Accupro 95170983 Corner Radius End Mill 5/8 in Solid Carbide

Product Description

The ACCUPRO 95170983 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and extended reach capability. Manufactured from micrograin solid carbide and coated with ZrN (zirconium nitride), this tool delivers wear resistance and thermal stability in demanding cutting applications. It features a 5/8 inch mill diameter, a 3/4 inch length of cut, and a 3-1/2 inch overall length. The 0.030 inch corner radius reduces stress concentration at the cutting edge. With a 2-flute, right-hand spiral configuration and centercutting capability, it handles slotting, profiling, and plunge entry cuts. A licensed machinist or CNC programmer typically selects and installs this tool.

This end mill suits CNC machining centers and manual mills used in die and mold work, aerospace component machining, and general precision metalworking. The extended reach design, with a 1-5/8 inch reach length and a 0.5938 inch neck diameter, allows access to deeper pockets and stepped features without sacrificing rigidity. The 45-degree helix promotes smooth chip evacuation during medium to high-feed passes. The 5/8 inch shank diameter matches standard ER and side-lock collet systems common in production and job-shop environments.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• ZrN coating improves wear resistance and reduces built-up edge in ferrous and non-ferrous materials
• 0.030 inch corner radius reduces edge chipping and extends tool life in profiling operations
• Extended reach with 1-5/8 inch reach length and reduced neck diameter of 0.5938 inches for deep-pocket access
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute spiral with 45-degree helix for efficient chip flow

Compatibility

Designed as an OEM-style replacement or direct substitute for standard 5/8 inch shank corner radius end mills used in CNC machining centers and manual vertical mills with compatible collet or end mill holders.

Installation Notes

Installation is performed by a machinist or tooling technician. The machine spindle must be fully stopped and the tool holder secured before inserting or removing the end mill. Use a calibrated torque wrench on collet nuts per the tool holder manufacturer specification. Verify runout with a dial indicator after seating to ensure concentricity before cutting.
