Accupro 95168831 Corner Radius End Mill 5/8 in 5 Flute

Product Description

The ACCUPRO 95168831 is a solid carbide corner radius end mill designed for high-performance milling in ferrous and hard materials. It features a 5/8-inch cutting diameter, a 0.030-inch corner radius, and five flutes with a variable helix geometry that reduces chatter and improves chip evacuation during aggressive cuts. The AlTiN coating provides thermal resistance and extended tool life in dry or high-speed machining conditions. This is a single-end, centercutting tool, meaning it can plunge directly into the workpiece. It is installed and operated by machinists and CNC programmers in job shop, production, and tool-and-die environments.

This end mill is suited for side milling, profiling, and slotting operations where a controlled corner radius is required to reduce stress concentrations at part corners. The 3/4-inch length of cut and 2-3/8-inch reach length make it appropriate for moderate-depth pockets and contoured surfaces. The extended reach design allows access to features that standard-length tools cannot reach. It performs best in CNC machining centers running right-hand spindle rotation, which matches the right-hand flute direction and cutting direction of this tool.

Key Features

• 0.030-inch corner radius reduces stress risers and improves surface finish at part corners
• Variable helix flute geometry minimizes vibration and chatter at higher feed rates
• AlTiN coating extends tool life in high-temperature, dry-cutting applications
• Centercutting design allows direct plunge entry into the workpiece
• Extended reach at 2-3/8 inches provides access to deep features and pockets
• Micrograin solid carbide substrate offers rigidity and edge retention in hard materials

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 5/8-inch collet or end mill holders on CNC machining centers and manual knee mills with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the 5/8-inch shank in a properly sized collet, hydraulic, or shrink-fit holder and verify runout before running at full feed and speed. Do not exceed the tool reach or depth-of-cut limits appropriate for the workpiece material and machine rigidity. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge integrity is compromised.
