Accupro 12176890 Corner Radius End Mill 0.0469in 4 Flute

Product Description

The ACCUPRO 12176890 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 0.0469-inch mill diameter, a 0.01-inch corner radius, and four right-hand spiral flutes that deliver clean, consistent cuts. The cutting edges are coated with AlTiN (aluminum titanium nitride), which improves heat resistance and extends tool life during high-speed or dry machining. With a 9/64-inch length of cut and a 1/8-inch shank diameter, this end mill is sized for fine detail work. It is installed and used by machinists and CNC operators working with ferrous and non-ferrous materials.

This end mill is suited for slotting, profiling, and contouring in CNC machining centers and manual mills. The corner radius geometry reduces stress concentration at the cutting edge, making it a practical choice for finishing passes on hardened steels, stainless alloys, and similar materials. The single-end, centercutting design allows for plunge entry and versatile toolpath strategies. Its compact diameter makes it appropriate for fine-feature work in die and mold, aerospace component, and precision parts manufacturing environments.

Key Features

• AlTiN coating improves thermal resistance and extends tool life in high-speed dry cutting
• 0.01-inch corner radius reduces edge chipping and stress concentration during finishing passes
• Solid micrograin carbide construction provides rigidity and dimensional stability
• Four right-hand spiral flutes for efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• 1/8-inch shank diameter fits standard collets for compact CNC and manual mill setups

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC machining centers and manual mills accepting a 1/8-inch collet or tool holder.

Installation Notes

This end mill is installed and changed by machinists or CNC setup technicians. Always power down and lock out the spindle before changing tooling. Verify collet size and runout with a dial indicator before operation. Do not exceed the tool manufacturer recommended depth-of-cut or feed rates for the workpiece material and coating type.
