Accupro 14797174 Square End Mill 1/32 in 3 Flute Carbide

Product Description

The ACCUPRO 14797174 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 1/32 inch (0.0312 inch) cutting diameter and a 0.155 inch length of cut, this tool is built for tight-tolerance work in confined areas and small-feature machining. The micrograin carbide construction provides hardness and edge retention well suited to high-speed CNC applications. Three flutes with a 30-degree right-hand helix balance chip evacuation and surface finish. The bright, uncoated finish makes it a general-purpose choice across a range of base materials. Machinists and toolroom operators typically specify this size for micro-slot milling, engraving profiles, and small-diameter pocket work.

This end mill fits applications requiring extended reach at small diameters. The 0.31 inch neck length and 2.5 inch overall length allow access into deeper cavities without tool holder interference. It is centercutting, allowing plunge entry. Typical install environments include CNC machining centers and manual mills running precision die, mold, and prototype work in production and job-shop settings. The 1/8 inch shank is compatible with standard collets and toolholders in that bore size.

Key Features

• Micrograin solid carbide construction for hardness and edge retention
• 3 flutes with 30-degree right-hand helix for balanced chip evacuation
• Centercutting geometry allows direct plunge entry
• Extended reach design with 0.31 inch neck length for deep-cavity access
• Bright uncoated finish suitable for general-purpose milling across multiple materials
• Mill diameter tolerance of +0.0000 / -0.0010 inch for consistent fit

Compatibility

Designed for use with standard 1/8 inch bore collets and toolholders on CNC machining centers and manual mills. Compatible with right-hand spindle rotation.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the spindle before inserting or removing the tool from the collet or toolholder. Ensure the shank is fully seated and the collet is torqued per the toolholder manufacturer specification. Verify runout with a dial indicator before initiating a cut, especially at this diameter, where even minor runout significantly affects tool life and feature accuracy.
