Accupro 315363 Corner Radius End Mill 1/8 in Solid Carbide

Product Description

The ACCUPRO 315363 is a solid carbide corner radius end mill designed for precision milling applications requiring extended reach and a fine corner profile. Built from micrograin solid carbide and coated with ZrN (zirconium nitride), this tool delivers hardness and heat resistance in demanding cutting environments. The 1/8 inch diameter cutter features a 0.0200 inch corner radius, a 1/4 inch length of cut, and a 3-inch overall length with a 1-3/8 inch reach length. The three-flute, right-hand spiral configuration with a 37-degree helix supports efficient chip evacuation and smooth surface finishes. Centercutting capability allows plunge entry. Installed by machinists and CNC operators in production and job shop environments.

This end mill is suited for finishing and semi-finishing operations in molds, dies, and precision components where a radiused corner is required. The extended reach geometry allows access to deep pockets and stepped features without tool holder interference. The ZrN coating improves wear resistance and reduces friction, making it effective in ferrous and non-ferrous materials. The 1/8 inch shank matches the cutter diameter, and the reduced neck diameter of 0.1188 inches allows clearance in narrow profiles. Typical applications include aerospace, medical, and mold-making operations where tight tolerances and surface finish consistency are critical.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• ZrN coating reduces friction and extends tool life in demanding cuts
• 0.0200 inch corner radius protects edges and produces radiused floors
• Extended reach with 1-3/8 inch reach length for deep pocket access
• Centercutting design allows direct plunge entry
• Three-flute right-hand spiral geometry promotes chip evacuation

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 1/8 inch straight shank tool holder or collet.

Installation Notes

Installation is performed by machinists using a compatible collet or end mill holder rated for 1/8 inch straight shanks. Ensure the spindle and tool holder are clean and free of chips before seating the tool. Verify runout with a dial indicator before cutting to protect the reduced neck geometry. Follow machine manufacturer guidelines and applicable shop safety procedures when setting tool offsets and feed rates.
