Accupro 12179010 Square End Mill 11/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12179010 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide stock with a nACRo finish, this single-end tool delivers wear resistance and edge retention in demanding cutting conditions. The 4-flute spiral design with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.3437 inches in diameter with a 0.625-inch length of cut, it is sized for finishing passes and slot milling in tight geometries. Machinists and toolroom operators working in job shops and production environments install this tool in compatible CNC and manual milling machines.

This end mill is suited for milling steel, stainless steel, and other ferrous materials where a hard, wear-resistant coating is needed. The right-hand cut and right-hand flute configuration is the standard orientation for conventional and climb milling on vertical machining centers. Centercutting capability allows the tool to plunge directly into the workpiece without a pre-drilled pilot hole, expanding its utility for pocketing and profiling operations in both prototype and production environments.

Key Features

• Solid micrograin carbide construction for edge stability and extended tool life
• nACRo finish provides a wear-resistant coating suited to hard ferrous alloys
• 4-flute spiral design with 40-degree helix angle for balanced chip load and surface finish
• Centercutting geometry allows direct plunge entry without a pilot hole
• Right-hand cut, right-hand flute — standard orientation for most milling setups
• Single-end configuration; 0.375-inch shank fits standard ER and end mill holders

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC vertical machining centers and manual knee mills accepting a 3/8-inch shank end mill holder or collet chuck.

Installation Notes

Installation and tool changes must be performed with the machine spindle at a full stop and the machine in a locked or e-stop state. Seat the 0.375-inch shank fully into a matching collet or end mill holder and torque the retention nut to the holder manufacturer specification. Verify runout with a dial indicator before cutting; excessive runout accelerates edge wear and can cause premature tool failure. Follow applicable OSHA machine guarding requirements when operating milling equipment.
