Value Collection 724-4257 Roughing Finishing End Mill

Product Description

The VALUE COLLECTION 724-4257 is a single-end, 6-flute roughing finishing end mill designed for material removal and surface finishing in a single tool. Constructed from M42 cobalt high-speed steel with a bright/uncoated finish, it handles tough ferrous and non-ferrous metals where heat resistance and edge retention matter. The 1-inch mill diameter pairs with a 1-inch Weldon flat shank for secure, slip-resistant clamping in compatible tool holders. A 30-degree helix angle promotes smooth chip evacuation and reduces chatter during aggressive cuts. This end mill is intended for use by machinists and tool-and-die professionals in milling operations requiring both roughing and finishing passes.

This end mill is suited for vertical milling machines, horizontal mills, and machining centers in job shop, production, and maintenance environments. The 6-flute geometry increases feed rates and improves surface finish compared to lower-flute-count tools, making it appropriate for finishing passes on steel, stainless, and similar hard materials. The Weldon flat shank provides positive engagement with set-screw style tool holders, reducing pullout risk during heavy cuts. It is a non-centercutting design and should not be used for plunge cutting operations.

Key Features

• M42 cobalt construction for heat resistance and edge durability in hard materials
• 6-flute design supports higher feed rates and improved surface finish
• 30-degree helix angle promotes efficient chip evacuation and reduced chatter
• Weldon flat shank ensures positive set-screw engagement and minimizes pullout
• Bright/uncoated finish suitable for use with cutting fluid in ferrous applications
• Single-end, square end geometry for shoulder milling and finishing operations

Compatibility

Designed as a standard-shank roughing finishing end mill compatible with 1-inch bore, set-screw style Weldon tool holders used on vertical and horizontal milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Secure the Weldon flat against the tool holder set screw to the holder manufacturer's specified torque using the appropriate hex key. Confirm runout with a dial indicator before beginning the cut. Do not use this tool for plunge or slot entry cuts, as it is a non-centercutting design.
