Accupro 12176887 Corner Radius End Mill 0.0469in 4 Flute

Product Description

The ACCUPRO 12176887 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. It measures 0.0469 inches in diameter with a 0.01 inch corner radius, making it well suited for fine detail work and corner blending in tight-tolerance applications. The tool features a TiCN (Titanium Carbonitride) coating that increases surface hardness and reduces friction during cutting. With 4 flutes and a right-hand spiral flute direction, it delivers efficient chip evacuation and a smooth finish. Machinists and tool-and-die professionals working with CNC machining centers will find this a reliable small-diameter option for finishing passes.

This end mill is used in precision machining environments including mold making, die work, and general CNC milling of hardened steels and alloy materials. The 9/64 inch (0.625 inches) length of cut, 1/8 inch shank diameter, and 1-1/2 inch overall length make it a compact, single-end tool for close-quarter work. The centercutting design allows for direct plunge entry. It is appropriate for both manual mills and CNC vertical machining centers where small-feature accuracy is required.

Key Features

• TiCN coating increases hardness and extends tool life in abrasive and hardened materials
• Micrograin solid carbide construction for rigidity and wear resistance in small-diameter applications
• 4-flute, right-hand spiral design promotes efficient chip removal and surface finish quality
• Centercutting geometry allows direct plunge cutting without pilot drilling
• 0.01 inch corner radius reduces stress concentrations at milled corners
• Single-end configuration with 1/8 inch shank for standard collet chuck compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard 1/8 inch collet toolholders used in CNC vertical machining centers and manual knee mills requiring small-diameter corner radius end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is secured in a clean, properly sized collet or end mill holder before tightening. Inspect the shank and collet bore for chips or damage prior to installation. Follow the machine tool manufacturer guidelines for runout tolerance and clamping torque appropriate to small-diameter carbide tooling.
