Accupro 310162 Corner Radius End Mill 5/16 in 4-flute

Product Description

The ACCUPRO 310162 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 5/16-inch diameter, a 7/16-inch length of cut, and a 2-inch overall length. The 4-flute, right-hand spiral configuration with a 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlCrTiN coating provides thermal resistance and extended tool life in demanding cutting environments. The micrograin carbide substrate delivers edge integrity at high cutting speeds. Center cutting geometry allows plunge entry, making this tool suitable for slot milling, profiling, and ramping operations.

This end mill is used in CNC machining centers and manual mills for finishing and semi-finishing ferrous and hard alloy workpieces. The corner radius end type reduces stress concentration at the cutting edge and produces a controlled radius at the base of milled features. The straight-cylindrical shank seats securely in standard collet chucks and end mill holders. It is a single-end tool intended for production environments where consistent tolerances and repeatability are required. Machinists and CNC programmers working in job shops, tool rooms, and production machining facilities are the primary users.

Key Features

• AlCrTiN coating for high-temperature wear resistance in ferrous and hard-material cuts
• 4-flute, right-hand spiral design with 38-degree helix for efficient chip removal
• Center cutting capability allows direct plunge entry without pre-drilling
• Micrograin solid carbide substrate for edge stability and dimensional consistency
• Variable index flute spacing reduces harmonic vibration during cuts
• Corner radius geometry minimizes edge chipping and extends tool life at feature corners

Compatibility

Designed as an OEM-style replacement and standard production tool for use in standard 5/16-inch collet chucks, shrink-fit holders, and end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and the control in an e-stop or lockout state. Seat the straight-cylindrical shank fully into the holder and tighten to the holder manufacturer's specified clamping procedure. Inspect the corner radius and cutting edges under magnification before use to confirm the tool arrived undamaged. Follow your facility's speeds-and-feeds library for solid carbide end mills with AlCrTiN coating when establishing initial cutting parameters.
