Accupro 12183174 Corner Radius End Mill 1in 4 Flute Ticn

Product Description

The ACCUPRO 12183174 is a solid carbide corner radius end mill designed for high-performance milling operations in metalworking and machining applications. It features a 1 inch cutting diameter, a 3 inch length of cut, and a 0.045 inch corner radius that reduces stress concentrations at the cutting edge. The 40-degree helix angle and TiCN coating improve chip evacuation and extend tool life in ferrous and non-ferrous materials. With 4 flutes and an extra-long 6 inch overall length, this tool is suited for deep-cavity and long-reach milling work. It is installed and operated by machinists and CNC tooling professionals.

This end mill is built for demanding cutting conditions where reach and edge integrity matter. The extra-long configuration makes it a practical choice for mold work, die machining, and deep-pocket profiling where standard-length tools cannot reach. The centercutting geometry allows plunge entry directly into the workpiece. Micrograin carbide construction supports tight tolerances and consistent performance across extended production runs in tool steels, stainless steels, aluminum, and similar materials.

Key Features

• 1 inch cutting diameter with a 0.045 inch corner radius for reduced edge chipping and improved surface finish
• 3 inch length of cut and 6 inch overall length for extra-long reach applications
• TiCN coating for enhanced wear resistance and heat resistance in ferrous materials
• 4-flute, right-hand spiral design with 40-degree helix angle for efficient chip evacuation
• Centercutting capable — supports direct plunge entry without pre-drilling
• Micrograin solid carbide construction for dimensional stability and extended tool life

Compatibility

Designed as an OEM-style replacement or direct tooling option for CNC machining centers and manual mills accepting a 1 inch straight shank end mill holder or collet.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Secure the shank firmly in a properly sized end mill holder or collet chuck, confirming runout is within acceptable limits before operation. Power down and lock out the spindle before changing or inspecting tooling. Follow the machine manufacturer guidelines for speeds and feeds appropriate to the workpiece material and tool diameter.
