Accupro 12182115 Corner Radius End Mill 5/8 in 3 Flute Altin

Product Description

The ACCUPRO 12182115 is a solid carbide corner radius end mill designed for precision milling operations in demanding machining environments. It features a 5/8 inch diameter with a 0.045 inch corner radius, a 1-1/4 inch length of cut, and a 3-1/2 inch overall length. The three-flute, right-hand spiral geometry is paired with an AlTiN (aluminum titanium nitride) coating, which provides heat resistance and extended tool life in ferrous and hardened materials. Micrograin carbide construction adds edge retention and rigidity. This end mill is center-cutting and single-end, making it suitable for plunge entry and side milling in a single setup.

This end mill is used in CNC machining centers and manual mills for profiling, slotting, and contouring operations where a radiused corner is required to reduce stress concentrations or meet part drawing callouts. The AlTiN coating makes it well suited for dry or semi-dry cutting of alloy steels, stainless steels, cast iron, and hardened materials. It is installed by machinists and tool-and-die professionals in job shops, production facilities, and maintenance machining environments.

Key Features

• 5/8 inch mill diameter with 0.045 inch corner radius for reduced stress at part edges
• AlTiN coating for heat resistance and extended tool life in ferrous and hardened materials
• Three-flute, right-hand spiral design for efficient chip evacuation
• Center-cutting geometry allows plunge entry without a pre-drilled hole
• Micrograin solid carbide construction for rigidity and edge retention
• Single-end configuration with 5/8 inch shank diameter for standard ER and side-lock holders

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 5/8 inch shank end mill holder.

Installation Notes

Installation and tool changes must be performed with the machine in a full stop, lockout state. Secure the 5/8 inch shank in a properly sized collet or side-lock holder and torque the retention hardware to the holder manufacturer's specification. Inspect the tool shank and holder bore for chips or contamination before seating. Verify runout with a dial indicator before the first cut, as excessive runout will reduce tool life and surface finish quality.
