inch bore. It is not center-cutting, so plunge milling is not the intended use. Peripheral and slot roughing passes are the primary application. The tool is sold individually and is a common choice for prototype work, mold roughing, and first-pass profiling.

Key Features

• M42 cobalt steel construction for improved red hardness and wear resistance over standard M2 HSS
• 6-flute geometry promotes efficient chip evacuation during heavy roughing cuts
• 1.25-inch cutting diameter with 1.125-inch length of cut for substantial depth of engagement
• 0.75-inch shank diameter fits standard end mill holders and collet chucks
• Right-hand cut and right-hand helix for conventional and climb milling compatibility
• Bright, uncoated finish — no coating to spall or delaminate in interrupted cuts

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for manual or CNC milling machines accepting a 3/4-inch shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling change procedures. Ensure the machine spindle is fully stopped and locked before installing or removing the tool. Seat the shank fully into the holder and torque the set screw or collet nut per the holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates tool wear and reduces surface finish quality.
