Accupro 12179000 Square End Mill 3/16 Inch 4 Flute Carbide

Product Description

The ACCUPRO 12179000 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. Built to a stub length configuration with a 3/16 inch diameter and 3/8 inch length of cut, it delivers rigidity and resistance to deflection in tight-clearance machining setups. The nACRo physical vapor deposition coating improves wear resistance and reduces friction at elevated cutting temperatures. A 40-degree helix angle promotes efficient chip evacuation while maintaining smooth surface finishes. Four flutes provide increased material removal rates compared to two- or three-flute designs. This end mill is center-cutting, allowing direct plunge entry without a pre-drilled pilot hole.

This end mill is suited for CNC machining centers, vertical mills, and manual knee mills running ferrous steels, stainless alloys, and hardened materials where a tough, coated carbide tool is required. The stub length format makes it well suited for shallow-pocket milling, slotting, and profiling operations where tool overhang must be minimized to control vibration. Machinists and toolroom operators in job shops, production facilities, and maintenance departments commonly use this size for detail work on molds, fixtures, and close-tolerance components.

Key Features

• Solid carbide micrograin substrate for hardness and edge retention
• nACRo coating for extended tool life in abrasive and high-heat applications
• 40-degree spiral helix for efficient chip evacuation and reduced cutting forces
• Center-cutting geometry allows direct plunge milling without a pre-drilled hole
• Right-hand cut and right-hand flute configuration for standard spindle use
• Stub length design maximizes rigidity and minimizes deflection

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard 3/16 inch shank collets and tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank in a clean, properly sized collet or end mill holder, ensuring full engagement to the recommended grip depth. Power down and lock out the machine spindle before changing tooling. Verify runout with a dial indicator after installation to confirm concentricity before beginning a cut.
