Accupro 312672 Corner Radius End Mill 5/8 in 7 Flute

Product Description

The ACCUPRO 312672 is a solid carbide corner radius end mill designed for precision milling operations in demanding shop environments. With a 5/8 inch diameter, 7-flute geometry, and a 38-degree helix angle, it delivers smooth cutting action and excellent chip evacuation on ferrous and hardened materials. The AlCrTiN coating provides high heat resistance and surface hardness, extending tool life in high-speed and dry cutting applications. The 0.060 inch corner radius reduces stress concentration at the cutting edge, helping to prevent chipping on hardened workpieces. This tool is installed and operated by machinists and tool-and-die professionals using CNC vertical and horizontal machining centers.

This end mill is suited for profiling, slotting, and finish milling operations in steel, stainless steel, cast iron, and other hard-to-machine alloys. The single-end, non-centercutting design means it is not intended for direct plunge cutting into solid material. With a 3/4 inch length of cut and 3 inch overall length on a straight cylindrical shank, it fits standard collet and end mill holder setups in typical production and toolroom environments.

Key Features

• 7-flute solid carbide construction for rigidity and fine surface finish
• AlCrTiN coating for high heat resistance and extended tool life in dry and hard milling
• 0.060 inch corner radius reduces edge chipping on hardened materials
• 38-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Micrograin carbide grade provides superior wear resistance
• Right-hand cut and right-hand flute spiral for standard CNC machining center compatibility

Compatibility

Designed as an OEM-style replacement and production end mill for use in standard 5/8 inch straight-bore collets, end mill holders, and shrink-fit holders on CNC machining centers requiring a corner radius end mill in the HS Series.

Installation Notes

Installation should be performed by qualified machinists following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and machine is in a safe state before changing tooling. Seat the shank fully in the holder and torque retention screws or collet nuts to the holder manufacturer's specification. Confirm runout with a dial indicator before beginning production cuts, as excessive runout will reduce tool life and surface finish quality.
