Accupro 95169659 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The ACCUPRO 95169659 is a solid carbide corner radius end mill designed for precision milling in demanding machining environments. It features a 5/8-inch (0.6250-inch) mill diameter, a 0.0300-inch corner radius, and four flutes with a right-hand spiral and right-hand cutting direction. The tool is coated with AlCrTiN via a PVD process, which improves heat resistance and tool life when cutting hard and abrasive materials. Variable index and variable helix geometry reduce chatter and vibration during cut. The Series VS designation indicates a short-length-of-cut configuration at 3/4 inch, suitable for rigid, high-feed operations. Machinists and CNC operators in production and job shop environments typically install and run this tool.

This end mill is used in milling applications that require a controlled corner radius to reduce stress concentrations in part features such as pocketing, slotting, and profiling. Its centercutting design allows plunge entry directly into the workpiece. The short 3/4-inch length of cut and straight-cylindrical 5/8-inch shank make it well suited for setups that prioritize rigidity and minimal deflection. It is appropriate for use on vertical and horizontal machining centers running ferrous and high-temperature alloy materials where AlCrTiN coatings perform best.

Key Features

• AlCrTiN PVD coating for high heat resistance and extended tool life in hard materials
• Variable helix and variable index flute geometry to suppress chatter and improve surface finish
• Centercutting design allows direct plunge milling without a pre-drilled entry hole
• Micrograin solid carbide substrate for hardness and wear resistance
• 0.0300-inch corner radius reduces edge chipping and stress concentrations on finished part features
• Short length-of-cut configuration maximizes rigidity in tight setups

Compatibility

Designed as an OEM-style replacement or direct-purchase option for 5/8-inch straight-cylindrical shank toolholders on CNC vertical and horizontal machining centers requiring a Series VS short corner radius end mill.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the toolholder bore and collet are clean and free of chips before seating the shank. Verify runout after installation using a dial indicator — the maximum TIR for this tool is 0.0048 inches. Follow the machine tool manufacturer and cutting tool manufacturer recommendations for speeds, feeds, and depth of cut before beginning any operation.
