Accupro 95168308 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The ACCUPRO 95168308 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 1/2-inch diameter with a 0.0600-inch corner radius, a 4-flute spiral configuration, and a stub-length 5/8-inch length of cut. The micrograin solid carbide substrate delivers hardness and wear resistance across a wide range of workpiece materials. An AlTiN (aluminum titanium nitride) coating adds thermal protection and surface hardness, extending tool life in dry and high-speed cutting conditions. This end mill is centercutting, allowing plunge entry, and runs in a right-hand cutting direction with a right-hand flute spiral.

This tool is suited for professional machinists and tool-and-die shops running CNC vertical machining centers, knee mills, or similar equipment. It is used for profile milling, slotting, and contour work where a radiused corner is required to reduce stress concentrations or meet part geometry specifications. The stub length and variable helix geometry make it well-suited for applications requiring rigidity in tighter setups. A single-end configuration maximizes cutting performance per tool.

Key Features

• 0.0600-inch corner radius reduces stress concentrations and prevents sharp corner chipping
• AlTiN coating provides high thermal resistance for extended tool life in ferrous and hardened materials
• Variable helix flute geometry reduces harmonic vibration and chatter during cut
• Centercutting design allows direct plunge entry without pre-drilling
• Micrograin solid carbide construction maintains edge sharpness and dimensional accuracy
• Stub-length body increases rigidity for tighter tolerance work

Compatibility

Designed as an OEM-style replacement or standard tooling selection for 1/2-inch straight-shank ER or end mill holders on CNC machining centers and manual mills requiring a corner radius end mill configuration.

Installation Notes

Installation is performed by qualified machinists using an appropriate collet chuck or end mill holder matched to the 1/2-inch shank diameter. Ensure the holder and spindle are clean and free of debris before seating the tool. Confirm runout within machine tolerances before engaging the cut. Follow shop safety procedures and machine manufacturer guidelines for spindle speed and feed rate selection.
