Accupro 12183391 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 12183391 is a solid carbide square end mill designed for precision milling in a wide range of materials. Built from micrograin carbide and finished with a TiCN (Titanium Carbonitride) coating, this tool delivers hardness and wear resistance suited for ferrous and non-ferrous metals, alloys, and engineering plastics. It features a 0.125 inch mill diameter, a 0.75 inch length of cut, and a 2.25 inch overall length, placing it in the extra-long category for applications requiring extended reach. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Licensed machinists, tool-and-die makers, and CNC operators install and run this tool in production and job-shop environments.

This end mill is suited for slot milling, profiling, and plunge cutting operations on CNC machining centers and manual mills. The centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled pilot hole. The right-hand cut and right-hand spiral flute configuration is the standard for conventional CNC milling spindles. The extra-long overall length makes it appropriate for deep-cavity work, stepped features, and applications where standard-length tools cannot reach the full depth of cut.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating increases surface hardness and reduces friction at the cutting edge
• 40-degree helix angle for improved chip flow and reduced cutting forces
• Centercutting design enables direct plunge milling without a pilot hole
• 4 flutes provide a balance of chip clearance and surface finish quality
• Extra-long OAL of 2.25 inches supports deep-cavity and extended-reach applications

Compatibility

Designed as a standard 0.125 inch shank square end mill compatible with collet chucks, end mill holders, and shrink-fit toolholders accepting 0.125 inch shank diameters on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing the tool. Use a properly sized collet or toolholder to achieve full shank engagement and minimize runout. Follow the machine manufacturer and tooling manufacturer guidelines for speeds, feeds, and depth-of-cut parameters appropriate to the workpiece material.
