Value Collection 724-0278 Roughing End Mill 1-1/8 in 6 Flute

Product Description

The VALUE COLLECTION 724-0278 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 bright/uncoated finish, this cutter handles high-heat operations where standard HSS tools lose their edge. The 1.125-inch (1-1/8 inch) cutting diameter pairs with a 2.0-inch length of cut and 6 right-hand spiral flutes engineered to break chips quickly and reduce chatter during roughing passes. It is centercutting, allowing plunge entry. Machinists and tool-and-die professionals reach for this style of end mill when roughing steel, stainless, and other difficult alloys before a finishing pass.

This end mill fits standard CNC machining centers, knee mills, and manual vertical mills equipped with a 3/4-inch collet or tool holder. It is suited for roughing operations in job shops, production machining environments, and maintenance repair contexts where material needs to be removed quickly before a finish tool cleans up the surface. The 4.25-inch overall length accommodates typical setups without excessive overhang. Right-hand cutting direction is compatible with conventional right-hand spindle rotation.

Key Features

• M42 cobalt construction provides higher heat and wear resistance compared to standard M2 HSS
• 6-flute geometry increases chip load capacity and speeds up material removal on roughing passes
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Bright/uncoated finish maintains sharp edge geometry and suits a wide range of cutting fluids
• 3/4-inch shank diameter fits widely available collet chucks and end mill holders
• Single-end configuration simplifies tool changes and reduces runout concerns

Compatibility

Designed as a direct-fit roughing end mill for any milling machine or machining center that accepts a 3/4-inch shank end mill holder or collet.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the spindle before seating or removing any end mill. Seat the shank fully into the collet or holder to the recommended minimum engagement depth and torque the retention nut per the tool holder manufacturer specifications. Inspect the shank and flute condition before each use and do not exceed the manufacturer-recommended feeds and speeds for the workpiece material.
