Accupro 95171398 Square End Mill 12mm 2 Flute Carbide Zrn

Product Description

The ACCUPRO 95171398 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 12 mm (0.4724 inch) cutting diameter and a 32 mm length of cut, this tool handles slotting, profiling, and peripheral milling in a single-end configuration. The 45-degree helix angle promotes efficient chip evacuation and reduced cutting forces. A zirconium nitride (ZrN) coating provides surface hardness and heat resistance, extending tool life in ferrous and non-ferrous applications. This end mill is installed and run by machinists and CNC operators in production and job-shop settings.

This end mill suits horizontal and vertical milling machines as well as CNC machining centers. The regular length configuration and 12 mm shank diameter make it compatible with standard ER collet chucks and end mill holders commonly found in production environments. With a micrograin carbide substrate and right-hand cutting and flute direction, it is appropriate for conventional and climb milling passes. The centercutting geometry allows for plunge entry when required by the operation.

Key Features

• 12 mm cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish
• ZrN (zirconium nitride) coating for improved wear resistance and thermal stability
• 45-degree helix angle for smooth chip flow and reduced cutting pressure
• Micrograin solid carbide substrate for rigidity and edge retention
• Centercutting design allows plunge milling capability
• Right-hand cut and right-hand flute spiral geometry for standard milling setups

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual milling machines accepting 12 mm straight shank end mills in ER collet or end mill holder tooling systems.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC operators familiar with end mill setup and speeds-and-feeds selection. Ensure the machine spindle and toolholder are fully de-energized and at rest before inserting or removing the end mill. Confirm shank diameter tolerance and holder bore compatibility before clamping. Do not exceed the manufacturer-rated depth of cut or feed rate for the workpiece material to avoid tool breakage.
