Accupro 14797158 Square End Mill 1/32 in 3 Flute Carbide

Product Description

The ACCUPRO 14797158 is a solid carbide square end mill designed for precision milling in demanding machining applications. It features a 0.030-inch cutting diameter, a 0.045-inch length of cut, and a 1/8-inch shank diameter with an overall length of 2.5 inches. The three-flute geometry combined with a 30-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action. An AlTiN coating adds heat and wear resistance, making this tool well-suited for harder workpiece materials at elevated cutting speeds. The extended reach design and centercutting capability allow for slot milling, plunge entry, and work in confined or deep-pocket features. Machinists and toolroom technicians install and use this tool in CNC machining centers and manual mills.

This end mill is built for fine-detail and micro-milling work where a small-diameter, rigid cutting tool is required. The micrograin carbide substrate provides the toughness and edge retention needed when machining ferrous metals, hardened steels, stainless alloys, and similar materials at high RPM. The 0.250-inch reach length and compact cutting geometry make it appropriate for tight-tolerance slots, contours, and die-and-mold features where larger tools cannot reach. It is a single-end tool sold individually.

Key Features

• 0.030-inch cutting diameter with a tolerance of +0.0000 / -0.0010 inches for controlled dimensional output
• AlTiN coating improves heat resistance and tool life in ferrous and hardened material applications
• Centercutting design supports plunge milling and slot entry without a pre-drilled start hole
• 30-degree right-hand spiral flute promotes smooth chip flow and reduces cutting forces
• Micrograin solid carbide substrate delivers superior edge retention and rigidity in small-diameter tooling
• Extended reach of 0.250 inches allows access to deep or restricted features

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for CNC machining centers and manual milling machines accepting a 1/8-inch shank diameter collet or toolholder.

Installation Notes

A licensed machinist or toolroom technician should install and operate this end mill. Confirm the collet or toolholder bore matches the 1/8-inch shank before clamping, and verify shank runout with an indicator before cutting. Power down and de-energize the spindle completely before changing tooling. Follow the machine tool manufacturer guidelines and applicable shop safety protocols for RPM, feed rate, and depth of cut when using small-diameter carbide end mills, as they are susceptible to breakage under excessive load or misalignment.
