Accupro 12179732 Square End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12179732 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 3/8 inch cutting diameter with a 1-1/2 inch length of cut, a matching 3/8 inch shank diameter, and a 3-1/2 inch overall length. The three-flute, spiral geometry runs at a 40-degree helix angle with a zirconium nitride (ZrN) finish. Micrograin carbide construction delivers hardness and edge retention well suited to demanding cut cycles. This is a right-hand cut, right-hand flute, centercutting tool, meaning it can plunge directly into the workpiece as well as execute side and slot cuts.

This end mill fits long-series milling operations where extended reach or deeper pockets require additional length of cut beyond standard tooling. It is suited for ferrous and non-ferrous materials in CNC machining centers, manual knee mills, and high-speed spindle applications. The ZrN coating reduces friction and built-up edge, making it a practical choice for aluminum, brass, and similar materials. Machinists, tool and die makers, and CNC operators in job shops and production environments are the primary users.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• ZrN finish reduces friction and resists built-up edge
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute for standard spindle operation
• Long-series length of cut range of 1.5 to 2.0 inches supports deeper pocket milling

Compatibility

Designed as an OEM-style solid carbide square end mill compatible with standard 3/8 inch ER collets, milling chucks, and shrink-fit holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in a locked-out state. Seat the shank fully into the tool holder to the recommended gauge length before tightening to the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut cycle. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
