Accupro 95172621 Corner Radius End Mill 5/8 in Solid Carbide

Product Description

The ACCUPRO 95172621 is a solid carbide corner radius end mill designed for precision milling in demanding machining environments. It features a 5/8 inch cutting diameter, a 0.0300 inch corner radius, and a 3-flute spiral geometry with right-hand cutting and flute direction. The ZrN (zirconium nitride) coating reduces friction and improves tool life in ferrous and non-ferrous applications. With a 37-degree helix angle and centercutting capability, this end mill handles plunge entry as well as peripheral and slot milling. The overall length is 3.5 inches, and the length of cut is 0.75 inches. It is manufactured from ultra fine micrograin solid carbide for consistent edge integrity and dimensional accuracy.

This end mill is suited for shops and machining professionals running CNC milling operations that require a tight corner radius and controlled surface finish. The Smart-Weldon shank type and 5/8 inch shank diameter make it compatible with standard toolholding systems. The stub-length, single-end configuration and extended reach design fit applications where a short flute length and rigidity are priorities. Typical uses include profiling, contouring, and pocket milling in tool steels, alloy steels, and similar materials where carbide grade and coating performance are critical.

Key Features

• 0.0300 inch corner radius with tolerance of +0.00000 to -0.00100 inches for consistent edge geometry
• ZrN coating for improved wear resistance and reduced heat buildup at the cutting edge
• Ultra fine micrograin solid carbide substrate for edge strength and dimensional stability
• Centercutting design allows plunge milling without a pre-drilled entry point
• 37-degree helix angle promotes efficient chip evacuation in deep pockets and slots
• Smart-Weldon shank type with h6 shank diameter tolerance for secure toolholder fitment
• Right-hand cut and right-hand flute direction; compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style replacement and standard-fit cutting tool for CNC machining centers and manual mills equipped with toolholders accepting a 5/8 inch Smart-Weldon or equivalent straight shank. Part of the ACCUPRO ST series.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout does not exceed the maximum TIR of 0.0004 inches before beginning the cut.
