Accupro 95170995 Corner Radius End Mill 5/8 in Carbide

Product Description

The ACCUPRO 95170995 is a solid carbide corner radius end mill designed for precision milling operations where edge integrity and surface finish are critical. It features a 5/8-inch diameter, a 3/4-inch length of cut, and a 0.120-inch corner radius that reduces stress concentrations at the cutting edge. The 37-degree variable-free helix promotes smooth chip evacuation and reduces chatter. A ZrN (zirconium nitride) coating adds hardness and heat resistance, extending tool life in demanding materials. The 3-flute, right-hand spiral geometry with centercutting capability allows for plunge entry. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill is suited for profiling, contouring, and slotting operations in ferrous and non-ferrous materials where a corner radius profile is required. The extended reach design, with a 1-5/8-inch reach length and a reduced neck diameter of 0.5938 inches, allows access to deeper pockets and stepped features without tool-holder interference. The 3-1/2-inch overall length provides additional clearance for workpiece fixtures. Micrograin carbide substrate supports tight tolerances and stable performance in high-speed or high-feed strategies.

Key Features

• 0.120-inch corner radius reduces edge chipping and improves corner strength
• ZrN coating increases surface hardness and thermal resistance
• Solid micrograin carbide substrate supports precision tolerances
• Extended reach with 1-5/8-inch reach length and reduced 0.5938-inch neck diameter
• Centercutting geometry enables direct plunge entry
• 3-flute right-hand spiral design for efficient chip evacuation

Compatibility

Designed as an OEM-style cutting tool for use in standard 5/8-inch collet chucks, end mill holders, or shrink-fit holders on CNC machining centers and manual knee mills accepting 5/8-inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or unloading the tool. Secure the shank to the published minimum insertion depth for the holder type in use. Verify runout with a dial indicator after tool loading, as excessive runout will accelerate wear and degrade corner radius accuracy.
