Accupro 12182525 Square End Mill 23/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182525 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 23/64-inch (0.3594 inch) cutting diameter, a 7/8-inch length of cut, and a 3/8-inch shank diameter, with an overall length of 2.5 inches. The AlTiN coating provides heat and wear resistance for extended tool life in high-temperature cutting environments. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. This end mill is installed and used by machinists and tool-and-die professionals in CNC and manual milling applications.

This end mill suits general-purpose and finishing milling operations in shop and production environments. Its centercutting design allows for plunge entry as well as peripheral and slot milling. The regular length geometry makes it appropriate for standard reach applications where rigidity is prioritized. Right-hand cut and right-hand flute configuration follow conventional milling machine spindle direction for most vertical and horizontal mills.

Key Features

• 23/64-inch (0.3594 inch) cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inches
• AlTiN finish for elevated heat resistance and extended tool life in demanding cuts
• 40-degree helix angle with spiral flute geometry for improved chip flow
• Centercutting design allows plunge milling entry without pre-drilled holes
• Micrograin solid carbide construction for hardness and edge retention
• Right-hand cut and right-hand flute - standard configuration for conventional spindle rotation

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 3/8-inch straight shank. Suitable for milling ferrous metals, non-ferrous alloys, and similar materials where carbide tooling with AlTiN coating is specified.

Installation Notes

Installation is performed by machinists using an appropriate collet or end mill holder sized for a 3/8-inch shank. Ensure the machine spindle is fully stopped and locked before changing tooling. Verify runout with a dial indicator after seating to confirm proper tool engagement. Follow the machine manufacturer and tooling manufacturer feeds-and-speeds guidelines for the specific workpiece material.
