Accupro 95170993 Corner Radius End Mill 5/8 in 3 Flute Zrn

Product Description

The ACCUPRO 95170993 is a solid carbide, corner radius end mill designed for precision milling in ferrous and non-ferrous materials. It features a 0.6250 inch mill diameter with a 0.1200 inch corner radius, a 3-flute configuration, and a right-hand spiral flute with right-hand cutting direction. The 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. A ZrN (zirconium nitride) coating improves surface hardness and wear resistance, extending tool life in demanding operations. This single-end mill is centercutting, allowing direct plunge entry. It is specified for use by machinists and CNC operators in production and job shop environments.

This end mill suits extended-reach milling applications where standard-length tools cannot access deep pockets, cavities, or complex 3D contours. The 2.3750 inch reach length and reduced neck diameter of 0.5938 inches allow the tool to clear workpiece walls while maintaining rigidity. It is appropriate for finishing passes and semi-finishing in mold and die work, aerospace component machining, and precision part manufacturing. The 3/4 inch length of cut and 5 inch overall length support versatile setups on vertical machining centers and multi-axis CNC mills.

Key Features

• Solid carbide micrograin construction for rigidity and edge retention
• ZrN coating for increased wear resistance and reduced heat buildup
• 0.1200 inch corner radius reduces stress concentration and improves surface finish
• Extended reach design with 2.3750 inch reach length for deep-cavity access
• Centercutting geometry allows direct plunge milling
• 3-flute, right-hand spiral configuration balances chip clearance and cutting stability

Compatibility

Designed as an OEM-style replacement or direct substitution for solid carbide corner radius end mills with a 5/8 inch shank diameter and 5/8 inch mill diameter in standard ER or side-lock toolholders. No specific model compatibility was stated in the product data.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 5/8 inch shank fully in the toolholder to the recommended gauge line and torque the collet or set screw per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates edge wear on carbide tooling.
